It&apos;s not always clear how much this is a real problem for artificial intelligence. When we ask humans to explain their reasoning, they routinely rationalize, typically completely unaware that they&apos;re even doing so, giving most plausible explanations for themselves without any indication of what&apos;s really going on in their heads. </p><p>We already know how to get AI models to make up plausible answers. Maybe artificial intelligence is more like humans in that way than we&#x2019;d like to admit.</p><p>Fifty years ago, the American philosopher Thomas Nagel wrote an influential essay called <em>What Is It Like To Be A Bat?</em> He contended that there must be something that it&#x2019;s like to be a bat: To see the world as a bat sees it, and to perceive existence in the way a bat does. However, according to Nagel, even if we knew every knowable fact about how bat brains, bat senses, and bat bodies work, we still wouldn&#x2019;t know what it&#x2019;s like to be a bat.</p><p>AI explainability is the same kind of problem. We know every fact there is to know about a given AI model. It&#x2019;s just a lot of finite-precision numbers arranged in a sequence of matrices. We can trivially verify that every model output is the result of correct arithmetic, but that information is useless as an explanation.</p><p>There is no more a general solution to this problem for AI than there is for humans. However, the ColBERT architecture, and particularly how it uses &#x201C;late interaction&#x201D; when used as a reranker, enables you to get meaningful insights from your models about why it gives specific results in particular cases.</p><p>This article shows you how late interaction enables explainability, using the Jina-ColBERT model <a href="https://huggingface.co/jinaai/jina-colbert-v1-en?ref=jina-ai-gmbh.ghost.io"><code>jina-colbert-v1-en</code></a> and the <a href="https://matplotlib.org/?ref=jina-ai-gmbh.ghost.io">Matplotlib Python library</a>.</p><h2 id="a-brief-overview-of-colbert">A Brief Overview of ColBERT</h2><p>ColBERT was introduced in <a href="https://doi.org/10.1145/3397271.3401075?ref=jina-ai-gmbh.ghost.io">Khattab &amp; Zaharia (2020)</a> as an extension to the <a href="https://doi.org/10.18653/v1/N19-1423?ref=jina-ai-gmbh.ghost.io">BERT model first introduced in 2018</a> by Google. <a href="https://jina.ai/news/what-is-colbert-and-late-interaction-and-why-they-matter-in-search/?ref=jina-ai-gmbh.ghost.io">Jina AI&#x2019;s Jina-ColBERT</a> models draw on this work and the later ColBERT v2 architecture proposed in <a href="https://arxiv.org/abs/2112.01488?ref=jina-ai-gmbh.ghost.io">Santhanam, et al. (2021)</a>. ColBERT-style models can be used to create embeddings, but they have some additional features when used as a reranking model. The main benefit is <em>late interaction</em>, which is a way of structuring the problem of semantic text similarity differently from standard embedding models.</p><h3 id="embedding-models">Embedding Models</h3><p>In a traditional embedding model, we compare two texts by generating representative vectors for them called <em>embeddings</em>, and then we compare those embeddings via distance metrics like cosine or Hamming distance. Quantifying the semantic similarity of two texts generally follows a common procedure.</p><p>First, we create embeddings for the two texts separately. For any one text:</p><ol><li>A tokenizer breaks the text up into roughly word-sized chunks.</li><li>Each token is mapped to a vector.</li><li>The token vectors interact via the attention system and convolution layers, adding context information to the representation of each token.</li><li>A pooling layer transforms these modified token vectors into a single embedding vector.</li></ol><figure class="kg-card kg-image-card kg-card-hascaption"><img src="https://jina-ai-gmbh.ghost.io/content/images/2024/06/Embeddings_pooling_dark_small-1.png" class="kg-image" alt="AI Explainability Made Easy: How Late Interaction Makes Jina-ColBERT Transparent" loading="lazy" width="550" height="900"><figcaption><span style="white-space: pre-wrap;">A schematized embedding model that creates a single embedding for a text.</span></figcaption></figure><p>Then, when there is an embedding for each text, we compare them to each other, typically using the cosine metric or Hamming distance.</p><figure class="kg-card kg-image-card kg-card-hascaption"><img src="https://jina-ai-gmbh.ghost.io/content/images/2024/06/Embeddings2_simpler_dark_small.png" class="kg-image" alt="AI Explainability Made Easy: How Late Interaction Makes Jina-ColBERT Transparent" loading="lazy" width="775" height="825" srcset="https://jina-ai-gmbh.ghost.io/content/images/size/w600/2024/06/Embeddings2_simpler_dark_small.png 600w, https://jina-ai-gmbh.ghost.io/content/images/2024/06/Embeddings2_simpler_dark_small.png 775w" sizes="(min-width: 720px) 720px"><figcaption><span style="white-space: pre-wrap;">In a conventional embedding model, documents are compared by directly comparing their embeddings.</span></figcaption></figure><p>Scoring happens by comparing the two whole embeddings to each other, without any specific information about the tokens. All the interaction between tokens is &#x201C;early&#x201D; since it occurs before the two texts are compared to each other.</p><h3 id="reranking-models">Reranking Models</h3><p>Reranking models work differently.</p><p>First, instead of creating an embedding for any text, it takes one text, called a <em>query</em>, and a collection of other texts that we&apos;ll all <em>target documents</em> and then scores each target document with respect to the query text. These numbers are not normalized and are not like comparing embeddings, but they are sortable. The target documents that score the highest with respect to the query are the texts that are most semantically related to the query according to the model.</p><p>Let&#x2019;s look at how this works concretely with the <code>jina-colbert-v1-en</code> reranker model, using the Jina Reranker API and Python.</p><p>The code below is also in a notebook which you can <a href="https://raw.githubusercontent.com/jina-ai/workshops/main/notebooks/heatmaps/colbert_heatmaps.ipynb?ref=jina-ai-gmbh.ghost.io" rel="noreferrer">download</a> or <a href="https://colab.research.google.com/github/jina-ai/workshops/blob/main/notebooks/heatmaps/colbert_heatmaps.ipynb?ref=jina-ai-gmbh.ghost.io" rel="noreferrer">run in Google Colab</a>.</p><p>You should install the most recent version of the <code>requests</code> library into your Python environment first.

Each square shows the interaction between two tokens, one from each text. The extra tokens <code>[CLS]</code> and <code>[SEP]</code> indicate the beginning and the end of the text respectively, and <code>q</code> and <code>d</code> are inserted right after the <code>[CLS]</code> token in queries and target documents respectively. This allows the model to take into account interactions between tokens and the beginning and ends of texts but also allows token representations to be sensitive to whether they are in queries or targets.</p><p>The brighter the square, the more interaction there is between the two tokens, which is indicative of being semantically related. Each token pair&#x2019;s interaction score is in the range -1.0 to 1.0. The squares highlighted by a red frame are the ones that count towards the final score: For each token in the query, it&#x2019;s highest interaction level with any document token is the value that counts.</p><p>The best matches &#x2014; the brightest spots &#x2014; and the red-framed maximum values are almost all exactly on the diagonal, and they have very strong interaction. The only exceptions are the &#x201C;technical&#x201D; tokens <code>[CLS]</code>, <code>q</code>, and <code>d</code>, as well as the word &#x201C;of&#x201D; which is a high-frequency &#x201C;stop word&#x201D; in English that carries very little independent information.</p><p>Let&#x2019;s take a structurally similar sentence &#x2014; &#x201C;Cats eat 50 g of food per day.&#x201D; &#x2014; and see how the tokens in it interact:</p><pre><code class="language-Python">create_heatmap(&quot;Elephants eat 150 kg of food per day.&quot;, &quot;Cats eat 50 g of food per day.&quot;)</code></pre><figure class="kg-card kg-image-card"><img src="https://jina-ai-gmbh.ghost.io/content/images/2024/06/download.png" class="kg-image" alt="AI Explainability Made Easy: How Late Interaction Makes Jina-ColBERT Transparent" loading="lazy" width="640" height="480" srcset="https://jina-ai-gmbh.ghost.io/content/images/size/w600/2024/06/download.png 600w, https://jina-ai-gmbh.ghost.io/content/images/2024/06/download.png 640w"></figure><p>Once again, the best matches are primarily on the diagonal because the words are frequently the same and the sentence structure is nearly identical.

<h3 id="long-texts">Long Texts</h3><p>These are toy examples to demonstrate the workings of ColBERT-style reranker models.

Almost everything we do is based on the idea that complex, learnable relationships in input data can be expressed in the geometry of high-dimensional spaces. However, it&#x2019;s very difficult for mere humans to make sense of spatial relationships in thousands to millions of dimensions.</p><p>ColBERT is a step back from that level of abstraction. It&#x2019;s not a complete answer to the problem of explaining what an AI model does, but it points us directly at which parts of our data are responsible for our results.</p><p>Sometimes, AI has to be a black box. The giant matrices that do all the heavy lifting are too big for any human to keep in their heads. But the ColBERT architecture shines a little bit of light into the box and demonstrates that more is possible.</p><p>The Jina-ColBERT model is currently available only for English (<code>jina-colbert-v1-en</code>) but more languages and usage contexts are on their way.

CLIP has a straightforward yet ingenious architecture: it combines two embedding models, one for texts and one for images, into a single model with a single output embedding space. Its text and image embeddings are directly comparable to each other, making the distance between a text embedding and an image embedding proportionate to how well that text describes the image, and vice versa.</p><p>This has proven to be very useful in multimodal information retrieval and zero-shot image classification. Without further special training, CLIP performed well at placing images into categories with natural language labels.</p><figure class="kg-card kg-image-card"><img src="https://jina-ai-gmbh.ghost.io/content/images/2024/06/180-1.jpg" class="kg-image" alt="Jina CLIP v1: A Truly Multimodal Embeddings Model for Text and Image" loading="lazy" width="1600" height="900" srcset="https://jina-ai-gmbh.ghost.io/content/images/size/w600/2024/06/180-1.jpg 600w, https://jina-ai-gmbh.ghost.io/content/images/size/w1000/2024/06/180-1.jpg 1000w, https://jina-ai-gmbh.ghost.io/content/images/2024/06/180-1.jpg 1600w" sizes="(min-width: 720px) 720px"></figure><p>The text embedding model in the original CLIP was a custom neural network with only 63 million parameters. On the image side, OpenAI released CLIP with a selection of <a href="https://huggingface.co/docs/transformers/model_doc/resnet?ref=jina-ai-gmbh.ghost.io" rel="noopener noreferrer">ResNet</a> and <a href="https://huggingface.co/docs/transformers/en/model_doc/vit?ref=jina-ai-gmbh.ghost.io" rel="noopener noreferrer">ViT models</a>. Each model was pre-trained for its individual modality and then trained with captioned images to produce similar embeddings for prepared image-text pairs.</p><figure class="kg-card kg-image-card"><img src="https://jina-ai-gmbh.ghost.io/content/images/2024/06/Blog-images--1-.png" class="kg-image" alt="Jina CLIP v1: A Truly Multimodal Embeddings Model for Text and Image" loading="lazy" width="1600" height="900" srcset="https://jina-ai-gmbh.ghost.io/content/images/size/w600/2024/06/Blog-images--1-.png 600w, https://jina-ai-gmbh.ghost.io/content/images/size/w1000/2024/06/Blog-images--1-.png 1000w, https://jina-ai-gmbh.ghost.io/content/images/2024/06/Blog-images--1-.png 1600w" sizes="(min-width: 720px) 720px"></figure><p>This approach yielded impressive results. Particularly notable is its zero-shot classification performance. For example, even though the training data did not include labeled images of <a href="https://docs.vultr.com/zero-shot-image-classification-using-openai-clip?ref=jina-ai-gmbh.ghost.io">astronauts</a>, CLIP could correctly identify pictures of astronauts based on its understanding of related concepts in texts and images.</p><p>However, OpenAI&#x2019;s CLIP has two important drawbacks:</p><ul><li>First is its very limited text input capacity. It can take a maximum 77 tokens of input, but <a href="https://arxiv.org/abs/2403.15378?ref=jina-ai-gmbh.ghost.io">empirical analysis shows</a> that in practice it doesn&#x2019;t use more than 20 tokens to produce its embeddings. This is because CLIP was trained from images with captions, and captions tend to be very short. This is in contrast to current text embedding models which support several thousand tokens.</li><li>Second, the performance of its text embeddings in text-only retrieval scenarios is very poor. Image captions are a very limited kind of text, and do not reflect the broad array of use cases a text embedding model would be expected to support.</li></ul><p>In most real use cases, text-only and image-text retrieval are combined or at least both are available for tasks. Maintaining a second embeddings model for text-only tasks effectively doubles the size and complexity of your AI framework.</p><p>Jina AI&#x2019;s new model addresses these issues directly, and <code>jina-clip-v1</code> takes advantage of the progress made in the last several years to bring state-of-the-art performance to tasks involving all combinations of text and image modalities.</p><h2 id="introducing-jina-clip-v1">Introducing Jina CLIP v1</h2><p>Jina CLIP v1 retains the OpenAI&#x2019;s original CLIP schema: two models co-trained to produce output in the same embedding space.</p><p>For text encoding, we adapted the <a href="https://jina.ai/news/jina-embeddings-2-the-best-solution-for-embedding-long-documents/?ref=jina-ai-gmbh.ghost.io">Jina BERT v2</a> architecture used in the <a href="https://jina.ai/embeddings/?ref=jina-ai-gmbh.ghost.io">Jina Embeddings v2 models</a>. This architecture supports a state-of-the-art 8k token input window and outputs 768-dimensional vectors, producing more accurate embeddings from longer texts. This is more than 100 times the 77 token input supported in the original CLIP model.</p><p>For image embeddings, we are using the latest model from the Beijing Academy for Artificial Intelligence: the <a href="https://github.com/baaivision/EVA/tree/master/EVA-02?ref=jina-ai-gmbh.ghost.io"><code>EVA-02</code> model</a>. We have empirically compared a number of image AI models, testing them in cross-modal contexts with similar pre-training, and <code>EVA-02</code>clearly outperformed the others. It&#x2019;s also comparable to the Jina BERT architecture in model size, so that compute loads for image and text processing tasks are roughly identical.</p><p>These choices produce important benefits for users:</p><ul><li>Better performance on all benchmarks and all modal combinations, and especially large improvements in text-only embedding performance.</li><li><code>EVA-02</code>&apos;s empirically superior performance both in image-text and image-only tasks, with the added benefit of Jina AI&#x2019;s additional training, improving image-only performance.</li><li>Support for much longer text inputs. <a href="https://jina.ai/news/jina-ai-launches-worlds-first-open-source-8k-text-embedding-rivaling-openai/?ref=jina-ai-gmbh.ghost.io">Jina Embeddings&#x2019; 8k token</a> input support makes it possible to process detailed textual information and correlate it with images.</li><li>A large net savings in space, compute, code maintenance, and complexity because this multimodal model is highly performant even in non-multimodal scenarios.</li></ul><h3 id="training">Training</h3><p>Part of our recipe for high-performance multimodal AI is our training data and procedure. We notice that the very short length of texts used in image captions is the major cause of poor text-only performance in CLIP-style models, and our training is explicitly designed to remedy this.</p><figure class="kg-card kg-image-card"><img src="https://jina-ai-gmbh.ghost.io/content/images/2024/06/dark-1.png" class="kg-image" alt="Jina CLIP v1: A Truly Multimodal Embeddings Model for Text and Image" loading="lazy" width="1600" height="900" srcset="https://jina-ai-gmbh.ghost.io/content/images/size/w600/2024/06/dark-1.png 600w, https://jina-ai-gmbh.ghost.io/content/images/size/w1000/2024/06/dark-1.png 1000w, https://jina-ai-gmbh.ghost.io/content/images/2024/06/dark-1.png 1600w" sizes="(min-width: 720px) 720px"></figure><p>Training takes place in three steps:</p><ol><li>Use captioned image data to learn to align image and text embeddings, interleaved with text pairs with similar meanings. This co-training jointly optimizes for the two kinds of tasks. The text-only performance of the model declines during this phase, but not as much as if we had trained with only image-text pairs.</li><li>Train using synthetic data which aligns images with larger texts, generated by an AI model, that describes the image. Continue training with text-only pairs at the same time. During this phase, the model learns to attend to larger texts in conjunction with images.</li><li>Use text triplets with <a href="https://finetuner.jina.ai/advanced-topics/negative-mining/?ref=jina-ai-gmbh.ghost.io" rel="noreferrer">hard negatives</a> to further improve text-only performance by learning to make finer semantic distinctions.

<script async src="https://platform.twitter.com/widgets.js" charset="utf-8"></script></figure><h2 id="two-problems-of-rag">Two problems of RAG</h2><p>I see two problems with the RAG frameworks and solutions we have today. </p><h2 id="feed-forward-only">Feed-forward only</h2><p>First, nearly all RAG frameworks <strong>implement only a &quot;feed-forward&quot; path and lack a &quot;back-propagation&quot; path</strong>. It is an <em>incomplete</em> system. I remember <a href="https://x.com/swyx?ref=jina-ai-gmbh.ghost.io">@swyx</a>, in one of the episodes of <a href="https://x.com/latentspacepod?ref=jina-ai-gmbh.ghost.io">@latentspacepod</a>, arguing that RAG will <em>not</em> be killed by the long context window of LLMs since:</p><ol><li>long context is expensive for devs and</li><li>long context is hard to debug and lacks decomposability. </li></ol><p>But if all RAG frameworks focus only on the forwarding path, how is it easier to debug than an LLM? It is also interesting how many people get overexcited by the auto-magical results of RAG from some random POCs and completely forget that adding more forward layers without backward tuning is a terrible idea. We all know that adding one more layer to your neural networks expands its parametric space and hence representation ability, enabling it to do more potential things, <strong>but without training, this is nothing. </strong>There are quite some startups in the Bay Area working on evaluation&#x2014;essentially trying to evaluate the loss of a feed-forward system. Is it useful? Yes. But does it help close the loop of RAG? No.<br><br>So who is working on the back-propagation of RAG? Afaik not many. I am mostly familiar with DSPy, a library from <a href="https://x.com/stanfordnlp?ref=jina-ai-gmbh.ghost.io">@stanfordnlp</a> <a href="https://x.com/lateinteraction?ref=jina-ai-gmbh.ghost.io">@lateinteraction</a> that sets its mission on that. </p><figure class="kg-card kg-bookmark-card"><a class="kg-bookmark-container" href="https://github.com/stanfordnlp/dspy?ref=jina-ai-gmbh.ghost.io"><div class="kg-bookmark-content"><div class="kg-bookmark-title">GitHub - stanfordnlp/dspy: DSPy: The framework for programming&#x2014;not prompting&#x2014;foundation models</div><div class="kg-bookmark-description">DSPy: The framework for programming&#x2014;not prompting&#x2014;foundation models - stanfordnlp/dspy</div><div class="kg-bookmark-metadata"><img class="kg-bookmark-icon" src="https://github.githubassets.com/assets/pinned-octocat-093da3e6fa40.svg" alt="RAG is Dead, Again?"><span class="kg-bookmark-author">GitHub</span><span class="kg-bookmark-publisher">stanfordnlp</span></div></div><div class="kg-bookmark-thumbnail"><img src="https://opengraph.githubassets.com/0d188663ed7e46ec4bb66d2eb8c5a9417e63343bc566e659a691978ae3df0b3e/stanfordnlp/dspy" alt="RAG is Dead, Again?"></div></a></figure><p>But even for DSPy, the main focus is on optimizing few-shot demonstrations, not the full system (or at least from community usage). But why is this problem difficult? Because the signal is very sparse, and optimizing a non-differentiable pipeline system is essentially a combinatorial problem&#x2014;in other words, <strong>extremely hard</strong>. I learned some submodular optimization during my PhD, and I have a feeling that this technique will be put to good use in RAG optimization.</p><h2 id="grounding-in-the-wild-is-hard">Grounding in the wild is hard</h2><p>I do agree that RAG is for grounding, despite the funny search results from Google. There are two types of grounding: <strong>search grounding</strong>, which uses search engines to extend the world knowledge of LLMs, and <strong>check grounding</strong>, which uses private knowledge (e.g. proprietary data) to do fact-checking. </p><p>In both cases, it cites external knowledge to improve the factuality of the result, provided that these external resources are trustworthy. In Google&apos;s funny search result, one can easily see that not everything on the web is trustworthy (yeah, big surprise, who would thought!), which makes search grounding look bad. But I do believe you can only laugh at it for now. There are some <strong>implicit feedback mechanisms</strong> behind the Google Search UI that collect users&apos; reactions to those results and weight the credibility of the website for better grounding. In general, it should be pretty temporary, as this RAG just needs to get past<strong> the cold start</strong>, and results will improve over time.</p><figure class="kg-card kg-image-card kg-card-hascaption"><img src="https://jina-ai-gmbh.ghost.io/content/images/2024/05/Heading--32-.png" class="kg-image" alt="RAG is Dead, Again?" loading="lazy" width="1500" height="787" srcset="https://jina-ai-gmbh.ghost.io/content/images/size/w600/2024/05/Heading--32-.png 600w, https://jina-ai-gmbh.ghost.io/content/images/size/w1000/2024/05/Heading--32-.png 1000w, https://jina-ai-gmbh.ghost.io/content/images/2024/05/Heading--32-.png 1500w" sizes="(min-width: 720px) 720px"><figcaption><span style="white-space: pre-wrap;">Two types of grounding that inspire </span><a href="https://jina.ai/reader/?ref=jina-ai-gmbh.ghost.io"><span style="white-space: pre-wrap;">Jina Reader</span></a></figcaption></figure><figure class="kg-card kg-gallery-card kg-width-wide kg-card-hascaption"><div class="kg-gallery-container"><div class="kg-gallery-row"><div class="kg-gallery-image"><img src="https://jina-ai-gmbh.ghost.io/content/images/2024/05/GOVSJD9XEAAf2kK.jpeg" width="2000" height="955" loading="lazy" alt="RAG is Dead, Again?" srcset="https://jina-ai-gmbh.ghost.io/content/images/size/w600/2024/05/GOVSJD9XEAAf2kK.jpeg 600w, https://jina-ai-gmbh.ghost.io/content/images/size/w1000/2024/05/GOVSJD9XEAAf2kK.jpeg 1000w, https://jina-ai-gmbh.ghost.io/content/images/size/w1600/2024/05/GOVSJD9XEAAf2kK.jpeg 1600w, https://jina-ai-gmbh.ghost.io/content/images/size/w2400/2024/05/GOVSJD9XEAAf2kK.jpeg 2400w" sizes="(min-width: 720px) 720px"></div><div class="kg-gallery-image"><img src="https://jina-ai-gmbh.ghost.io/content/images/2024/05/Untitled.jpg" width="2000" height="975" loading="lazy" alt="RAG is Dead, Again?" srcset="https://jina-ai-gmbh.ghost.io/content/images/size/w600/2024/05/Untitled.jpg 600w, https://jina-ai-gmbh.ghost.io/content/images/size/w1000/2024/05/Untitled.jpg 1000w, https://jina-ai-gmbh.ghost.io/content/images/size/w1600/2024/05/Untitled.jpg 1600w, https://jina-ai-gmbh.ghost.io/content/images/size/w2400/2024/05/Untitled.jpg 2400w" sizes="(min-width: 720px) 720px"></div></div></div><figcaption><p><span style="white-space: pre-wrap;">RAG was presented as a grounding solution in the Google Next conference.</span></p></figcaption></figure><h2 id="my-take">My Take</h2><p>RAG is neither dead nor alive; so stop arguing about it.

While each of these <em>can</em> achieve good results, they have different strengths and weaknesses.</p><p>Looking at DALL-E 3, out of the box it&#x2019;s good at understanding long sentences and object relationships, and it draws more realistic anatomy than Stable Diffusion XL (no Lovecraftian horror hands here). However, it often point-blank refuses to generate images of notable figures (like Taylor Swift) or well-known characters (like Mickey Mouse, even if we ask for the out-of-copyright Steamboat Willie version). It also generates text better than any other image generation model (though that&#x2019;s a low bar.)</p><p>Stable Diffusion XL is much more open to generating images of notable figures and well-known characters, though some of it&#x2019;s images of Mickey look like they were drawn while on some really fun drugs. However, it often messes up anatomy and object relationships. While you <em>can</em> ask it to generate text (and see it&#x2019;s trying its best), it falls way behind DALL-E 3 on that front.</p><p>With PromptPerfect we can get around some of these weaknesses from both models.

In a health study, you might want to know if some drug or treatment made recipients healthier, longer lived, or improved their condition in some way. But health and improved life quality are difficult things to measure directly, and it can take decades to find out if a treatment extended someone&#x2019;s life.</p><p>So researchers use proxies. In a health study, that might be something like physical strength, reduced pain, lowered blood pressure, or some other variable that you can easily measure. One of the problems with health research is that the proxy may not really be indicative of the better health outcome you want a drug or treatment to have.</p><p>A measurement is a proxy for something useful that matters to you. You may not be able to measure that thing, so you measure something else, something you <em>can</em> measure, that you have reasons to believe correlates with the useful thing you really care about.</p><p>Focusing on measurement was a major development of 20th century operational research and it&#x2019;s had some profound and positive effects. <a href="https://en.wikipedia.org/wiki/Total_quality_management?ref=jina-ai-gmbh.ghost.io">Total Quality Management</a>, a set of doctrines credited with Japan&#x2019;s rise to economic dominance in the 1980s, is almost completely about constant measurement of proxy variables and optimizing practices on that basis.</p><p>But a focus on measurement poses some known, big problems:</p><ul><li>A measurement may stop being a good proxy when you make decisions based on it.</li><li>There are often ways to inflate a measure that don&#x2019;t improve anything, leading to the possibility of cheating or believing you are making progress by doing things that aren&#x2019;t helping.</li></ul><p>Some people believe <a href="https://journals.plos.org/plosmedicine/article?id=10.1371%2Fjournal.pmed.0020124&amp;ref=jina-ai-gmbh.ghost.io">most medical research may be just wrong</a> in part because of this problem. The disconnect between things you can measure and actual goals is one of the reasons cited <a href="https://en.wikipedia.org/wiki/McNamara_fallacy?ref=jina-ai-gmbh.ghost.io">for the calamity of America&#x2019;s war in Vietnam</a>.</p><p>This is sometimes called the &#x201C;Streetlight Effect&#x201D;, from the stories, like the one at the top of this page, of the drunk looking for something not where he lost it, but where the light is better. A proxy measure is like looking where there&#x2019;s light because there&apos;s no light on the thing we want to see.</p><p>In more technical literature, the &#x201C;Streetlight Effect&#x201D; is typically tied to <a href="https://en.wikipedia.org/wiki/Goodhart%27s_law?ref=jina-ai-gmbh.ghost.io">Goodhart&#x2019;s Law</a>, attributed to British economist <a href="https://en.wikipedia.org/wiki/Charles_Goodhart?ref=jina-ai-gmbh.ghost.io">Charles Goodhart</a>&#x2019;s criticisms of the Thatcher government, which had placed a lot of emphasis on proxy measures of prosperity. Goodhart&#x2019;s Law has several formulations, but the one below is the most widely cited:</p><blockquote>[E]very measure which becomes a target becomes a bad measure[&#x2026;]<br><br><em>Keith Hoskins, 1996 The &apos;awful idea of accountability&apos;: inscribing people into the measurement of objects.</em>00s</blockquote><p>In AI, a famous example of this is the BLEU metric used in machine translation research. Developed in 2001 at IBM, BLEU is a way to automate the evaluation of machine translation systems, and it was a pivotal factor in the machine translation boom of the 00s. Once it was easy to give your system a score, you could work at improving it. And BLEU scores improved consistently. By 2010, it was nearly impossible to get a research paper on machine translation into a journal or conference if it didn&#x2019;t beat the state-of-the-art BLEU score, no matter how innovative the paper was nor how well it might handle some specific problem that other systems were handling poorly.</p><p>The easiest way to get into a conference was to find some minor way to fiddle with the parameters of your model, get a BLEU score fractionally higher than Google Translate&#x2019;s, and then submit. These results were essentially useless. Just getting some fresh texts for it to translate would show that they were rarely better and frequently worse than the state-of-the-art.</p><p>Instead of using BLEU to evaluate progress in machine translation, getting a better BLEU score became the goal. As soon as that happened, it stopped being a useful way to evaluate progress.</p><h2 id="are-our-ai-benchmarks-good-proxies">Are Our AI Benchmarks Good Proxies?</h2><p>The most widely used benchmark for embedding models is the MTEB test set, which consists of 56 specific tests. These are averaged by category and all together to produce a collection of class-specific scores. At the time of writing, the top of the MTEB leaderboard looks like this:</p><figure class="kg-card kg-image-card"><img src="https://jina-ai-gmbh.ghost.io/content/images/2024/05/Screenshot-2024-05-15-at-16.22.08.png" class="kg-image" alt="AIR-Bench: Better Metrics for Better Search Foundation" loading="lazy" width="1942" height="1454" srcset="https://jina-ai-gmbh.ghost.io/content/images/size/w600/2024/05/Screenshot-2024-05-15-at-16.22.08.png 600w, https://jina-ai-gmbh.ghost.io/content/images/size/w1000/2024/05/Screenshot-2024-05-15-at-16.22.08.png 1000w, https://jina-ai-gmbh.ghost.io/content/images/size/w1600/2024/05/Screenshot-2024-05-15-at-16.22.08.png 1600w, https://jina-ai-gmbh.ghost.io/content/images/2024/05/Screenshot-2024-05-15-at-16.22.08.png 1942w" sizes="(min-width: 720px) 720px"></figure><p>The top-ranked embedding model has an overall average score of 68.28, the next highest is 67.56. It&#x2019;s very difficult, looking at this table, to know if that&apos;s a big difference or not. If it&#x2019;s a small difference, then other factors may be more important than which model has the highest score:</p><ul><li><strong>Model size:</strong> Models have different sizes, reflecting different computing resource demands. Small models run faster, in less memory, and require less expensive hardware. We see, on this top 10 list, models ranging in size from 434 million parameters to over 46 billion &#x2014; a 100-fold difference!</li><li><strong>Embedding size:</strong> Embedding dimensions vary. Smaller dimensionality makes embedding vectors use less memory and storage and makes vector comparisons (the core use of embeddings) much faster. In this list, we see embedding dimensions from 768 to 4096 &#x2014; only a five-fold difference but still significant when building commercial applications.</li><li><strong>Context input window size:</strong> Context windows vary in both size and quality, from 2048 tokens to 32768. Furthermore, different models use different approaches to positional encoding and input management, which can create biases in favor of specific parts of the input.</li></ul><p>In short, the overall average is a very incomplete way to determine which embedding model is best.</p><p>Even if we look at task-specific scores, like those below for retrieval, we face the same problems all over again. No matter what a model&#x2019;s score is on this set of tests, there is no way to know what models will perform best for your particular unique use case.</p><figure class="kg-card kg-image-card"><img src="https://jina-ai-gmbh.ghost.io/content/images/2024/05/Screenshot-2024-05-15-at-16.52.31.png" class="kg-image" alt="AIR-Bench: Better Metrics for Better Search Foundation" loading="lazy" width="2000" height="1324" srcset="https://jina-ai-gmbh.ghost.io/content/images/size/w600/2024/05/Screenshot-2024-05-15-at-16.52.31.png 600w, https://jina-ai-gmbh.ghost.io/content/images/size/w1000/2024/05/Screenshot-2024-05-15-at-16.52.31.png 1000w, https://jina-ai-gmbh.ghost.io/content/images/size/w1600/2024/05/Screenshot-2024-05-15-at-16.52.31.png 1600w, https://jina-ai-gmbh.ghost.io/content/images/2024/05/Screenshot-2024-05-15-at-16.52.31.png 2000w" sizes="(min-width: 720px) 720px"></figure><p>But that&#x2019;s not the end of the problems with these kinds of benchmarks.</p><p>The main insight of Goodhart&#x2019;s Law is that a metric can always be gamed, often without intending to. For example, MTEB benchmarks consist of data from public sources that are likely to be in your training data. Unless you specifically work to try to remove benchmarking data from your training, your benchmark scores will be statistically unsound.</p><p>There is no simple, comprehensive solution. A benchmark is a proxy and we can never be certain it reflects what we want to know but can&#x2019;t directly measure.</p><p>But we do see three core problems with AI benchmarks that we can mitigate:</p><ol><li>Benchmarks are fixed in nature: The same tasks, using the same texts.</li><li>Benchmarks are generic: They are not very informative about real scenarios.</li><li>Benchmarks are inflexible: They cannot respond to diverse use cases.</li></ol><p>AI creates problems like this, but it sometimes also creates solutions. We believe we can use AI models to address these issues, at least as they affect AI benchmarks.</p><h2 id="using-ai-to-benchmark-ai-air-bench">Using AI to Benchmark AI: AIR-Bench</h2><p>AIR-Bench is open source and available under the <a href="https://opensource.org/license/mit?ref=jina-ai-gmbh.ghost.io" rel="noopener noreferrer">MIT License</a>.

However, between the increasing size of models and the growing quantities of data AI models process, the computational and storage demands for traditional embeddings have escalated. Binary embeddings have been introduced as a compact, efficient alternative that maintains high performance while drastically reducing resource requirements.</p><p>Binary embeddings are one way to mitigate these resource requirements by reducing the size of embedding vectors by as much as 96% (96.875% in the case of Jina Embeddings). Users can leverage the power of compact binary embeddings within their AI applications with minimal loss of accuracy.</p><h2 id="what-are-binary-embeddings">What Are Binary Embeddings?</h2><p>Binary embeddings are a specialized form of data representation where traditional high-dimensional floating-point vectors are transformed into binary vectors. This not only compresses the embeddings but also retains nearly all of the vectors&apos; integrity and utility. The essence of this technique lies in its ability to maintain the semantics and relational distances between the data points even after conversion.<br><br>The magic behind binary embeddings is quantization, a method that turns high-precision numbers into lower-precision ones. In AI modeling, this often means converting the 32-bit floating-point numbers in embeddings into representations with fewer bits, like 8-bit integers.</p><figure class="kg-card kg-image-card kg-card-hascaption"><img src="https://jina-ai-gmbh.ghost.io/content/images/2024/04/be.jpeg" class="kg-image" alt="Binary Embeddings: All the AI, 3.125% of the Fat" loading="lazy" width="1280" height="860" srcset="https://jina-ai-gmbh.ghost.io/content/images/size/w600/2024/04/be.jpeg 600w, https://jina-ai-gmbh.ghost.io/content/images/size/w1000/2024/04/be.jpeg 1000w, https://jina-ai-gmbh.ghost.io/content/images/2024/04/be.jpeg 1280w" sizes="(min-width: 720px) 720px"><figcaption><span style="white-space: pre-wrap;">Binarization is the transformation of all scalar values to 0 or 1, like converting a color image to one with just black or white pixels.

Transforming 32-bit floating point numbers to binary digits cuts the size of embedding vectors 32-fold, a reduction of 96.875%. Vector operations on the resulting embeddings are much faster as a result. Using hardware speed-ups available on some microchips can increase the speed of vector comparisons by much more than 32-fold when the vectors are binarized.</p><p>Some information is inevitably lost during this process, but this loss is minimized when the model is very performant. If the non-quantized embeddings of different things are maximally different, then binarization is more likely to preserve that difference well. Otherwise, it can be difficult to interpret the embeddings correctly.</p><p>Jina Embeddings models are trained to be very robust in exactly that way, making them well-suited to binarization.</p><p>Such compact embeddings make new AI applications possible, particularly in resource-constrained contexts like mobile and time-sensitive uses.</p><p>These cost and computing time benefits come at a relatively small performance cost, as the chart below shows.</p><figure class="kg-card kg-image-card kg-card-hascaption"><img src="https://hackmd.io/_uploads/ByhwJsQWC.png" class="kg-image" alt="Binary Embeddings: All the AI, 3.125% of the Fat" loading="lazy" width="1686" height="1050"><figcaption><i><em class="italic" style="white-space: pre-wrap;">NDCG@10: Scores calculated using </em></i><a href="https://en.wikipedia.org/wiki/Discounted_cumulative_gain?ref=jina-ai-gmbh.ghost.io"><i><em class="italic" style="white-space: pre-wrap;">Normalized Discounted Cumulative Gain</em></i></a><i><em class="italic" style="white-space: pre-wrap;"> for the top 10 results.</em></i></figcaption></figure><p>For <code>jina-embeddings-v2-base-en</code>, binary quantization reduces retrieval accuracy from 47.13% to 42.05%, a loss of approximately 10%. For <code>jina-embeddings-v2-base-de</code>, this loss is only 4%, from 44.39% to 42.65%.</p><p>Jina Embeddings models perform so well when producing binary vectors because they are trained to create a more uniform distribution of embeddings. This means that two different embeddings will likely be further from each other in more dimensions than embeddings from other models. This property ensures that those distances are better represented by their binary forms.</p><h2 id="how-do-binary-embeddings-work">How Do Binary Embeddings Work?</h2><p>To see how this works, consider three embeddings: <em>A</em>, <em>B</em>, and <em>C</em>. These three are all full floating-point vectors, not binarized ones. Now, let&#x2019;s say the distance from <em>A</em> to <em>B</em> is greater than the distance from <em>B</em> to <em>C</em>. With embeddings, we typically use the <a href="https://en.wikipedia.org/wiki/Cosine_similarity?ref=jina-ai-gmbh.ghost.io">cosine distance</a>, so:</p><figure class="kg-card kg-image-card"><img src="https://jina-ai-gmbh.ghost.io/content/images/2024/05/image-9.png" class="kg-image" alt="Binary Embeddings: All the AI, 3.125% of the Fat" loading="lazy" width="172" height="19"></figure><p>If we binarize <em>A</em>, <em>B</em>, and <em>C</em>, we can measure distance more efficiently with <a href="https://en.wikipedia.org/wiki/Hamming_distance?ref=jina-ai-gmbh.ghost.io">Hamming distance</a>.</p><figure class="kg-card kg-image-card kg-card-hascaption"><img src="https://jina-ai-gmbh.ghost.io/content/images/2024/05/image-6.png" class="kg-image" alt="Binary Embeddings: All the AI, 3.125% of the Fat" loading="lazy" width="2000" height="808" srcset="https://jina-ai-gmbh.ghost.io/content/images/size/w600/2024/05/image-6.png 600w, https://jina-ai-gmbh.ghost.io/content/images/size/w1000/2024/05/image-6.png 1000w, https://jina-ai-gmbh.ghost.io/content/images/size/w1600/2024/05/image-6.png 1600w, https://jina-ai-gmbh.ghost.io/content/images/size/w2400/2024/05/image-6.png 2400w" sizes="(min-width: 720px) 720px"><figcaption><span style="white-space: pre-wrap;">Hamming Distance on a cube.

<p>For binary vectors, if the cosine distance between <em>A<sub>bin</sub></em> and <em>B<sub>bin</sub></em> is greater than between <em>B<sub>bin</sub></em> and <em>C<sub>bin</sub></em>, then the Hamming distance between <em>A<sub>bin</sub></em> and <em>B<sub>bin</sub></em> is greater than or equal to the Hamming distance between <em>B<sub>bin</sub></em> and <em>C<sub>bin</sub></em>.</p>
<p>So if:</p><figure class="kg-card kg-image-card"><img src="https://jina-ai-gmbh.ghost.io/content/images/2024/05/image-10.png" class="kg-image" alt="Binary Embeddings: All the AI, 3.125% of the Fat" loading="lazy" width="172" height="19"></figure><p>then for Hamming distances:</p><figure class="kg-card kg-image-card"><img src="https://jina-ai-gmbh.ghost.io/content/images/2024/05/image-11.png" class="kg-image" alt="Binary Embeddings: All the AI, 3.125% of the Fat" loading="lazy" width="296" height="19"></figure><p>Ideally, when we binarize embeddings, we want the same relationships with full embeddings to hold for the binary embeddings as for the full ones. This means that if one distance is greater than another for floating point cosine, it should be greater for the Hamming distance between their binarized equivalents:</p><figure class="kg-card kg-image-card"><img src="https://jina-ai-gmbh.ghost.io/content/images/2024/05/image-12.png" class="kg-image" alt="Binary Embeddings: All the AI, 3.125% of the Fat" loading="lazy" width="518" height="19"></figure><p>We can&#x2019;t make this true for all triplets of embeddings, but we can make it true for almost all of them.</p><figure class="kg-card kg-image-card kg-card-hascaption"><img src="https://jina-ai-gmbh.ghost.io/content/images/2024/05/image-8.png" class="kg-image" alt="Binary Embeddings: All the AI, 3.125% of the Fat" loading="lazy" width="1500" height="1184" srcset="https://jina-ai-gmbh.ghost.io/content/images/size/w600/2024/05/image-8.png 600w, https://jina-ai-gmbh.ghost.io/content/images/size/w1000/2024/05/image-8.png 1000w, https://jina-ai-gmbh.ghost.io/content/images/2024/05/image-8.png 1500w" sizes="(min-width: 720px) 720px"><figcaption><span style="white-space: pre-wrap;">The blue dots correspond to full floating-point vectors and the red ones to their binarized equivalents. </span></figcaption></figure><p>With a binary vector, we can treat every dimension as either present (a one) or absent (a zero). The more distant two vectors are from each other in non-binary form, the higher the probability that in any one dimension, one will have a positive value and the other a negative value. This means that in binary form, there will most likely be more dimensions where one has a zero and the other a one. This makes them further apart by Hamming distance.</p><p>The opposite applies to vectors that are closer together: The closer the non-binary vectors are, the higher the probability that in any dimension both have zeros or both have ones. This makes them closer by Hamming distance.</p><p>Jina Embeddings models are so well-suited to binarization because we train them using negative mining and other fine-tuning practices to especially increase the distance between dissimilar things and reduce the distance between similar ones. This makes the embeddings more robust, more sensitive to similarities and differences, and makes the Hamming distance between binary embeddings more proportionate to the cosine distance between non-binary ones.</p><h2 id="how-much-can-i-save-with-jina-ais-binary-embeddings">How Much Can I Save with Jina AI&apos;s Binary Embeddings?</h2><p>Embracing Jina AI&#x2019;s binary embedding models doesn&apos;t just lower latency in time-sensitive applications, but also yields considerable cost benefits, as shown in the table below:</p>

Since its first release on April 15th, we have served over <strong>18 million requests</strong> from the world, suggesting its popularity.</p><p>Today we are excited to move the needle further by introducing the search grounding API <code>https://s.jina.ai</code>.

<h2 id="conclusion">Conclusion</h2><p>We believe grounding is essential for GenAI applications, and building grounded solutions should be easy for everyone. That&apos;s why we introduced the new search grounding endpoint, <code>s.jina.ai</code>, which allows developers to easily incorporate world knowledge into their GenAI applications. We want developers to establish user trust, provide explainable answers, and inspire curiosity in millions of users.</p>]]></content:encoded></item><item><title><![CDATA[Albus by Springworks: Empowering Employees with Enterprise Search]]></title><description><![CDATA[Learn how a leading HR-tech startup uses Jina AI’s models to talk with structured and unstructured data.]]></description><link>https://jina.ai/news/albus-by-springworks-empowering-employees-with-enterprise-search/</link><guid isPermaLink="false">663a0e18af8f52000115bef2</guid><category><![CDATA[Tech Blog]]></category><dc:creator><![CDATA[Francesco Kruk]]></dc:creator><pubDate>Mon, 13 May 2024 09:00:14 GMT</pubDate><media:content url="https://jina-ai-gmbh.ghost.io/content/images/2024/05/19.jpg" medium="image"/><content:encoded><![CDATA[<img src="https://jina-ai-gmbh.ghost.io/content/images/2024/05/19.jpg" alt="Albus by Springworks: Empowering Employees with Enterprise Search"><p></p><p>The advent of Large Language Models (LLMs) and Retrieval Augmented Generation (RAG) has opened up many avenues for companies to leverage their data, but also poses the problem of connecting different sources to a single communication interface.

Employees often have to search endlessly for information they remember reading somewhere, but cannot find again, such as results from a past brainstorming session or minutes of a sprint planning from the previous week. This fragmentation of information creates barriers that decrease productivity and add to frustration. Generative AI promises to address this issue, creating question-answering systems with access to multi-source data, so employees have a single source for answers. To do this, we need an AI application that can access all these information silos and integrate them.</p><h2 id="springworks-albus-to-the-rescue">Springworks Albus to the Rescue</h2><p>Albus integrates with <a href="https://www.springworks.in/albus/integrations/?ref=jina-ai-gmbh.ghost.io"><u>100+ commonly used workplace applications</u></a>, including CRMs, ticketing systems, human resource management systems, and knowledge management tools. By leveraging Jina AI&#x2019;s state-of-the-art Embedding and Reranker models with an LLM for generating answers, Albus answers employees&apos; questions after analyzing all connected sources and using the most relevant and up-to-date information. Employees no longer need to search in multiple apps or remember specific file names and locations.</p><blockquote>&#x201C;<em>We&#x2019;ve evaluated almost all state-of-the-art embeddings and reranker models on our hand-crafted company-internal benchmarks, and Jina&#x2019;s models truly stand out.

Albus retrieves both structured and unstructured data.

Each oral session lasts no longer than 45 minutes, which is just right&#x2014;not too overwhelming. Most importantly, these oral sessions don&#x2019;t overlap with the poster sessions. This setup eliminates the FOMO that you might feel while exploring the posters.

I recall discussions last summer about the future direction of LLM-agents inside our team: whether to develop one god-like agent capable of using thousands of tools, similar to the original AutoGPT/BabyAGI model, or to create thousands of mediocre agents that work together to achieve something greater, similar to Stanford&apos;s virtual town. Last fall, my colleague Florian Hoenicke made a significant contribution to the multi-agent direction by developing a virtual environment in PromptPerfect.

I had a conversation with a core contributor of <a href="https://github.com/microsoft/autogen?ref=jina-ai-gmbh.ghost.io">AutoGen from Microsoft</a>, who explained that multi-agent role-playing offers a more general framework. Interestingly, he noted that having a single agent utilize multiple tools can also be implemented easily within this framework. <a href="https://t.co/LkYqDqMTld?ref=jina-ai-gmbh.ghost.io">MetaGPT is another excellent example</a>, inspired by the classic Standard Operating Procedures (SOPs) used in business.

Most of them operate on turn-based, sequential systems, which tend to be slow. In these systems, one agent begins to &quot;think&quot; only <em>after</em> the previous one has finished &quot;talking.&quot; This sequential process doesn&apos;t mirror how interactions happen in the real world, where people think, speak, and listen simultaneously. Real-world conversations are dynamic; individuals can interrupt each other, moving the conversation forward rapidly&#x2014;it&apos;s an asynchronous streaming process, making it highly efficient.</p><p>An ideal multi-agent framework should embrace asynchronous communication, allow interruptions, and prioritize streaming capabilities as foundational elements. This would enable all agents to work together seamlessly with a fast inference backend like <a href="https://groq.com/?ref=jina-ai-gmbh.ghost.io">Groq</a>. By implementing a multi-agent system with high throughput, we could significantly enhance the user experience and unlock many new possibilities.</p><h3 id="gpt-4-is-too-smart-to-be-safe-stealthy-chat-with-llms-via-cipher">GPT-4 Is Too Smart To Be Safe: Stealthy Chat with LLMs via Cipher</h3><figure class="kg-card kg-image-card"><img src="https://jina-ai-gmbh.ghost.io/content/images/2024/05/image.png" class="kg-image" alt="What&apos;s Interesting in ICLR2024" loading="lazy" width="938" height="1186" srcset="https://jina-ai-gmbh.ghost.io/content/images/size/w600/2024/05/image.png 600w, https://jina-ai-gmbh.ghost.io/content/images/2024/05/image.png 938w" sizes="(min-width: 720px) 720px"></figure><figure class="kg-card kg-bookmark-card"><a class="kg-bookmark-container" href="https://arxiv.org/abs/2308.06463?ref=jina-ai-gmbh.ghost.io"><div class="kg-bookmark-content"><div class="kg-bookmark-title">GPT-4 Is Too Smart To Be Safe: Stealthy Chat with LLMs via Cipher</div><div class="kg-bookmark-description">Safety lies at the core of the development of Large Language Models (LLMs).

We propose a novel framework CipherChat to systematically examine the generalizability of safety alignment to non-natural languages -- ciphers. CipherChat enables humans to chat with LLMs through cipher prompts topped with system role descriptions and few-shot enciphered demonstrations. We use CipherChat to assess state-of-the-art LLMs, including ChatGPT and GPT-4 for different representative human ciphers across 11 safety domains in both English and Chinese. Experimental results show that certain ciphers succeed almost 100% of the time to bypass the safety alignment of GPT-4 in several safety domains, demonstrating the necessity of developing safety alignment for non-natural languages. Notably, we identify that LLMs seem to have a &#x2033;secret cipher&#x2033;, and propose a novel SelfCipher that uses only role play and several demonstrations in natural language to evoke this capability. SelfCipher surprisingly outperforms existing human ciphers in almost all cases.

Although several preventive measures have been developed to mitigate the potential risks associated with LLMs, they have primarily focused on English. In this study, we reveal the presence of multilingual jailbreak challenges within LLMs and consider two potential risky scenarios: unintentional and intentional. The unintentional scenario involves users querying LLMs using non-English prompts and inadvertently bypassing the safety mechanisms, while the intentional scenario concerns malicious users combining malicious instructions with multilingual prompts to deliberately attack LLMs. The experimental results reveal that in the unintentional scenario, the rate of unsafe content increases as the availability of languages decreases. Specifically, low-resource languages exhibit about three times the likelihood of encountering harmful content compared to high-resource languages, with both ChatGPT and GPT-4. In the intentional scenario, multilingual prompts can exacerbate the negative impact of malicious instructions, with astonishingly high rates of unsafe output: 80.92\% for ChatGPT and 40.71\% for GPT-4. To handle such a challenge in the multilingual context, we propose a novel \textsc{Self-Defense} framework that automatically generates multilingual training data for safety fine-tuning. Experimental results show that ChatGPT fine-tuned with such data can achieve a substantial reduction in unsafe content generation.

To automate this process, in this paper, we propose a novel framework for discrete prompt optimization, called EvoPrompt, which borrows the idea of evolutionary algorithms (EAs) as they exhibit good performance and fast convergence. To enable EAs to work on discrete prompts, which are natural language expressions that need to be coherent and human-readable, we connect LLMs with EAs. This approach allows us to simultaneously leverage the powerful language processing capabilities of LLMs and the efficient optimization performance of EAs. Specifically, abstaining from any gradients or parameters, EvoPrompt starts from a population of prompts and iteratively generates new prompts with LLMs based on the evolutionary operators, improving the population based on the development set. We optimize prompts for both closed- and open-source LLMs including GPT-3.5 and Alpaca, on 31 datasets covering language understanding, generation tasks, as well as BIG-Bench Hard (BBH) tasks. EvoPrompt significantly outperforms human-engineered prompts and existing methods for automatic prompt generation (e.g., up to 25% on BBH). Furthermore, EvoPrompt demonstrates that connecting LLMs with EAs creates synergies, which could inspire further research on the combination of LLMs and conventional algorithms.</div><div class="kg-bookmark-metadata"><img class="kg-bookmark-icon" src="https://arxiv.org/static/browse/0.3.4/images/icons/apple-touch-icon.png" alt="What&apos;s Interesting in ICLR2024"><span class="kg-bookmark-author">arXiv.org</span><span class="kg-bookmark-publisher">Qingyan Guo</span></div></div><div class="kg-bookmark-thumbnail"><img src="https://arxiv.org/static/browse/0.3.4/images/arxiv-logo-fb.png" alt="What&apos;s Interesting in ICLR2024"></div></a></figure><p>Another presentation that caught my attention introduced an instruction tuning algorithm inspired by the classic genetic evolution algorithm.

While the field of CausalNLP has attracted much interest in the recent years, existing causal inference datasets in NLP primarily rely on discovering causality from empirical knowledge (e.g., commonsense knowledge). In this work, we propose the first benchmark dataset to test the pure causal inference skills of large language models (LLMs). Specifically, we formulate a novel task Corr2Cause, which takes a set of correlational statements and determines the causal relationship between the variables. We curate a large-scale dataset of more than 200K samples, on which we evaluate seventeen existing LLMs. Through our experiments, we identify a key shortcoming of LLMs in terms of their causal inference skills, and show that these models achieve almost close to random performance on the task. This shortcoming is somewhat mitigated when we try to re-purpose LLMs for this skill via finetuning, but we find that these models still fail to generalize -- they can only perform causal inference in in-distribution settings when variable names and textual expressions used in the queries are similar to those in the training set, but fail in out-of-distribution settings generated by perturbing these queries. Corr2Cause is a challenging task for LLMs, and would be helpful in guiding future research on improving LLMs&#x2019; pure reasoning skills and generalizability.

An idempotent operator is one that can be applied sequentially without changing the result beyond the initial application, namely $f(f(z))=f(z)$. The proposed model $f$ is trained to map a source distribution (e.g, Gaussian noise) to a target distribution (e.g. realistic images) using the following objectives: (1) Instances from the target distribution should map to themselves, namely $f(x)=x$. We define the target manifold as the set of all instances that $f$ maps to themselves. (2) Instances that form the source distribution should map onto the defined target manifold. This is achieved by optimizing the idempotence term, $f(f(z))=f(z)$ which encourages the range of $f(z)$ to be on the target manifold. Under ideal assumptions such a process provably converges to the target distribution. This strategy results in a model capable of generating an output in one step, maintaining a consistent latent space, while also allowing sequential applications for refinement. Additionally, we find that by processing inputs from both target and source distributions, the model adeptly projects corrupted or modified data back to the target manifold. This work is a first step towards a ``global projector&#x2033; that enables projecting any input into a target data distribution.</div><div class="kg-bookmark-metadata"><img class="kg-bookmark-icon" src="https://arxiv.org/static/browse/0.3.4/images/icons/apple-touch-icon.png" alt="What&apos;s Interesting in ICLR2024"><span class="kg-bookmark-author">arXiv.org</span><span class="kg-bookmark-publisher">Assaf Shocher</span></div></div><div class="kg-bookmark-thumbnail"><img src="https://arxiv.org/static/browse/0.3.4/images/arxiv-logo-fb.png" alt="What&apos;s Interesting in ICLR2024"></div></a></figure><figure class="kg-card kg-bookmark-card"><a class="kg-bookmark-container" href="https://arxiv.org/abs/2401.12970?ref=jina-ai-gmbh.ghost.io"><div class="kg-bookmark-content"><div class="kg-bookmark-title">Raidar: geneRative AI Detection viA Rewriting</div><div class="kg-bookmark-description">We find that large language models (LLMs) are more likely to modify human-written text than AI-generated text when tasked with rewriting.

FVs are robust to changes in context, i.e., they trigger execution of the task on inputs such as zero-shot and natural text settings that do not resemble the ICL contexts from which they are collected. We test FVs across a range of tasks, models, and layers and find strong causal effects across settings in middle layers. We investigate the internal structure of FVs and find while that they often contain information that encodes the output space of the function, this information alone is not sufficient to reconstruct an FV. Finally, we test semantic vector composition in FVs, and find that to some extent they can be summed to create vectors that trigger new complex tasks. Our findings show that compact, causal internal vector representations of function abstractions can be explicitly extracted from LLMs. Our code and data are available at https://functions.baulab.info.</div><div class="kg-bookmark-metadata"><img class="kg-bookmark-icon" src="https://arxiv.org/static/browse/0.3.4/images/icons/apple-touch-icon.png" alt="What&apos;s Interesting in ICLR2024"><span class="kg-bookmark-author">arXiv.org</span><span class="kg-bookmark-publisher">Eric Todd</span></div></div><div class="kg-bookmark-thumbnail"><img src="https://arxiv.org/static/browse/0.3.4/images/arxiv-logo-fb.png" alt="What&apos;s Interesting in ICLR2024"></div></a></figure><p>In-context learning (ICL) can prompt function-like behaviors in LLMs, but the mechanics of how LLMs encapsulate an ICL task are less understood.

Deterministic functions are not sufficiently powerful to capture ambiguity, prompting the exploration of probabilistic embeddings to tackle the challenge. However, the existing probabilistic ITM approach encounters two key shortcomings; the burden of heavy computations due to the Monte Carlo approximation, and the loss saturation issue in the face of abundant false negatives. To overcome the issues, this paper presents an improved Probabilistic Cross-Modal Embeddings (named PCME++) by introducing a new probabilistic distance with a closed-form solution. In addition, two optimization techniques are proposed to enhance PCME++ further: first, the incorporation of pseudo-positives to prevent the negative effect under massive false negatives; second, mixed sample data augmentation for probabilistic matching. Experimental results on MS-COCO Caption and two extended benchmarks, CxC and ECCV Caption, demonstrate the effectiveness of PCME++ compared to state-of-the-art ITM methods. The robustness of PCME++ is also evaluated under noisy image-text correspondences. In addition, the potential applicability of PCME++ in automatic prompt-filtering for zero-shot classification is shown.

Existing approaches perform k-NN search with CE by approximating the CE similarity with a vector embedding space fit either with dual-encoders (DE) or CUR matrix factorization. DE-based retrieve-and-rerank approaches suffer from poor recall on new domains and the retrieval with DE is decoupled from the CE. While CUR-based approaches can be more accurate than the DE-based approach, they require a prohibitively large number of CE calls to compute item embeddings, thus making it impractical for deployment at scale. In this paper, we address these shortcomings with our proposed sparse-matrix factorization based method that efficiently computes latent query and item embeddings to approximate CE scores and performs k-NN search with the approximate CE similarity. We compute item embeddings offline by factorizing a sparse matrix containing query-item CE scores for a set of train queries. Our method produces a high-quality approximation while requiring only a fraction of CE calls as compared to CUR-based methods, and allows for leveraging DE to initialize the embedding space while avoiding compute- and resource-intensive finetuning of DE via distillation. At test time, the item embeddings remain fixed and retrieval occurs over rounds, alternating between a) estimating the test query embedding by minimizing error in approximating CE scores of items retrieved thus far, and b) using the updated test query embedding for retrieving more items. Our k-NN search method improves recall by up to 5% (k=1) and 54% (k=100) over DE-based approaches. Additionally, our indexing approach achieves a speedup of up to 100x over CUR-based and 5x over DE distillation methods, while matching or improving k-NN search recall over baselines.</div><div class="kg-bookmark-metadata"><img class="kg-bookmark-icon" src="https://arxiv.org/static/browse/0.3.4/images/icons/apple-touch-icon.png" alt="What&apos;s Interesting in ICLR2024"><span class="kg-bookmark-author">arXiv.org</span><span class="kg-bookmark-publisher">Nishant Yadav</span></div></div><div class="kg-bookmark-thumbnail"><img src="https://arxiv.org/static/browse/0.3.4/images/arxiv-logo-fb.png" alt="What&apos;s Interesting in ICLR2024"></div></a></figure><p>A faster reranker implementation was discussed that shows potential to scale effectively on full datasets, possibly eliminating the need for a vector database.

One issue that plagues the Triplet Loss is network collapse, an undesirable phenomenon where the network projects the embeddings of all data onto a single point. Researchers predominately solve this problem by using triplet mining strategies. While hard negative mining is the most effective of these strategies, existing formulations lack strong theoretical justification for their empirical success. In this paper, we utilize the mathematical theory of isometric approximation to show an equivalence between the Triplet Loss sampled by hard negative mining and an optimization problem that minimizes a Hausdorff-like distance between the neural network and its ideal counterpart function. This provides the theoretical justifications for hard negative mining&#x2019;s empirical efficacy.

In addition, we demonstrate that our tokenizer surpasses the previously top-performing video tokenizer on two more tasks: (1) video compression comparable to the next-generation video codec (VCC) according to human evaluations, and (2) learning effective representations for action recognition tasks.</div><div class="kg-bookmark-metadata"><img class="kg-bookmark-icon" src="https://arxiv.org/static/browse/0.3.4/images/icons/apple-touch-icon.png" alt="What&apos;s Interesting in ICLR2024"><span class="kg-bookmark-author">arXiv.org</span><span class="kg-bookmark-publisher">Lijun Yu</span></div></div><div class="kg-bookmark-thumbnail"><img src="https://arxiv.org/static/browse/0.3.4/images/arxiv-logo-fb.png" alt="What&apos;s Interesting in ICLR2024"></div></a></figure><h4 id="transformer-vq-linear-time-transformers-via-vector-quantization">Transformer-VQ: Linear-Time Transformers via Vector Quantization </h4><figure class="kg-card kg-image-card"><img src="https://pbs.twimg.com/media/GNKRnc8WQAAECJ2?format=jpg&amp;name=4096x4096" class="kg-image" alt="What&apos;s Interesting in ICLR2024" loading="lazy" width="4032" height="3024"></figure><figure class="kg-card kg-bookmark-card"><a class="kg-bookmark-container" href="https://arxiv.org/abs/2309.16354?ref=jina-ai-gmbh.ghost.io"><div class="kg-bookmark-content"><div class="kg-bookmark-title">Transformer-VQ: Linear-Time Transformers via Vector Quantization</div><div class="kg-bookmark-description">We introduce Transformer-VQ, a decoder-only transformer computing softmax-based dense self-attention in linear time. Transformer-VQ&#x2019;s efficient attention is enabled by vector-quantized keys and a novel caching mechanism.

In addition, the optimized implementation of Transformer-VQ is over 3x faster than a comparable quadratic-time transformer at sequence length 8k, is over 12x faster at 32k, and can scale to 131k with similar throughput.

Some of the blame belongs to the way <a href="https://jina.ai/news/artificial-general-intelligence-is-cursed-and-science-fiction-isnt-helping?ref=jina-ai-gmbh.ghost.io">apocalyptic science fiction</a> has created our mental picture of artificial intelligence. Visions of smart machines that can make more machines have been a common trope in science fiction for generations.</p><p>Plenty of people have been vocal about existential risks from recent developments in AI, many of them <a href="https://www.nytimes.com/2023/05/30/technology/ai-threat-warning.html?ref=jina-ai-gmbh.ghost.io">business leaders involved in commercializing AI</a>, and even a few <a href="https://www.reuters.com/technology/ai-pioneer-says-its-threat-world-may-be-more-urgent-than-climate-change-2023-05-05/?ref=jina-ai-gmbh.ghost.io">scientists</a> and <a href="https://www.lemonde.fr/en/international/article/2023/06/04/in-montreal-one-of-the-fathers-of-artificial-intelligence-warns-of-an-existential-threat-to-mankind_6029007_4.html?ref=jina-ai-gmbh.ghost.io">researchers</a>. It&#x2019;s become a component of AI hype: Something powerful enough to make sober-seeming icons of science and industry contemplate the end of the world must surely be powerful enough to turn a profit, right?</p><p>So, should we be worried about existential risks from AI? Do we need to fear that Sam Altman will make Ultron out of ChatGPT and have its <a href="https://youtu.be/d4yZPjB7smU?ref=jina-ai-gmbh.ghost.io">AI army throw Eastern European cities at us</a>? Should we be concerned about <a href="https://venturebeat.com/business/why-palantir-is-silicon-valleys-most-questionable-unicorn/?ref=jina-ai-gmbh.ghost.io">Peter Thiel&#x2019;s Palantir</a> <a href="https://youtu.be/4DQsG3TKQ0I?ref=jina-ai-gmbh.ghost.io">building Skynet</a> and sending <a href="https://youtu.be/wOO9DSnLOm8?ref=jina-ai-gmbh.ghost.io">robots with inexplicable Austrian accents back in time to kill us</a>?</p><p>Probably not. Industry leaders have yet to identify any clear way to make AI pay its own bills, much less disrupt industries, and even less threaten humanity at a level comparable to climate change or nuclear arms.</p><p>The AI models we actually have are hardly up to wiping out humanity. They struggle to draw hands, can&#x2019;t count more than three things, think it&apos;s <a href="https://www.nbcnewyork.com/news/local/nycs-ai-chatbot-was-caught-telling-businesses-to-break-the-law-the-city-isnt-taking-it-down/5287713/?ref=jina-ai-gmbh.ghost.io">okay to sell people cheese that rats have nibbled on</a>, and <a href="https://www.techtimes.com/articles/304222/20240502/ai-priest-demoted-saying-babies-baptized-gatorade.htm?ref=jina-ai-gmbh.ghost.io">perform Catholic baptisms with Gatorade</a>. The mundane, non-existential risks of AI &#x2014; the way the technology can help misinform, harass, generate spam, and be poorly used by people who are unclear about its limitations &#x2014; are worrying enough.</p><p>But one existential risk from artificial intelligence is definitely legitimate: AI poses a clear and present danger to&#x2026; <em>AI</em>.</p><p>This fear is usually called &#x201C;model collapse&#x201D; and it&#x2019;s received strong empirical demonstration in <a href="https://arxiv.org/abs/2305.17493?ref=jina-ai-gmbh.ghost.io">Shumailov et al.

The idea is simple: If you train AI models from AI-generated data, then take the resulting AI and use its output to train another model, repeating the process over multiple generations, the AI will get objectively worse and worse.

Will generative AI spam up the works and stifle its own progress? Or will AI help us make better AI? Or both?</p><p>We&#x2019;ll try to get some answers in this article.</p><h2 id="model-collapse">Model Collapse</h2><p>As much as we love Alemohammad et al. for inventing the term &#x201C;Model Autophagy Disorder (MAD)&#x201D;, &#x201C;model collapse&#x201D; is much catchier and doesn&#x2019;t involve Greek words for self-cannibalism. The metaphor of making photocopies of photocopies communicates the problem in simple terms, but there is a bit more to the underlying theory.</p><p>Training an AI model is a type of statistical modeling, an extension of what statisticians and data scientists have been doing for a long time. But, on Day One of data science class, you learn the data scientist&#x2019;s motto:</p><blockquote><strong><em>All models are wrong</em></strong>,&#xA0;<strong><em>but some are useful.</em></strong></blockquote><p>This quote, attributed to <a href="https://en.wikipedia.org/wiki/George_E._P._Box?ref=jina-ai-gmbh.ghost.io">George Box</a>, is the flashing red light that should be on top of every AI model. You can always make a statistical model for any data, and that model will always give you an answer, but absolutely nothing guarantees that that answer is right or even close to right.</p><p>A statistical model is an <em>approximation</em> of something. Its outputs may be useful, they might even be good enough, but they are still approximations. Even if you have a well-validated model that, on average, is very accurate, it can and probably will still make big mistakes sometimes.</p><p>AI models inherit all the problems of statistical modeling. Anyone who&#x2019;s played with ChatGPT or any other large AI model has seen it make mistakes.</p><p>So, if an AI model is an approximation of something real, an AI model trained on output from another AI model is an approximation of an approximation. The errors accumulate, and it inherently has to be a less correct model than the model it was trained from.</p><p>Alemohammad et al. show that you can&#x2019;t fix the problem by adding some of the original training data to the AI output before training the new &#x201C;child&#x201D; model. That only slows model collapse, it can&#x2019;t stop it. Unless you introduce enough new, previously unseen, real-world data whenever training with AI output, model collapse is inevitable.</p><p>How much new data is enough depends on difficult-to-predict, case-specific factors, but more new, real data and less AI-generated data is always better than the opposite.</p><p>And that&#x2019;s a problem because all the readily accessible sources of fresh human-made data are already tapped out while the amount of AI-generated image and text data out there is growing by leaps and bounds. The ratio of human-made to AI-made content on the Internet is falling, possibly falling fast. There is no <a href="https://www.washingtonpost.com/technology/2023/06/02/turnitin-ai-cheating-detector-accuracy/?ref=jina-ai-gmbh.ghost.io" rel="noreferrer">reliable way to automatically detect AI-generated data</a> and <a href="https://arxiv.org/abs/2303.11156?ref=jina-ai-gmbh.ghost.io">many researchers</a> <a href="https://www.techspot.com/news/98031-reliable-detection-ai-generated-text-impossible-new-study.html?ref=jina-ai-gmbh.ghost.io">believe there can&#x2019;t be one.</a> Public access to AI image and text generation models ensures that this problem will grow, probably grow dramatically, and has no obvious solution.</p><p>The <a href="https://www.vice.com/en/article/y3w4gw/a-shocking-amount-of-the-web-is-already-ai-translated-trash-scientists-determine?ref=jina-ai-gmbh.ghost.io" rel="noreferrer">amount of machine translation on the Internet</a> might mean it&#x2019;s already too late. Machine-translated text on the Internet has been polluting our data sources for years, since long before the generative AI revolution. According to <a href="https://arxiv.org/abs/2401.05749?ref=jina-ai-gmbh.ghost.io">Thompson, et al., 2024</a>, possibly half of the text on the Internet may be translated from another language, and a very large share of those translations are of poor quality and show signs of machine generation. This can distort a language model trained from such data.</p><p>As an example, below is a screenshot of <a href="https://ww1.habsburger.net/en/chapters/hamster-buying-queuing-do-it-yourself-individual-strategies-provide-food-become?ref=jina-ai-gmbh.ghost.io">a page from the website <em>Die Welt der Habsburger</em></a> showing clear evidence of machine translation. &#x201C;Hamster buying&#x201D; is an over-literal translation of the German word <em>hamstern</em>, meaning <em>to hoard</em>, or <em>panic-buying</em>. Too many instances of this will lead an AI model to think &#x201C;hamster buying&#x201D; is a real thing in English and that the German <em>hamstern</em> has something to do with pet hamsters.</p><figure class="kg-card kg-image-card"><img src="https://jina-ai-gmbh.ghost.io/content/images/2024/05/Screenshot-2024-05-03-at-15.07.20.png" class="kg-image" alt="When AI Makes AI: Synthetic Data, Model Distillation, And Model Collapse" loading="lazy" width="1532" height="1074" srcset="https://jina-ai-gmbh.ghost.io/content/images/size/w600/2024/05/Screenshot-2024-05-03-at-15.07.20.png 600w, https://jina-ai-gmbh.ghost.io/content/images/size/w1000/2024/05/Screenshot-2024-05-03-at-15.07.20.png 1000w, https://jina-ai-gmbh.ghost.io/content/images/2024/05/Screenshot-2024-05-03-at-15.07.20.png 1532w" sizes="(min-width: 720px) 720px"></figure><p>In almost every case, having more AI output in your training data is bad.

One of the biggest is to combat bias.</p><p>Large language models and image generators have received a lot of <a href="https://www.washingtonpost.com/technology/interactive/2023/ai-generated-images-bias-racism-sexism-stereotypes/?ref=jina-ai-gmbh.ghost.io">high-profile</a> <a href="https://www.washington.edu/news/2023/11/29/ai-image-generator-stable-diffusion-perpetuates-racial-and-gendered-stereotypes-bias/?ref=jina-ai-gmbh.ghost.io">complaints</a> <a href="https://www.theverge.com/2024/2/21/24079371/google-ai-gemini-generative-inaccurate-historical?ref=jina-ai-gmbh.ghost.io">about bias</a>. The word <em>bias</em> has a strict meaning in statistics, but these complaints often reflect moral, social, and political considerations that have no simple mathematical form or engineering solution.</p><p>The bias you don&#x2019;t easily see is far more damaging and much harder to fix. The patterns AI models learn to replicate are the ones seen in their training data, and where that data has systematic shortcomings, bias is an inevitable consequence. The more different things we expect AI to do &#x2014; the more diverse the inputs to the model &#x2014; the more chance there is for it to get something wrong because it never saw enough similar cases in its training.</p><p>The main role of synthetic data in AI training today is to ensure enough examples of certain kinds of situations are present in the training data, situations that may not be present enough in available natural data.</p><p>Below is an image that MidJourney produced when prompted with &#x201C;doctor&#x201D;: four men, three white, three in white coats with stethoscopes, and one genuinely old.

Below are the first three images found for &#x201C;doctor&#x201D; on the Shutterstock photo website: Three men, two older and white. AI&#x2019;s biases are the biases of its training, and if you train models using uncurated data, you will always find these kinds of biases.</p><figure class="kg-card kg-image-card"><img src="https://jina-ai-gmbh.ghost.io/content/images/2024/05/Screenshot-2024-05-03-at-15.21.21.png" class="kg-image" alt="When AI Makes AI: Synthetic Data, Model Distillation, And Model Collapse" loading="lazy" width="1740" height="860" srcset="https://jina-ai-gmbh.ghost.io/content/images/size/w600/2024/05/Screenshot-2024-05-03-at-15.21.21.png 600w, https://jina-ai-gmbh.ghost.io/content/images/size/w1000/2024/05/Screenshot-2024-05-03-at-15.21.21.png 1000w, https://jina-ai-gmbh.ghost.io/content/images/size/w1600/2024/05/Screenshot-2024-05-03-at-15.21.21.png 1600w, https://jina-ai-gmbh.ghost.io/content/images/2024/05/Screenshot-2024-05-03-at-15.21.21.png 1740w" sizes="(min-width: 720px) 720px"></figure><p>One way to mitigate this problem is to use an AI image generator to create images of younger doctors, women doctors, doctors who are people of color, and doctors wearing scrubs, suits, or other clothing, and then include them in training. Synthetic data used in this way can improve AI model performance, at least relative to some external norm, instead of leading to model collapse. However, artificially distorting training data distributions can create unintended side effects, <a href="https://www.theverge.com/2024/2/21/24079371/google-ai-gemini-generative-inaccurate-historical?ref=jina-ai-gmbh.ghost.io">as Google recently found out</a>.</p><h2 id="model-distillation">Model Distillation</h2><p><a href="https://jina.ai/news/distilled-ai-using-large-models-to-teach-smaller-ones/?ref=jina-ai-gmbh.ghost.io">Model distillation</a> is a technique for training one model directly from another one.

At first glance, it makes little sense to train a model that way, but there are benefits. The principal one is that the &#x201C;student&#x201D; model may be much smaller, faster, or more efficient than the &#x201C;teacher&#x201D;, while still closely approximating its performance.</p><p>The relationship between model size, training data, and final performance is complicated.

<p>Model distillation is a way to take a large model, one that costs too much to run, and use it to create a smaller, cheaper model. In every case, there is some performance loss, but in the best cases, it can be very small.</p><p>Given the costs associated with very large AI models, these benefits are quite substantial. Distillation makes models that run faster, on cheaper chips, with less memory, consuming less power.</p><p>Furthermore, large models can learn remarkably subtle patterns from uncurated data, patterns that a smaller model could never learn from the same data. A large model can then produce far more diverse training data than what it was trained with, enough that the smaller model may be able to learn the same subtle patterns. Once you have a large trained model, you can use it to &#x201C;teach&#x201D; what it&#x2019;s learned to a smaller model that could never have learned it alone. Distillation is, in those cases, sometimes a better way to learn than using real training data.</p><h2 id="so-are-we-all-going-to-hell-in-a-handbasket">So Are We All Going to Hell in a Handbasket?</h2><p>Maybe.</p><p>The good news is that without a solution to model collapse, we probably won&#x2019;t be able to train a superintelligent AI able to kill off humanity, at least not with the methods we&#x2019;ve been using.

The motto of machine learning has long been &#x201C;<a href="https://towardsdatascience.com/ai-ml-practicalities-the-unreasonable-effectiveness-of-data-c0bfd44c5057?ref=jina-ai-gmbh.ghost.io">more data is better data</a>.&#x201D; (Sometimes: &#x201C;There is no data like more data.&#x201D;) <a href="https://towardsdatascience.com/ai-ml-practicalities-more-data-isnt-always-better-ae1dac9ad28f?ref=jina-ai-gmbh.ghost.io">Statisticians all know this wrong</a>. Common sense says this is wrong. But it&#x2019;s a strategy that&apos;s been working for AI researchers for a long time, at least since I started as a researcher in machine translation in the early 2000s.</p><p>There are reasons for this. <em>Diverse data</em> &#x2014; data that includes many different possibilities &#x2014; is a much better training source than uniform data. And, in practice, in the real world, more data usually means more diverse data.</p><p>But we&#x2019;re running out of new sources of good, diverse data, and the creation of new human-made works is unlikely to keep up with AI generation. One way or another, we will eventually have to change how we do AI model training. Otherwise, we may reach a performance threshold that we can&#x2019;t beat anymore. This would transform the industry since the focus would shift from building and running larger, more expensive models to developing frameworks, contexts, and niches in which existing models can bring new added value.</p><h2 id="how-jina-ai-trains-its-ai-models">How Jina AI Trains its AI Models</h2><p>At Jina AI, we try to bring our users the benefits of AI best practices. Although we don&#x2019;t produce text-generating LLMs or AI image generators, we&#x2019;re still concerned with the problem of model collapse. We use subsets of the <a href="https://commoncrawl.org/?ref=jina-ai-gmbh.ghost.io">Common Crawl</a> for the bulk of our pre-training and then use curated and synthetic data to optimize the performance of our models. We strive to bring state-of-the-art performance to cost-effective models and compact, low-dimensional embeddings.</p><p>Nonetheless, model collapse is an inevitable problem for Common Crawl data. We expect to transition over time to using more curated data and less of the Common Crawl. We expect that other AI industry players will do the same. This will have costs &#x2014; both in terms of money and rate of quality improvement &#x2014; but it&#x2019;s too early to try to estimate them.</p><p>We use synthetic data in areas where embedding models have known problems. For example, AI models struggle to represent negation. &#x201C;Recipes with meat&#x201D; and &#x201C;recipes without meat&#x201D; typically have embeddings that are very close together, but users often need them to be very far apart. Our biggest use of synthetic data is creating a large corpus of AI-generated sentence pairs distinguished by that kind of negation (called <em>polarity</em> in AI and some kinds of linguistics), and then using it to improve our models.</p><p>For example, below is a 2D projection of hypothetical embeddings. &#x201C;Recipes with meat&#x201D; and &#x201C;Recipes without meat&#x201D; are relatively close together. &#x201C;Bacon Cheeseburger&#x201D; is much closer to &#x201C;Recipes with meat&#x201D; than to anything else, and &#x201C;Falafel&#x201D; is closer to &#x201C;Recipes without meat&#x201D; than to &#x201C;Recipes with meat.&#x201D; However, &#x201C;Bacon Cheeseburger&#x201D; is much closer to &#x201C;Recipes without meat&#x201D; than &#x201C;Falafel&#x201D; is.</p><figure class="kg-card kg-image-card kg-card-hascaption"><img src="https://jina-ai-gmbh.ghost.io/content/images/2024/05/Untitled--61-.png" class="kg-image" alt="When AI Makes AI: Synthetic Data, Model Distillation, And Model Collapse" loading="lazy" width="649" height="579" srcset="https://jina-ai-gmbh.ghost.io/content/images/size/w600/2024/05/Untitled--61-.png 600w, https://jina-ai-gmbh.ghost.io/content/images/2024/05/Untitled--61-.png 649w"><figcaption><span style="white-space: pre-wrap;">A 2D projection of hypothetical embeddings.</span></figcaption></figure><p>Looking solely at the embeddings, we might conclude that bacon cheeseburgers are a better example of a recipe without meat than falafel.</p><p>To prevent this, we train our models with synthetic data. We use an LLM to generate pairs of sentences with opposite polarities &#x2013; like &#x201C;X with Y&#x201D; / &#x201D;X without Y&#x201D; &#x2013; and train our embedding models to move those pairs apart. We also use synthetic data for other kinds of focused <a href="https://finetuner.jina.ai/advanced-topics/negative-mining/?ref=jina-ai-gmbh.ghost.io">negative mining</a>, a collection of techniques used to improve specific aspects of AI model performance by presenting it with curated data.</p><figure class="kg-card kg-image-card kg-card-hascaption"><img src="https://jina-ai-gmbh.ghost.io/content/images/2024/05/Untitled--62-.png" class="kg-image" alt="When AI Makes AI: Synthetic Data, Model Distillation, And Model Collapse" loading="lazy" width="649" height="579" srcset="https://jina-ai-gmbh.ghost.io/content/images/size/w600/2024/05/Untitled--62-.png 600w, https://jina-ai-gmbh.ghost.io/content/images/2024/05/Untitled--62-.png 649w"><figcaption><span style="white-space: pre-wrap;">A 2D projection of hypothetical embeddings after improving the underlying model with polarity-inverted sentence pairs.</span></figcaption></figure><p>We also use generative AI to train <a href="https://jina.ai/news/elevate-your-code-search-with-new-jina-code-embeddings/?ref=jina-ai-gmbh.ghost.io">embedding models for programming languages</a>, taking advantage of large models that generate copious code examples, so that we can correctly embed even fairly obscure features of specific languages and frameworks.</p><p>Model distillation is key to how we produce <a href="https://jina.ai/news/smaller-faster-cheaper-jina-rerankers-turbo-and-tiny?ref=jina-ai-gmbh.ghost.io">compact models that save computer resources</a>. Distillation is a lot more efficient and reliable than training from scratch, and our results show that a distilled model can still have top-quality performance. The table below shows Jina AI&#x2019;s distilled <a href="https://jina.ai/reranker?ref=jina-ai-gmbh.ghost.io">reranker models</a> compared to the base reranker used to train them and to other models with far more parameters but poorer performance.</p>

URL Source: https://www.theregister.com/2024/04/19/tesla_recalls_all_3878_cybertrucks/?td=rt-3a

Published Time: 2024-04-19T13:55:08Z

Markdown Content:
Tesla has issued a recall notice for every single Cybertruck it has produced thus far, a sum of 3,878 vehicles.

Today&apos;s [recall notice](https://static.nhtsa.gov/odi/rcl/2024/RCLRPT-24V276-7026.PDF) \[PDF\] by the National Highway Traffic Safety Administration states that Cybertrucks have a defect on the accelerator pedal, which can get wedged against the interior of the car, keeping it pushed down. The pedal actually comes in two parts: the pedal itself and then a longer piece on top of it. That top piece can become partially detached and then slide off against the interior trim, making it impossible for the pedal to lift up. This defect [was already suspected](https://www.theregister.com/2024/04/15/tesla_lays_off_10_percent/) as Tesla paused production of the Cybertruck due to an &quot;unexpected delay.&quot; Some Cybertruck owners also spoke on social media about their vehicles uncontrollably accelerating, with one crashing into a pole and another demonstrating [on film](https://www.tiktok.com/@el.chepito1985/video/7357758176504089898) how exactly the pedal breaks and gets stuck.

It&#x2019;s a reliable and time-tested technology. Switching to a completely new system isn&apos;t just a major step, it often proves to be impractical, demanding substantial resources and a thorough overhaul of operations. Additionally, BM25 is a cornerstone of lexical search engines, commonly employed in widespread search engine platforms like Elasticsearch and Solr. It already delivers strong results for many use cases.</p><p>Many companies therefore hesitate to completely transition to neural search, despite convincing evidence that AI-based search <a href="https://db-engines.com/en/ranking_trend?ref=jina-ai-gmbh.ghost.io" rel="noreferrer">significantly improves user satisfaction and result quality</a>.</p><h2 id="retrieval-agnostic-neural-reranking">Retrieval-Agnostic Neural Reranking</h2><p>Reranker is a groundbreaking addition to the search system landscape. Designed to enhance the value of existing search engines such as <a href="https://www.elastic.co/elasticsearch?ref=jina-ai-gmbh.ghost.io">Elasticsearch</a>, it serves as an extra layer, working like an add-on to refine the delivered search quality. It doesn&apos;t need to know what kind of search technology it&apos;s connected to, it just takes a list of matches and reorders them to be better.</p><p>Jina Reranker adds a deeper level of understanding to traditional search technologies. Algorithms like BM25 do a good job of retrieving documents based on term frequency but struggle to evaluate the meaning of the texts they retrieve in light of the user&apos;s intent. This is where AI excels: Reranker helps produce outcomes that are better aligned with what users are looking for.</p><p>Therefore, for businesses that want to bring the powerful advantages of AI models to their search frameworks, adding Jina Reranker can be a wise decision and doesn&apos;t incur the burdens of replacing an existing search infrastructure. It&#x2019;s about refining search results to make them not just acceptable, but exceptional: more relevant and more accurate.</p><h2 id="why-jina-reranker">Why Jina Reranker?</h2><p>Among reranker models, <a href="https://jina.ai/reranker?ref=jina-ai-gmbh.ghost.io">Jina Reranker models</a> stand out as <a href="https://jina.ai/news/maximizing-search-relevancy-and-rag-accuracy-with-jina-reranker/?ref=jina-ai-gmbh.ghost.io">frontrunners</a> with state-of-the-art scores on <a href="https://jina.ai/news/smaller-faster-cheaper-jina-rerankers-turbo-and-tiny?ref=jina-ai-gmbh.ghost.io">performance benchmarks</a>.</p><figure class="kg-card kg-bookmark-card"><a class="kg-bookmark-container" href="https://jina.ai/news/maximizing-search-relevancy-and-rag-accuracy-with-jina-reranker/?ref=jina-ai-gmbh.ghost.io"><div class="kg-bookmark-content"><div class="kg-bookmark-title">Maximizing Search Relevance and RAG Accuracy with Jina Reranker</div><div class="kg-bookmark-description">Boost your search and RAG accuracy with Jina Reranker.

This architecture enables support for long text sequences, with our models accepting up to 8,192 tokens, ideal for deep analysis of larger documents and complex queries requiring detailed language understanding.</p><p>The Turbo and Tiny models draw on insights gained from <a href="https://jina.ai/news/maximizing-search-relevancy-and-rag-accuracy-with-jina-reranker/?ref=jina-ai-gmbh.ghost.io">Jina Reranker v1</a>. Reranking can be a major bottleneck for information retrieval applications. Traditional search applications are a very mature technology whose performance is well-understood. Rerankers add a great deal of precision to text-based retrieval, but AI models are large and can be slow and expensive to run.</p><p>Many users would prefer a smaller, faster, cheaper model, even if it comes at some cost to accuracy. Having a single goal &#x2013; reranking search results &#x2013; makes it possible to streamline the model and bring users competitive performance in much more compact models. <strong>By using fewer hidden layers, we speed up processing and reduce model size. </strong>These models cost less to run, and the greater speed makes them more useful for applications that can&apos;t tolerate much latency, while retaining nearly all of the performance of larger models.</p><p>In this article, we&apos;ll show you the architecture of Reranker Turbo and Reranker Tiny, measure its performance, and show you how to get started with them.</p><h2 id="streamlined-architecture">Streamlined Architecture</h2><p>Jine Reranker Turbo (<code>jina-reranker-v1-turbo-en</code>) uses a <strong>six-layer architecture, with a total of 37.8 million parameters</strong>, in contrast to the 137 million parameters and twelve layers of the base reranker model <code>jina-reranker-v1-base-en</code>. This represents a reduction in model size of three-quarters and as much as a tripling of processing speed.</p><p>Reranker Tiny (<code>jina-reranker-v1-tiny-en</code>) uses <strong>four layers with 33 million parameters</strong>, providing even greater parallel processing and faster speeds &#x2013; almost five times as fast as the base Reranker model &#x2013; while saving 13% of memory costs over the Turbo model.</p><figure class="kg-card kg-image-card kg-card-hascaption"><img src="https://jina-ai-gmbh.ghost.io/content/images/2024/04/barchart_1.png" class="kg-image" alt="Smaller, Faster, Cheaper: Introducing Jina Rerankers Turbo and Tiny" loading="lazy" width="1102" height="675" srcset="https://jina-ai-gmbh.ghost.io/content/images/size/w600/2024/04/barchart_1.png 600w, https://jina-ai-gmbh.ghost.io/content/images/size/w1000/2024/04/barchart_1.png 1000w, https://jina-ai-gmbh.ghost.io/content/images/2024/04/barchart_1.png 1102w" sizes="(min-width: 720px) 720px"><figcaption><span style="white-space: pre-wrap;">Document throughput for Jina Reranker models</span></figcaption></figure><h2 id="knowledge-distillation">Knowledge Distillation</h2><p>We&apos;ve trained Reranker Turbo and Tiny using <a href="https://jina.ai/news/distilled-ai-using-large-models-to-teach-smaller-ones/?ref=jina-ai-gmbh.ghost.io">knowledge distillation</a>. This is a technique for using an existing AI model to train another one to match its behavior. Instead of using external data sources, we use an existing model to generate data for training. We used the Jina Reranker base model to rank collections of documents and then used those results to train both Turbo and Tiny. This way, we can bring much more data into the training process because we aren&apos;t limited by available real-world data.</p><p>This is a bit like a student learning from a teacher: The already trained, high-performance model &#x2013; the Jina Reranker Base model &#x2013; &quot;teaches&quot; the untrained Jina Turbo and Jina Tiny models by generating new training data. This technique is widely used to create small models from large ones. At its best, the difference in task performance between the &quot;teacher&quot; model and the &quot;student&quot; can be very small.</p><h2 id="evaluation-on-beir">Evaluation on BEIR</h2><p>The benefits of streamlining and knowledge distillation come at relatively little cost to performance quality. On the <a href="https://github.com/beir-cellar/beir?ref=jina-ai-gmbh.ghost.io">BEIR benchmark</a> for information retrieval, <code>jina-reranker-v1-turbo-en</code> scores just under 95% of the accuracy of <code>jina-reranker-v1-base-en</code>, and <code>jina-reranker-v1-tiny-en</code> scores 92.5% of the base model&apos;s score.</p><p>All Jina Reranker models are competitive with other popular reranker models, most of which have much larger sizes.</p>
