AI Appraisal and Hype

Articles and resources that appraise versus hype machine learning, deep learning, and artificial intelligence

Throughout my career, I have found "artificial intelligence" to be an interesting buzzword. Of course, almost every buzzword that enters corporate jargon (e.g. "Big Data", "Internet of Things", "Blockchain", "BitCoin", etc) is often hyped beyond actual value. But "artificial intelligence" is different because unlike other buzzwords, "AI" has already gone through cycles of AI booms and "AI Winters" over several decades.

While many of my colleagues in operations research circles dismiss the "artificial intelligence" buzzword as media hype and tabloid, such hype has still had an effect on society. Many Fortune 500 executives, law makers, venture capitalists, the general population, and even technology professionals are under the impression Skynet is upon us. Billions of U.S. dollars are poured into AI research, but most people funding such initiatives do not quite understand the technology or what it actually is good at. Anecdotally, I have also noticed programmers, data scientists, and other technology professionals become invested in AI but rarely scrutinize its capabilities and limits.

My Pocket bookmarks are getting full with these articles, so I am going to start dumping them here on this GitHub page for my own organization and to share with others. Feel free to contribute your own too. It is fascinating to compare these two narratives and how they contrast each other, and it will be interesting to see how things play out as investors and CEO's start demanding financial return from AI technologies.

Summarizing the Narratives

Based on the articles and resources listed below, here are the bullet points that objectively summarize proponent and critical perspectives on contemporary "AI" trends tied to machine learning:

Proponent Points

  • Useful applications have been developed with machine learning, particularly image recognition, natural language processing, and image/audio generation.

  • Machine learning has unlocked new ways to perform more powerful regressions that were impossible to do before, like fitting a regression to the pixels on an image.

  • Having more data and computing power (e.g. quantum computing) will create more applications in the future.

Critical Points

  • Machine learning requires large amounts of labeled data that may not be practical to obtain in real-world applications. This is one reason why AI research is fond of applying machine learning to games like Chess, Go, Super Mario, and StarCraft. With these games, it is easy to generate enormous amounts of data from virtual players playing against themselves. However, this is not something that can be done in most real-world applications.

  • Heuristics and other algorithms that leverage business domain knowledge will outperform machine learning approaches in most cases, in terms of cost and resources as well as effectiveness. While heuristics do not guarantee a perfect solution, they are far less data-hungry than machine learning and can be far more effective.

  • Machine learning is primarily only good at two things: regression and categorization. It quickly has a diminishing return in other spaces like the Traveling Salesman Problem. The most interesting problems in the real world are not regression and categorization, but rather require a broader system of intuition, human experience, domain knowledge, and unquantifiable ideas.

  • Machine learning (and algorithms in general) need a single task with a single objective to be practically useful, and trying to generalize multiple unrelated objectives and tasks will quickly have a diminishing return (No Free Lunch Theorem). This is another reason why AI research gravitates towards board games and video games, as there is a single quantifiable objective and a confined world structure, with only a fixed number of moves, inputs, and outputs.

  • Machine learning (and nondeterministic algorithms in general), need manual tuning and human experimentation with many hyperparameters before they can behave "intelligently" when applied to a tightly scoped problem.

  • The nature and definition of "intelligence" and "consciousness" is currently philosophical, meaning we have little to no idea how we understand this human phenomena much less replicate it on a machine. The pursuit of "general artificial intelligence" is guided by speculations and philosophy, and even leads AI researchers to wonder if their iPhone has feelings. Philosophy has a way of eluding practical matters and creating unproductive rabbit holes. If you are following Elon Musk, a high-profile investor towards AI research, one moment the conversation can be how to strategically leverage AI in a business, and the next it regresses into funding research to break out of the Matrix or summoning the AI demon.
