A saturated model is one that +exactly predicts the data (which can always be accomplished by a model that +has one parameter per data point). Hence it represents the situation with the +maximum possible log-likelihood when predicting this particular set of data. +Deviance is closely related to a simpler calculation (-2 × log likelihood) that +forms the basis of a couple of well-known metrics for model comparison (the +Akaike information criterion, AIC, and the Bayesian information criterion, +BIC) and indeed is occasionally defined this way. That's because we are of- +ten only really interested in differences (in Deviance, or AIC, or BIC) between +models, and the log-likelihood of the saturated model gets subtracted out in a +comparison between two models (because it has contributed to the deviance +in the same way for both) SO calculating it is not necessary. + +However, if you want to say something about the goodness of fit of a model +without relating it to any other model, based on asymptotic statistical theory, +you do need to calculate deviance properly.

Rather +than looking at the things of the Nights as colorful +details in Sheherazade's tales or protagonists in the +fantastic stories they make for themselves, we could +explore, instead, their role as as bearers of cultural +knowledge unintentionally embedded in the fabric +of the text. In such a reading, "historically and theo- +retically overdetermined material charactersitics +of objects are sought out beyond the immediate +context in which they appear"86 in order to + +defetishize them and expose the power structures +in which they are involved. + +Thus, as Makdisi and Nussbaum sum up in their +introduction to The Arabian Nights in Historical +Context: Between East and West, "the Nights offered +a particularly powerful vision of an Asiatic culture +seemingly saturated with references to sensuality, +extravagance, indulgence, violence, supernatural- +ism, and eroticism ... [and] added a supernatural +dimension to the Enlightenment; the tales offered +an avenue into modernity through its magical op- +posite, an alternative to European identity, and an +antidote to neoclassicism."87 However, reading +such imports as an expression of European pow- +ers' disavowal of the East in order to "justify their +conquest and rule over other peoples, particularly +in Asia,"88 is an oversimplification of a rather com- +plicated process of cultural exchange. None of +these descriptions of Arabia were caused by colo- +nial "distortions," as Said feared, but by false attri- +butions: "Arabian" was a misnomer that rarely de- +scribed Arabia itself. While fictional narratives like +Arabian Nights' Entertainments represented Ara- +bia as a land of magic and exorbitant riches, they +were too far-fetched to be part of a Westerner's +belief system during the Age of Reason; rather, +they were popularized because their wild fiction- +ality turned them into bestsellers at the time. Such +stories competed with descriptions of the Arabi- +an Peninsula by travelers and traders who had vis- +ited the area and had unmediated contact with the +local culture. However, while the Orientalist litera- +ture described Arabia in terms that emphasized +its exoticism, magic, superstitions, extravagance, +wealth, eroticism, excess, and myriads of other pe- +culiarities that contrasted it with the European +normativity, travel narratives created an "Arabian" +identity that was generally congruent with the +reality of the place. + +86 Elaine Freedgood, "Introduction: Reading Things," in +The Idea in Things: Fugitive Meaning in the Victorian +Novel (Chicago: University of Chicago Press, 2006), +5-6. + +87 Makdisi and Nussbaum, introduction to The Arabian +Nights in Historical Context, 5. +88 Ibid. \ No newline at end of file diff --git a/benchmark/ground-truth/markdown-2026-03-25/01030000000012.md b/benchmark/ground-truth/markdown-2026-03-25/01030000000012.md new file mode 100644 index 0000000..4c7f2c6 --- /dev/null +++ b/benchmark/ground-truth/markdown-2026-03-25/01030000000012.md @@ -0,0 +1,55 @@ +96 + +MACDONALD + +FIGURE 5.1 Mr. Bologna Jun-r as Kalim Azack in Aladdin, or +The Wonderful Lamp. + +theatrical prints, which are informed by intercul- +turation and illustrate the Orientalized look of the +tale's theatrical life: one of John ("Jack") Peter Bo- +logna as Kalim Azack, the vizier's son betrothed to +Badroulboudour, and one of the extraordinary +pantomime clown Joseph Grimaldi as Kazrac, the +magician's Chinese slave, who, disillusioned by the +magician's cruel plans concerning the lamp, be- +friends Aladdin (figs. 5.1 and 5.2).

But my conclusion here is that we must actually accept Boltzmann's +argument in both directions of time and hence we are led to the following: + +Principle 1. At every moment of time t and for every state with entropy S, there +are very many "accessible states" with higher entropy, both at the previous moment +of time t - 1 and at the next one t + 1. On the other hand, the chance for finding +such accessible states with lower entropy, both at times t - 1 and t + 1, is extremely +small. + +This principle also implies a shift of perspective in the search for time's arrow. +Rather than trying to find the reason for the asymmetry, we must concentrate on +understanding why we cannot observe the symmetric structure of the multiverse as +a whole. + +As still one more simplification, let us assume that the entropy can only change +by ±1 during each unit of time. This assumption, however, has to be modified near +the endpoints (BB and BC) for the following reason: it is a very important aspect of +this approach to assume that physics during the first and last moments is very +different from the rest of the time, since at these moments quantum phenomena +can be expected to become global. To model this in a simple way, we can split the +life-span of our multiverse up into three parts: + +{\left[-T_0,-T_1\right]\cup\left[-T_1,T_1\right]\cup\left[T_1,T_0\right]\text{.}} + +(4) + +Here the first and last parts may be called "the extreme phases," which are +characterized by the property that transition between very different states can be +possible.

Decades later, the suffragist movement ushered in one of the first +national issues to have brought Filipino women together. It was a hard- +fought battle; the movement had to contend with staunch opposition +from antisuffragists in the Constitutional Convention that drafted the +1935 Constitution. The reluctance was expected because only 21-year- +old Filipino men had been allowed to vote during the time. They framed +their opposition based on traditional notions of womanhood and their +role in the private sphere, foremost of which is motherhood. Another +key argument against female suffrage was the idea that politics is +supposed to be "dirty" and that this would taint families if women took +part in politics. The assumptions catered to the age-old public-private +divide, strongly suggesting that only men are qualified to occupy the +former. + +Eventually, the 1935 Constitution granted women suffrage on the +condition that more than 300,000 women would vote affirmatively in a +plebiscite. When signing the law paving the way for the said plebiscite, +President Manuel Quezon had this to say to Filipino men: "Are you +going to deprive our women of the opportunity to say how their lives +are going to be regulated and is it fair for us to presume that men can +always speak in this country for women?" (Official Gazette 1936). In +April 1937, more than 400,000 women voted in favor of their right to +vote and participate in political life. In 1946 and 1947, Filipinos elected +the first woman member of the House of Representatives, and senator, +respectively. Nonetheless, data from 1946 to 1992 indicate an uphill +climb. For instance, in the 1949 and 1953 elections for the House of +Representatives, only one woman was elected out of the 100 positions. \ No newline at end of file diff --git a/benchmark/ground-truth/markdown-2026-03-25/01030000000049.md b/benchmark/ground-truth/markdown-2026-03-25/01030000000049.md new file mode 100644 index 0000000..661e0da --- /dev/null +++ b/benchmark/ground-truth/markdown-2026-03-25/01030000000049.md @@ -0,0 +1,42 @@ +Overcoming Barriers to Filipino Women's Political Representation 9 + +The post-World War II period saw women participating in formal +politics and even attempting to form a political party and an alliance +supporting President Ramon Magsaysay's candidacy for the presidency +(He served as president from 1953 to 1957), while the advent of the +martial law period in 1972 witnessed feminist movements.

Studying and practicing behavioral economics should occur +simultaneously, which, in turn, suggests a course taught more according to a practicum approach than +in a traditionally styled lecture format. As such, the book's information and lessons are presented in a +succinct and precise format. + +The goal of this textbook is to help students experience behavioral economics through actual +participation in the same experiments and economic games that have served as the foundations for, +and shaped the contours of, the field. With the help of this book, students have the opportunity to +learn behavioral economics firsthand and, in the process, create their own data and experiences. They +will learn about themselves-about how they make private and public choices under experimental +conditions-at the same time as they learn about the field of behavioral economics itself. They will be +both the subjects and students of behavioral economics. What better way to learn? + +# HOMO ECONOMICUS VS. HOMO SAPIENS + +For ease of reference and exposition, we henceforth refer to the type of individual construed by the +traditional rational-choice model as Homo economicus, a peculiar subspecies of human beings that is +unfailingly omniscient, dispassionate, and self-interested when it comes to making choices. Homo +sapiens, on the other hand, represents the rest of us-the often-flawed reasoners and sometimes- +altruistic competitors who are prone to making decisions based primarily on emotion and +heuristics.1,2 + +# THE TEXTBOOK'S DIFFERENT SECTIONS + +The textbook consists of four sections that, taken together, portray in full the eclectic methodologies +comprising the field of behavioral economics.

As an example of this phenomenon, Bauer et al. (2012) asked participants in an online survey to imagine +themselves as one of four households facing a water shortage due to a drought affecting their shared well.

The thought experiments in Section 1 are, for the +most part, re-castings of the simple cognitive tests devised by psychologists and economists over the +past three-to-four decades to illustrate the fallacies, miscalculations, and biases distinguishing Homo +sapiens from Homo economicus. Similarly, the laboratory experiments presented in Section 2 are, for the +most part, re-castings of the seminal experiments conducted by Kahneman and Tversky (among many +others). These experiments helped motivate the revised theories of human choice behavior, such as +Kahneman and Tversky's (1979) Prospect Theory, which form another pillar of behavioral economics. +Alongside these experiments, Section 2 presents the revised theories of human choice behavior with +varying degrees of rigor. This is where the theoretical bases of Homo economicus' rational choice +behavior are examined, and where key refinements to this theory are developed-theoretical +refinements underpinning the myriad departures from rational choice behavior we witness Homo +sapiens make in this section's laboratory and field experiments (and which are examined further in +Sections 3 and 4). + +Section 3 submerses the student in the world of behavioral game theory. Here we explore games +such as Ultimatum Bargaining presented in Example 5. We follow Camerer (2003)'s lead, first by +characterizing the games analytically (i.e., identifying solution, or equilibrium, concepts that are +predicted to result when members of Homo economicus play the games), and then by discussing +empirical results obtained from corresponding field experiments conducted with Homo sapiens. It +is within the context of these games and field experiments that theories of social interaction are +tested concerning inter alia trust and trustworthiness, honesty, fairness, reciprocity, etc. As with the +thought and laboratory experiments presented in Sections 1 and 2, the games and field experiments +presented in Section 3 are meant to be replicated with students as subjects and the instructor as the +experimenter, or researcher. + +Finally, Section 4 wades into the vast sea of empirical research and choice architecture. Here the +student explores studies reporting on (1) the outcomes of actual policy nudges, such as the SMarT +retirement-savings plan presented in Example 3 of the Introduction, (2) analyses of secondary datasets +to test for choice behavior consistent with the revised theories discussed in Section 2, such as the test +for loss aversion in Example 4 of the Introduction, and (3) analyses of primary datasets obtained from +novel field experiments to further test the revised theories. The main purpose of this section is not +only to introduce the student to interesting empirical studies and policy adaptations in the field of +behavioral economics, but also, in the process, to incubate in the student an abiding appreciation for +the obscure settings that sometimes lend themselves to such study.3 + +# THE TEXTBOOK'S DIFFERENT LEVELS OF RIGOR + +Because the mathematical and computational rigor of material presented in this textbook varies +throughout, particularly in Sections 2 - 4, the extent of the rigor used in the presentation of a +given topic is indicated with superscripts.

On August 1st, 2015, the city began providing a +"green nudge" to citizens living in its urban core area with the introduction of the Clear Bag Policy, a +policy designed to nudge households toward more responsible sorting of their waste, which, in turn, +would result in an overall reduction in the total amount of waste generated. As Akbulut-Yuksel and +Boulatoff point out, under the new policy, households were mandated to replace their black garbage +bags, traditionally used for the disposal of their refuse, with clear, transparent bags. The Clear Bag +Policy allowed households to put out the same number of garbage bags at the curb (six every other +week), but all waste destined for the landfill was required to be disposed of in a clear bag (except for +one dark bag permitted for privacy's sake). This allowed waste collectors to screen and refuse any bags +containing materials that should otherwise have been diverted from the landfill, such as recyclables, +food waste, and hazardous waste. Clear bags also made apparent to everyone, neighbors and passersby +alike, a given household's waste-generation and disposal habits.33 + +To test the Clear Bag Policy's impact on a typical household's generation of MSW, Akbulut-Yuksel +and Boulatoff designed a quasi-experiment spanning the period from January 6, 2014, to July 28, +2017, with January 6, 2014, to July 31, 2015, serving as the pre-treatment period and August 1, 2015, +to July 28, 2017, serving as the post-treatment period. MSW data collected during this time span + +33. As Akbulut-Yuksel and Boulatoff point out, Halifax households are required to sort waste in four ways: (1) recyclable +containers (plastics, glass, and aluminum) are put in a transparent blue bag, (2) paper and cardboard are put in a separate +bag, (3) organic food waste goes in a green bin provided by the city, and (4) the remaining waste (refuse) goes into garbage +bags. Recyclable materials are collected each week, while garbage and organic waste are each collected every other week on +opposite weeks (except in the summer months when, thank goodness, organic waste is collected on a weekly basis). + +234 ARTHUR J.

Here I review the history +of trout fishing and fly-fishing with special focus on the Rocky Mountain West, where fly fishers first exerted +their influence on conservation ethics and sportfishing policy. Although many individuals and organizations +played roles, I concentrate on only two: Fly Fishers International (FFI) and Trout Unlimited (TU). These two +organizations had similar interests in conservation, but important differences prevented them from working +together on a unified goal of conservation. The legacy of fly-fishing demonstrates the importance of passion, +persistence, and partnerships in fish conservation. + +Trout and salmon are the only sport fish native to the Western states, and fly-fishing here became more than +a leisure activity. Norman Maclean's novel, A River Runs through It (1976), begins, "In our family there was no + +clear line between religion and fly fishing." Later Maclean writes that "Something within fishermen 1 tries to +make fishing into a world perfect and apart." The iconography of Western fly-fishing that Maclean and others +wrote about was created by anglers, fisheries managers, tourists, guides, businesses, and region promoters. The +history of Rocky Mountain fly-fishing parallels the history of the expansion of our Western frontier as well as +fisheries management (Brown 2015). Although Henry David Thoreau (1862) maintained that "In wildness is the +preservation of the world," humans are part of the trout fishing system and helped create, destroy, maintain, +and restore the trout fishing we have today. + +The first trout fishers were Native Americans. Native Americans used a variety of fishing methods, including +weirs, spears, nets, traps, baskets, hook-and-line methods, and baits. They also caught fish by hand via tickling. +Tickling for trout involves rubbing the underbelly of a trout with fingers to get the trout to go into a trance, after +which they can then easily be thrown onto the bank (Martindale 1901). Native Americans were more patient +than others. This method is different from noodling for catfish, where the noodler uses fingers as bait and grabs +the catfish by its mouth. Native Americans also caught fish by fly-fishing with deer-hair flies, according to the +writings of early American naturalist William Bartram (1739-1823) (Monahan, no date). + +The story of Rocky Mountain trout fishing begins with displacement of Native Americans from their historical +fishing and hunting grounds. Uninhabited wilderness had to be created through the dispossession of Native +people before it could be preserved (Spence 1999). Explorers, trappers, pioneers, soldiers, and homesteaders +brought fishing gear to frontier outposts. The Lewis and Clark Expedition (1804-1806) included a designated +angler named Silas Goodrich. The expedition first described several new species of fish, including the +Yellowstone Cutthroat Trout and Westslope Cutthroat Trout, caught by Goodrich. Later military expeditions +spent time trout fishing in addition to fighting Native Americans.

Long description. + +Creel limits are one of many elements that may be used by anglers to define fishing success. When more +fish are harvested per trip, anglers rate fishing higher. High creel limits may cause anglers to have unrealistic +expectations about the potential supply of fish compared to the demand (Cook et al. 2001). Creel limit +reductions may be unsuccessful in reducing angler harvest or affecting fish populations. The hypothetical +angler success graph (Figure 10.5) demonstrates that a reduction in creel from 8 to 4 would affect only a few +trips and result in a small harvest reduction. Furthermore, creel limits are applied on a per-angler basis, SO they +cannot control total harvest if total fishing effort increases or if noncompliance is high. Finally, since anglers +have a variety of motivations, they likely respond differently to regulation changes (Beard et al. 2011). + +The ethic of fairness is involved in setting creel limit regulations because many anglers do not harvest a single +fish during an angling trip. In Wisconsin lakes, Walleye harvest was not equally distributed. Only 7.4% of Walleye +angler trips were successful in harvesting at least one Walleye, and <1% harvested a limit during a fishing trip +(Staggs 1989). In Minnesota, anglers were slightly more successful, where 27.2% of angler trips ended with a +harvest of at least one Walleye and about 1% harvesting a limit. The ideal creel limit would distribute the catch +among more anglers and prevent overuse by a few individuals. + +Long-term trends in panfish populations (i.e., Bluegill, Yellow Perch, Black Crappie, Pumpkinseed, and Rock +Bass) in Wisconsin lakes showed significant declines due to overfishing (Rypel et al. 2016).

The Dutch police +optimized the procedures of speed control such that this effort has become very profitable to the +Dutch government. Various strategies for speed control are carried out by police forces, which +are all based on the position of the vehicle at consecutive times. The actual velocity follows from +the first-order derivative of the position of the vehicle with respect to time.

This motivates the use +of approximate derivatives, also called numerical derivatives. If the police want to know whether +the offender drove faster before speed detection (in other words, whether the perpetrator hit the +brakes after having seen the police patrol), or whether the driver was already accelerating, then +they are also interested in the acceleration of the 'bad guy'. This acceleration can be estimated +using numerical approximations of the second-order derivative of the car position with respect +to time. + +Since the time-interval of recording is nonzero, the velocity is not determined exactly in general. +In this chapter, the resulting error, referred to as the truncation error, is estimated using Taylor se- +ries.

In contrast to other LLM up-scaling +methods that use mixture-of-experts, DUS does +not require complex changes to train and infer- +ence efficiently.

SOLAR 10.7B is pub- +licly available under the Apache 2.0 license, +promoting broad access and application in the +LLM field 1. + +# 1 Introduction + +The field of natural language processing (NLP) +has been significantly transformed by the introduc- +tion of large language models (LLMs), which have +enhanced our understanding and interaction with +human language (Zhang et al., 2023a). These ad- +vancements bring challenges such as the increased +need to train ever larger models (Rae et al., 2021; +Wang et al., 2023; Pan et al., 2023; Lian, 2023; +Yao et al., 2023; Gesmundo and Maile, 2023) OW- +ing to the performance scaling law (Kaplan et al., +2020; Hernandez et al., 2021; Anil et al., 2023; +Kaddour et al., 2023). To efficiently tackle the +above, recent works in scaling language models +such as a mixture of experts (MoE) (Shazeer et al., +2017; Komatsuzaki et al., 2022) have been pro- +posed. While those approaches are able to effi- + +ciently and effectively scale-up LLMs, they often +require non-trivial changes to the training and infer- +ence framework (Gale et al., 2023), which hinders +widespread applicability. Effectively and efficiently +scaling up LLMs whilst also retaining the simplic- +ity for ease of use is an important problem (Alberts +et al., 2023; Fraiwan and Khasawneh, 2023; Sallam +et al., 2023; Bahrini et al., 2023). + +Inspired by Komatsuzaki et al. (2022), we +present depth up-scaling (DUS), an effective and +efficient method to up-scale LLMs whilst also re- +maining straightforward to use. DUS consists of +scaling the base model along the depth dimension +and continually pretraining the scaled model. Un- +like (Komatsuzaki et al., 2022), DUS does not scale +the model using MoE and rather use a depthwise +scaling method analogous to Tan and Le (2019) +which is adapted for the LLM architecture. Thus, +there are no additional modules or dynamism as +with MoE, making DUS immediately compatible +with easy-to-use LLM frameworks such as Hug- +gingFace (Wolf et al., 2019) with no changes to +the training or inference framework for maximal +efficiency.

We initialize the +Llama 2 architecture with pretrained weights from +Mistral 7B, as it is one of the top performers com- +patible with the Llama 2 architecture. By adopting +the Llama 2 architecture for our base model, we +aim to leverage the vast pool of community re- +sources while introducing novel modifications to +further enhance its capabilities. + +Depthwise scaling. From the base model with n +layers, we set the target layer count s for the scaled +model, which is largely dictated by the available +hardware. + +With the above, the depthwise scaling process +is as follows. The base model with n layers is +duplicated for subsequent modification. Then, we +remove the final m layers from the original model +and the initial m layers from its duplicate, thus +forming two distinct models with n - m layers. +These two models are concatenated to form a scaled +model with s = 2·(n-m) layers. Note that n = 32 +from our base model and we set s = 48 considering + +our hardware constraints and the efficiency of the +scaled model, i.e., fitting between 7 and 13 billion +parameters.

For the instruction +tuning process, we utilized the Alpaca-GPT4 (Peng et al., 2023), OpenOrca (Mukherjee et al., 2023), and Synth. +Math-Instruct datasets, while for the alignment tuning, we employed the Orca DPO Pairs (Intel, 2023), Ultrafeedback +Cleaned (Cui et al., 2023; Ivison et al., 2023), and Synth.

We +attribute the success of DUS to reducing such dis- +crepancies in both the depthwise scaling and the +continued pretraining steps. We also hypothesize +that other methods of depthwise scaling could also +work for DUS, as long as the discrepancy in the +scaled model is sufficiently contained before the +continued pretraining step. + +Comparison to other up-scaling methods. Un- +like Komatsuzaki et al. (2022), depthwise scaled +models do not require additional modules like gat- +ing networks or dynamic expert selection.

A DUS model can seam- +lessly integrate into existing training and inference +frameworks while maintaining high efficiency. + +# 3 Training Details + +After DUS, including continued pretraining, we +perform fine-tuning of SOLAR 10.7B in two stages: +1) instruction tuning and 2) alignment tuning. + +Instruction tuning. In the instruction tuning +stage, the model is trained to follow instructions in +a QA format (Zhang et al., 2023b). We mostly use +open-source datasets but also synthesize a math QA +dataset to enhance the model's mathematical capa- +bilities. A rundown of how we crafted the dataset is +as follows. First, seed math data are collected from +the Math (Hendrycks et al., 2021) dataset only, to +avoid contamination with commonly used bench- +mark datasets such as GSM8K (Cobbe et al., 2021). +Then, using a process similar to MetaMath (Yu +et al., 2023), we rephrase the questions and an- +swers of the seed math data. We use the resulting +rephrased question-answer pairs as a QA dataset + +and call it 'Synth. Math-Instruct'. + +Alignment tuning. In the alignment tuning stage, +the instruction-tuned model is further fine-tuned to +be more aligned with human or strong AI (e.g., +GPT4 (OpenAI, 2023)) preferences using direct +preference optimization (DPO) (Rafailov et al., +2023). Similar to the instruction tuning stage, we +use mostly open-source datasets but also synthe- +size a math-focused alignment dataset utilizing the +'Synth. Math-Instruct' dataset mentioned in the +instruction tuning stage. + +The alignment data synthesis process is as +follows. We take advantage of the fact that +the rephrased question-answer pairs in Synth. +Math-Instruct data are beneficial in enhancing the +model's mathematical capabilities (see Sec. 4.3.1). +Thus, we speculate that the rephrased answer to the +rephrased question is a better answer than the orig- +inal answer, possibly due to the interim rephrasing +step. Consequently, we set the rephrased question +as the prompt and use the rephrased answer as the +chosen response and the original answer as the re- +jected response and create the {prompt, chosen, +rejected} DPO tuple. We aggregate the tuples from +the rephrased question-answer pairs and call the +resulting dataset 'Synth. Math-Alignment'. + +# 4 Results + +# 4.1 Experimental Details + +Training datasets.

+ + +Table 7: Ablation studies on the different merge methods used for obtaining the final model. We use 'Cand. 1' +and 'Cand. 2' from Tab. 6 as our two models for merging. We name the merged models with the 'Merge' prefix to +indicate they are merged. The best scores for H6 and the individual tasks are shown in bold. + +tively impacted by adding Synth. Math-Alignment. +Thus, we can conclude that adding Synth. Math- +Alignment is beneficial for H6. + +Then, we experiment whether merging 'DPO +v1' and 'DPO v2' is beneficial. Unfortunately, +'DPO v1+v2' scores 73.21 in H6, which is worse +than 'DPO v2'. More importantly, the gain in +the GSM8K score from adding Synth. Math- +Alignment is gone, which is undesirable. One +reason for this could be that 'DPO v2' is a strict +improvement over 'DPO v1', unlike the case for +merging 'SFT v3' and 'SFT v4' where the models +had different strengths and weaknesses. + +Ablation on the SFT base models. When ap- +plying DPO, we start from a model that is already +instruction tuned ,i.e., the SFT base model and ab- +late on using different SFT base models. We use +Ultrafeedback Clean and Synth. Math-Alignment +datasets for this ablation. Each of the ablated mod- +els is trained as follows. 'DPO v2' uses 'SFT v3' +as the base SFT model, while 'DPO v3' uses 'SFT +v3+v4' as the SFT base model instead. + +Note that 'SFT v3+v4' has higher scores on all +tasks compared to 'SFT v3', and the gap is espe- +cially large for ARC (+1.45) and GSM8K (+2.43). +Surprisingly, the two models perform similarly in +terms of H6. A closer look at the scores for the +individual tasks shows only a small margin in the +GSM8K scores, and other task scores show little +difference. Thus, the performance gaps in certain +tasks in the SFT base models do not always carry +over to the alignment-tuned models. + +Ablation on different merge methods. From +Tab. 3, we saw that merging two models that have +different strengths can be beneficial to performance. + +To utilize this for the alignment-tuned model as +well, we train two models named 'Cand. 1' and +'Cand. 2' using the same training dataset and SFT +base model as 'DPO v2' and 'DPO v3' but with dif- +ferent hyper-parameters to maximize each model's +respective strengths. We compare 'Cand. 1' and +'Cand. 2' in Tab. 6 where we can see that 'Cand. 1' +has high GSM8K scores but relatively low scores +for the other tasks, whereas 'Cand. 2' has low +scores for GSM8K but high scores for the other +tasks. We merge these two models using various +methods and ablate the results in Tab.. 7. + +We use two merge methods: 1) Average (a, b), +where a and b denote the weighting for 'Cand. +1' and 'Cand. 2' when averaging weights and 2) +SLERP (Shoemake, 1985). We use (0.5, 0.5), (0.4, +0.6), and (0.6, 0.4) for Average (a, b). From Tab. 7, +we can see that the different merge methods have +little effect on the H6 scores. The scores for the +individual tasks also do not differ by much, suggest- +ing that as long as the merge candidates have suffi- +ciently different strengths, the exact merge method +may not be as crucial. Thus, we chose 'Merge v1' +as our SOLAR 10.7B-Instruct model. + +# 5 Conclusion + +We introduce SOLAR 10.7B and its fine-tuned vari- +ant SOLAR 10.7B-Instruct, which are depth up- +scaled (DUS) models with 10.7 billion parameters. +They show superior performance over models like +Llama 2, Mistral 7B, and Mixtral-7B-Instruct in es- +sential NLP tasks while maintaining computational +efficiency. Thus, DUS is effective in scaling-up +highly performant LLMs from smaller ones. With +more exploration, DUS could be further improved, +paving a new path to efficiently scaling LLMs. \ No newline at end of file diff --git a/benchmark/ground-truth/markdown-2026-03-25/01030000000191.md b/benchmark/ground-truth/markdown-2026-03-25/01030000000191.md new file mode 100644 index 0000000..399304b --- /dev/null +++ b/benchmark/ground-truth/markdown-2026-03-25/01030000000191.md @@ -0,0 +1,115 @@ +# Acknowledgements + +We would like to extend our gratitude to the teams +at Hugging Face, particularly Clementine Four- +rier, Lewis Tunstall, Omar Sanseviero, and Philipp +Schmid. Our appreciation also extends to the teams +at AWS, notably Ritesh Vajaria, Gal Oshri, Jay +Kwon, Brandon Lee, Effie Bae, and Rahul Sharma. +We are grateful to the teams at Korea Telecom +(KT), especially Jin Hyoung Lee, Jungsuk Park, +Sungjoon Park, Hong-rae Wang, Kyeongsoo Jung, +and Sunyoong Yoon, whose significant support has +been instrumental in ensuring the broad compati- +bility of our model. Additionally, we would like to +extend our thanks to the open community for their +invaluable contributions and feedback. + +# Limitations + +Our study on the Depth Up-Scaling (DUS) has im- +portant limitations and considerations. One key +limitation is the need for more thorough explo- +rations of hyperparameters used in the DUS ap- +proach. Namely, we removed m = 8 layers from +both ends of our base model, primarily due to hard- +ware limitations. However, we have not yet deter- +mined if this value is optimal for enhancing perfor- +mance. The extended time and cost of continued +pretraining made it challenging to conduct more +comprehensive experiments, which we aim to ad- +dress in future work through various comparative +analyses. + +In terms of the model's broader implications, +there are several points to note. The model's sig- +nificant computational demands for training and +inference might limit its use, especially for those +with restricted computational resources. Addition- +ally, like all machine learning models, it is vulnera- +ble to biases in its training data, which could lead +to skewed outcomes in certain situations. Further- +more, the substantial energy consumption required +for training and operating the model raises environ- +mental concerns, which are critical in the pursuit +of sustainable AI development. + +Lastly, while the fine-tuned variant of the model +shows improved performance in following instruc- +tions, it still requires task-specific fine-tuning for +optimal performance in specialized applications. +This fine-tuning process can be resource-intensive +and not always effective. Recognizing and address- +ing these limitations is essential for a comprehen- +sive understanding of the proposed Large Language +Model's capabilities and for guiding future research + +and development in the field of LLMs. + +# Ethics Statement + +We conscientiously address and emphasize the +commitment of SOLAR 10.7B in maintaining the +highest ethical standards. First, we highlight that +SOLAR 10.7B-Instruct has shown low levels of +data contamination in our evaluations, a testament +to our rigorous data handling and processing pro- +tocols. This aspect is crucial, as it underpins the +reliability and integrity of the results obtained from +SOLAR. + +Furthermore, during the course of our experi- +ments, we ensured that all setups and methodolo- +gies employed steer clear of any potential ethical +pitfalls. This preemptive consideration and avoid- +ance of ethically questionable practices underscore +our dedication to conducting research that is not +only innovative but also responsible. + +Additionally, we ensure that SOLAR complies +with general ethical considerations in all aspects +of its operation. This includes adherence to pri- +vacy norms, respect for intellectual property, and +ensuring the absence of bias in our algorithms. Our +commitment to these ethical principles is unwaver- +ing, and we believe it significantly contributes to +the credibility and societal acceptance of SOLAR. + +In conclusion, the ethical framework within +which SOLAR operates is robust and comprehen- +sive, ensuring that our advancements in this field +are not only scientifically sound but also ethically +responsible. + +# References + +Ian L Alberts, Lorenzo Mercolli, Thomas Pyka, George +Prenosil, Kuangyu Shi, Axel Rominger, and Ali +Afshar-Oromieh. 2023.

All these individuals contributed to the +creation of SOLAR 10.7B. + +# B Related Works and Background + +# B.1 Large Language Models + +Following the advent of context-based language +models, various studies have revealed a "scaling +law" (Kaplan et al., 2020; Hernandez et al., 2021; +Anil et al., 2023), demonstrating a positive corre- +lation between the size of model and training data +and model performance. This has led to the emer- +gence of Large Language Models (LLMs). Un- +like previous language models, LLMs possess the + +ability for In-context learning, including Zero-shot +learning (Radford et al., 2019) and Few-shot learn- +ing (Brown et al., 2020), allowing them to perform +new tasks without updating model weights. These +capabilities of LLMs, not evident in smaller mod- +els, are referred to as Emergent abilities (Wei et al., +2022a). + +# B.2 Mixture of Experts + +In the landscape of machine learning architectures, +the Mixture of Experts (MoE) models like (Shazeer +et al., 2017; Shen et al., 2019; Komatsuzaki et al., +2022) has gained attention for its capability to ad- +dress the challenges posed by complex and hetero- +geneous data. MoE models offer notable benefits, +including enhanced output diversity, allowing for +the capture of intricate patterns within the input +space. Moreover, their computational efficiency, +especially when implemented in a sparse form, has +made them valuable in scenarios where resource +constraints are a consideration (Shazeer et al., 2017; +Komatsuzaki et al., 2022). + +However, efficient implementation of MoE mod- +els poses a considerable challenge, primarily due to +the intricacies associated with dynamic routing and +load-imbalanced computation (Gale et al., 2023). +Existing hardware and software for deep learning, +such as TPUs and XLA compilers, often demand +static knowledge of tensor shapes, making MoE +implementation on TPU challenging. + +While GPU implementation offers more flexi- +bility, sparse computation compatibility becomes +a hurdle. Striking the right balance between fix- +ing the size of each expert to facilitate efficient +computation and maintaining model quality creates +a tradeoff between information preservation and +hardware efficiency. This tradeoff, in turn, necessi- +tates careful consideration during hyperparameter +tuning, adding a layer of complexity to the imple- +mentation of MoE models, potentially offsetting +their advantages. Given the formidable challenges +in MoE model implementation, it becomes almost +inevitable for researchers and practitioners to re- +sort to specialized tools and frameworks, such as +Tutel (Hwang et al., 2023) or Megablocks (Gale +et al., 2023). + +Departing from the horizontal expansion char- +acteristic of MoE models, the DUS method intro- +duces model scaling in the vertical dimension.

This shift in ap- +proach offers a unique and more straightforward +way of working, moving away from conventional +MoE challenges. Not only that, DUS also under- +goes continued pretraining to quickly recover per- +formance of the scaled model. + +# B.3 Prompt Engineering + +A key research area to harness the emergent abil- +ities of LLMs is prompt engineering. Prompt en- +gineering is the study of how to design inputs +(prompts) that enable LLMs to better perform spe- +cific tasks. A prime example of this research +is Chain-of-Thought (CoT) (Wei et al., 2022b), +which proposes CoT prompting that decomposes +multi-step problems into a series of intermedi- +ate reasoning steps. Moreover, efforts are under- +way to replace even such prompt engineering with +LLMs (Yang et al., 2023). + +# B.4 Instruction Tuning + +To enhance the steerability of LLMs, instruction +tuning (Wei et al., 2021) has emerged as a learning +technique. This involves fine-tuning LLMs using +data formatted as (instruction, input, output) for +various tasks (Wang et al., 2022). Instruction tuning +allows for targeted adjustments, providing a more +controlled and task-oriented improvement to the +model's capabilities. + +Before instruction tuning, existing methods +faced challenges in effectively guiding and control- +ling the behavior of large language models (Zhang +et al., 2023b). The sheer complexity of these mod- +els made it difficult to ensure precise and task- +oriented responses. The need for a more targeted +approach arose from the limitations of existing +methods, leading to the development of instruc- +tion tuning. This targeted approach enables better +control over the model's behavior, making it more +suitable for specific tasks and improving its overall +performance in alignment with user-defined objec- +tives. Therefore, instruction tuning is computation- +ally efficient and facilitates the rapid adaptation +of LLMs to a specific domain without requiring +extensive retraining or architectural changes. + +# B.5 Alignment Tuning + +LLM has been observed to generate sentences that +may be perceived as linguistically incongruent by +human readers since they learned not human inten- +tion, but only vast knowledge across various do- +mains in the pretraining step (Ziegler et al., 2019). + +To overcome this limitation and align with human +intentions, previous research (Ziegler et al., 2019) +have proposed Reinforcement Learning with Hu- +man Feedback (RLHF). RLHF operates by learning +a reward model based on human preferences, em- +ploying reinforcement learning to guide the LLM +towards prioritizing answers with the highest re- +ward scores. This process enhances the safety, +propriety, and overall quality of the generated re- +sponses. Despite demonstrating satisfactory per- +formance, RLHF encounters challenges such as +managing numerous hyperparameters and necessi- +tating the incorporation of multiple models (policy, +value, reward, and reference models). + +In response to these challenges, the supervised +fine-tuning based approaches have proposed, such +as Rank Responses to align Human Feedback +(RRHF) (Yuan et al., 2023), Reward rAnked Fine- +Tuning (RAFT) (Dong et al., 2023), and Direct +Policy Optimization (DPO) (Intel, 2023). They +avoid the complexities associated with reinforce- +ment learning while achieving empirical perfor- +mance comparable to RLHF. Among them, DPO +that we used directly guides the LLM to increase +the probability of positive responses and decrease +the probability of negative responses through a "di- +rect" approach. Interestingly, DPO demonstrates +more stable learning results compared to RLHF, +despite its simple training approach. + +# B.6 Data Contamination + +Recent researches (Zhou et al., 2023; Sainz et al., +2023; Golchin and Surdeanu, 2023; Deng et al., +2023) emphasize the need to measure whether a +specific benchmark was used to train the large lan- +guage models. There are three types of the data +contamination: guideline, raw text and annota- +tion (Sainz et al., 2023). Guideline contamination +occurs when a model accesses detailed annotation +guidelines for a dataset, providing advantages in +specific tasks, and its impact should be considered, +especially in zero and few-shot evaluations. Raw +text contamination occurs when a model has ac- +cess to the original text. Wikipedia is widely used +as a pretraining data, but also as a source for cre- +ating new datasets. The caution is advised in the +development of automatically annotated datasets +sourced from the web. Annotation contamina- +tion occurs when the annotations of the specific +benchmark are exposed during model training. \ No newline at end of file diff --git a/benchmark/ground-truth/markdown-2026-03-25/01030000000197.md b/benchmark/ground-truth/markdown-2026-03-25/01030000000197.md new file mode 100644 index 0000000..dcc27c7 --- /dev/null +++ b/benchmark/ground-truth/markdown-2026-03-25/01030000000197.md @@ -0,0 +1,87 @@ +# C Additional Information + +We present additional information for the sake of +space in the main paper. + +Filtered task names.

However, each trial -takes longer than in those single-presentation tasks, which makes experi- -ments more onerous. There are a few reasons why the roving-standard 2xSJ is -still worth considering. Firstly, it asks about synchrony explicitly (unlike the -TOJ) and by requiring relative judgements it reveals a point of maximal syn- -chrony perception (whereas the SJ and ternary tasks often reveal a range of -SOA values that are classified as synchronous). Secondly, it can be added in -to a single-presentation task (as a follow-up question every two trials), which -somewhat mitigates the burden of additional experimental time. Finally, a case -can be made that it will be more resistant to some forms of decision-level bias -(Morgan, Grant, Melmoth, & Solomon, 2015; Morgan, Melmoth, & Solomon, -2013). As with the other tasks I have described, code to fit data from the 2xSJ -accompanies this chapter.23 For further information, read the comments there -and consult Yarrow et al.

Interestingly, such projections were internalized by eighteenth-century British subjects in the fashionable “Turquerie” that allowed the wearers to display their wealth by wearing Oriental dress, turbans, ostrich plumes, long capes, veils, and flattering shalvars (figs. 4.9 and 4.10). Another infusion of Orientalism in the West, the tradition of painting European figures in Middle Eastern dress, becomes a form of cultural cross-dressing meant to suggest misuse of power or excessive wealth (fig. 4.11). Such cultural imports are difficult to be understood, to use Said’s qualification, as expressions of the Occident’s cultural “antipathy” toward the Orient; rather, they reflect the West’s attraction to a space that connotes difference understood as extraordinariness rather than inferiority. +Besides their connotations of magic, exoticism, and wealth, the things in the *Arabian Nights* are also rich bearers of cultural information: as Marina Warner correctly pointed out, “stories are lodged in goods” [85] and as such, they expand the reader’s* -misuse of power or excessive wealth (fig. 4.11). -Such cultural imports are difficult to be under- -stood, to use Said's qualification, as expressions of -the Occident's cultural "antipathy"84 toward the -Orient; rather, they reflect the West's attraction to a -space that connotes difference understood as ex- -traordinariness rather than inferiority. +--- -Besides their connotations of magic, exoticism, -and wealth, the things in the Arabian Nights are also -rich bearers of cultural information: as Marina War- -ner correctly pointed out, "stories are lodged in -goods"85 and as such, they expand the reader's - -84 Said, Orientalism, 260. -85 Marina Warner, introduction to Stranger Magic: -Charmed States and the Arabian Nights (London: Chat- -to & Windus, 2011), 8. \ No newline at end of file +**Footnotes** +84.

Thus, this is definitely a weaker statement, but it can nevertheless be argued that it can be used to explain the time asymmetry that we observe, referring to a kind of anthropic principle: it is an obvious observational fact that we live in a universe with low entropy at at least one end.

The advantage of using a critical Reynolds number, instead of critical velocity, is that the results of the experiments are applicable to all Newtonian fluid flows in pipes with a circular cross-section. + +| Temperature (degree C) | Kinematic viscosity v (m²/s) | Temperature (degree C) | Kinematic viscosity v (m²/s) | +|:---:|:---:|:---:|:---:| +| 0 | 1.793E-06 | 25 | 8.930E-07 | +| 1 | 1.732E-06 | 26 | 8.760E-07 | +| 2 | 1.674E-06 | 27 | 8.540E-07 | +| 3 | 1.619E-06 | 28 | 8.360E-07 | +| 4 | 1.522E-06 | 29 | 8.180E-07 | +| 5 | 1.520E-06 | 30 | 8.020E-07 | +| 6 | 1.474E-06 | 31 | 7.850E-07 | +| 7 | 1.429E-06 | 32 | 7.690E-07 | +| 8 | 1.386E-06 | 33 | 7.530E-07 | +| 9 | 1.346E-06 | 34 | 7.380E-07 | +| 10 | 1.307E-06 | 35 | 7.240E-07 | +| 11 | 1.270E-06 | 36 | 7.110E-07 | +| 12 | 1.235E-06 | 37 | 6.970E-07 | +| 13 | 1.201E-06 | 38 | 6.840E-07 | +| 14 | 1.169E-06 | 39 | 6.710E-07 | +| 15 | 1.138E-06 | 40 | 6.580E-07 | +| 16 | 1.108E-06 | 45 | 6.020E-07 | +| 17 | 1.080E-06 | 50 | 5.540E-07 | +| 18 | 1.053E-06 | 55 | 5.110E-07 | +| 19 | 1.027E-06 | 60 | 4.760E-07 | +| 20 | 1.002E-06 | 65 | 4.430E-07 | +| 21 | 9.780E-07 | 70 | 4.130E-07 | +| 22 | 9.550E-07 | 75 | 3.860E-07 | +| 23 | 9.330E-07 | 80 | 3.630E-07 | +| 24 | 9.110E-07 | 85 | 3.420E-07 | + +*Figure 7.2: Kinematic Viscosity of Water at Atmospheric Pressure.* diff --git a/benchmark/ground-truth/markdown/01030000000111.md b/benchmark/ground-truth/markdown/01030000000111.md index 3e3dab5..e87983d 100644 --- a/benchmark/ground-truth/markdown/01030000000111.md +++ b/benchmark/ground-truth/markdown/01030000000111.md @@ -1,45 +1,29 @@ -b) -24 mm ⌀ -8 mm ⌀ 16 mm ⌀ -a) -Cylindrical vessel -3-way valve -Outlet valve -c) d) -Inlet pipe -15-degree angled tubes 60-degree angled tubes +**Figure 8.1:** a) P6238 CUSSONS free and forced vortex apparatus, b) push-in orifices, c) free vortex measuring caliper, d) force vortex measuring probes -Figure 8.1: a) P6238 CUSSONS free and forced vortex apparatus, b) push-in orifices, c) free vortex measuring caliper, d) force vortex -measuring probes +--- -# 7.

If the paucity of female role models discourages females from seeing the relevance of fishing to them, these examples should inspire. -Frederick Buller (2013) chronicled the very long list of large -Atlantic Salmon caught by female anglers, which are -outnumbered 200 to 1 by male salmon anglers.

Long description. +Creel limits are one of many elements that may be used by anglers to define fishing success. When more fish are harvested per trip, anglers rate fishing higher. High creel limits may cause anglers to have unrealistic expectations about the potential supply of fish compared to the demand (Cook et al. 2001). Creel limit reductions may be unsuccessful in reducing angler harvest or affecting fish populations. The hypothetical angler success graph (Figure 10.5) demonstrates that a reduction in creel from 8 to 4 would affect only a few trips and result in a small harvest reduction. Furthermore, creel limits are applied on a per-angler basis, so they cannot control total harvest if total fishing effort increases or if noncompliance is high. Finally, since anglers have a variety of motivations, they likely respond differently to regulation changes (Beard et al. 2011). -Creel limits are one of many elements that may be used by anglers to define fishing success.

In Minnesota, anglers were slightly more successful, where 27.2% of angler trips ended with a harvest of at least one Walleye and about 1% harvesting a limit.

New technologies, such as sonar, have made tuna fishing much more effective. In response, the use of spotter planes is banned for fishing Atlantic Bluefin Tuna in the Mediterranean (Di Natale 2020).

IRAS was equipped with a 0.6-meter telescope cooled to a temperature of less than 10 K. For the first time, the infrared sky could be seen as if it were night, rather than through a bright foreground of atmospheric and telescope emissions. IRAS carried out a rapid but comprehensive survey of the entire infrared sky over a 10-month period, cataloging about 350,000 sources of infrared radiation. Since then, several other infrared telescopes have operated in space with much better sensitivity and resolution due to improvements in infrared detectors. The most powerful of these infrared telescopes is the 0.85-meter Spitzer Space Telescope, which launched in 2003. A few of its observations are shown in [Figure 2](#). With infrared observations, astronomers can detect cooler parts of cosmic objects, such as the dust clouds around star nurseries and the remnants of dying stars, that visible-light images don’t reveal. -The first orbiting infrared observatory, launched in 1983, was the -Infrared Astronomical Satellite (IRAS), built as a joint project by -the United States, the Netherlands, and Britain.

First, seed math data are collected from -the Math (Hendrycks et al., 2021) dataset only, to -avoid contamination with commonly used bench- -mark datasets such as GSM8K (Cobbe et al., 2021). -Then, using a process similar to MetaMath (Yu -et al., 2023), we rephrase the questions and an- -swers of the seed math data. We use the resulting -rephrased question-answer pairs as a QA dataset - -and call it 'Synth. Math-Instruct'. - -Alignment tuning. In the alignment tuning stage, -the instruction-tuned model is further fine-tuned to -be more aligned with human or strong AI (e.g., -GPT4 (OpenAI, 2023)) preferences using direct -preference optimization (DPO) (Rafailov et al., -2023). Similar to the instruction tuning stage, we -use mostly open-source datasets but also synthe- -size a math-focused alignment dataset utilizing the -'Synth.

We take advantage of the fact that -the rephrased question-answer pairs in Synth. -Math-Instruct data are beneficial in enhancing the -model's mathematical capabilities (see Sec. 4.3.1). -Thus, we speculate that the rephrased answer to the -rephrased question is a better answer than the orig- -inal answer, possibly due to the interim rephrasing -step. Consequently, we set the rephrased question -as the prompt and use the rephrased answer as the -chosen response and the original answer as the re- -jected response and create the {prompt, chosen, -rejected} DPO tuple. We aggregate the tuples from -the rephrased question-answer pairs and call the -resulting dataset 'Synth. Math-Alignment'. - -# 4 Results - -# 4.1 Experimental Details - -Training datasets.

We also -report the size of the models in units of billions of parameters. The type indicates the training stage of the model -and is chosen from {Pretrained, Instruction-tuned, Alignment-tuned}. Models based on SOLAR 10.7B are colored -purple. The best scores for H6 and the individual tasks are shown in bold. - -We reformatted the instruction datasets with an -Alpaca-styled chat template. For datasets such as -OpenOrca, which are derived from FLAN (Long- -pre et al., 2023), we filter data that overlaps with -the benchmark datasets (see Tab. 8 in Appendix. C -for more information). The alignment datasets are -in the {prompt, chosen, rejected} triplet format. -We preprocess the alignment datasets following -Zephyr (Tunstall et al., 2023). - -Evaluation. In the HuggingFace Open LLM -Leaderboard (Beeching et al., 2023), six types of -evaluation methods are presented: ARC (Clark -et al., 2018), HellaSWAG (Zellers et al., 2019), -MMLU (Hendrycks et al., 2020), TruthfulQA (Lin -et al., 2022), Winogrande (Sakaguchi et al., 2021), -and GSM8K (Cobbe et al., 2021).

One key -limitation is the need for more thorough explo- -rations of hyperparameters used in the DUS ap- -proach. Namely, we removed m = 8 layers from -both ends of our base model, primarily due to hard- -ware limitations. However, we have not yet deter- -mined if this value is optimal for enhancing perfor- -mance. The extended time and cost of continued -pretraining made it challenging to conduct more -comprehensive experiments, which we aim to ad- -dress in future work through various comparative -analyses. +Our study on the Depth Up-Scaling (DUS) has important limitations and considerations.

The sheer complexity of these models made it difficult to ensure precise and task-oriented responses. The need for a more targeted approach arose from the limitations of existing methods, leading to the development of instruction tuning. This targeted approach enables better control over the model’s behavior, making it more suitable for specific tasks and improving its overall performance in alignment with user-defined objectives. Therefore, instruction tuning is computationally efficient and facilitates the rapid adaptation of LLMs to a specific domain without requiring extensive retraining or architectural changes. -Before instruction tuning, existing methods -faced challenges in effectively guiding and control- -ling the behavior of large language models (Zhang -et al., 2023b).

However, each trial takes longer than in those single-presentation tasks, which makes experiments more onerous. There are a few reasons why the roving-standard 2xSJ is still worth considering. Firstly, it asks about synchrony explicitly (unlike the toj) and by requiring relative judgements it reveals a point of maximal synchrony perception (whereas the sj and ternary tasks often reveal a range of soa values that are classified as synchronous). Secondly, it can be added in to a single-presentation task (as a follow-up question every two trials), which somewhat mitigates the burden of additional experimental time. Finally, a case can be made that it will be more resistant to some forms of decision-level bias (Morgan, Grant, Melmoth, & Solomon, 2015; Morgan, Melmoth, & Solomon, 2013). As with the other tasks I have described, code to fit data from the 2xSJ accompanies this chapter.23 For further information, read the comments there and consult Yarrow et al.

Go to **Account Settings → API Tokens → New Token**. - - Token name: `edgeparse-github-actions` - - Scope: `publish-new` + `publish-update` (do **not** grant `yank`) -3. Copy the token — shown only once. -4. Add to GitHub: secret name `CARGO_REGISTRY_TOKEN`. - -For **local publishing**, export the token: - -```bash -export CARGO_REGISTRY_TOKEN=<token> -make publish-rust -``` - -**Verify locally:** - -```bash -CARGO_REGISTRY_TOKEN=<token> cargo publish -p edgeparse-core --dry-run -``` - -**Publish order matters.** `pdf-cos` is a local dependency of `edgeparse-core`, and `edgeparse-core` is a dependency of `edgeparse-cli`. The workflow publishes in order with 30-second waits for the crates.io index to propagate: -1. `pdf-cos` (internal lopdf fork) -2. `edgeparse-core` -3. `edgeparse-cli` - -**Reserved file gotcha.** If `pdf-cos` was extracted from a `.crate` archive, it may contain `.cargo_vcs_info.json`.

In GitHub, create the `pypi` **Environment** (Settings → Environments → New environment). No secrets required. - -The `release-python.yml` workflow uses `pypa/gh-action-pypi-publish@release/v1` with `id-token: write` permission. - -**Local publishing** uses a PyPI API token instead of OIDC: - -```bash -# Create a PyPI API token at https://pypi.org/manage/account/token/ -export PYPI_PASSWORD=pypi-<your-api-token> -make publish-python -``` - -The Makefile uses `--username __token__ --password "$PYPI_PASSWORD"` — the literal string `__token__` is required when authenticating with an API token. - -**Verify wheels locally (dry-run):** - -```bash -make publish-python-dry -``` - ---- - -### 3. npm — Access Token - -**Required for:** `release-node.yml` - -The npm package is `edgeparse` (unscoped). Platform-specific packages (`edgeparse-darwin-arm64`, etc.) are also unscoped. - -**Steps (one-time):** - -1. Sign in to [npmjs.com](https://www.npmjs.com) as the publisher account. -2. Go to **Account → Access Tokens → Generate New Token → Classic Token**. - - Token type: **Automation** (bypasses 2FA prompts in CI) - - Token name: `edgeparse-github-actions` -3. Copy the token. -4. Add to GitHub: secret name `NPM_TOKEN`. - -> **⚠️ IMPORTANT — Classic token, not Granular token:** A Granular Access Token only grants access to packages you explicitly list at creation time. Publishing 6 packages (`edgeparse` + 5 platform packages) requires either a **Classic Automation token** (access to all packages you own) or a Granular token with all 6 packages listed individually. If you see `E403 Forbidden` on platform packages but the main `edgeparse` publishes fine, your token was created as Granular with only `edgeparse` in scope — recreate it as a Classic Automation token. - -> **Token rotation:** npm Granular Access Tokens expire. Rotate before expiry at [npmjs.com → Access Tokens](https://www.npmjs.com/settings/~/tokens). - -**Verify locally:** - -```bash -NODE_AUTH_TOKEN=<token> npm whoami -cd sdks/node && npm pack --dry-run -# Or via Makefile: -make publish-node-dry -``` +| macOS Apple Silicon | cp310, cp311, cp312, cp313 | +| Windows x86_64 | cp310, cp311, cp312, cp313 | +| Source distribution | sdist | --- -### 4.

Bump Node.js package versions cd sdks/node -# Update package.json and npm/*/package.json to new version - -# 3. Bump Python version -# Update sdks/python/pyproject.toml - -# 4. Commit and push -git add -A -git commit -m "chore: bump version to 0.2.0" -git push origin main - -# 5. Tag and push — triggers all five release workflows -git tag v0.2.0 -git push origin v0.2.0 +npm ci +cargo build --manifest-path ../../crates/edgeparse-node/Cargo.toml --release +# Copy the host-specific addon into the matching local package before testing. +# Example shown here for Apple Silicon: +cp ../../target/release/libedgeparse_node.dylib npm/darwin-arm64/edgeparse-node.darwin-arm64.node +npm install --no-save file:./npm/darwin-arm64 +npm run build:ts +npm test +cd ../.. + +cd benchmark +uv run python run.py --check-regression +cd .. ``` -The tag format must match `v[0-9]+.[0-9]+.[0-9]+`. The Rust workflow verifies the tag version matches `edgeparse-core`'s Cargo.toml version and fails fast if they diverge. - -### Option B — Local publishing (Makefile, no CI) - -```bash -# Set credentials in environment -export CARGO_REGISTRY_TOKEN=<crates-io-token> -export PYPI_PASSWORD=pypi-<api-token> # note: --username __token__ is used automatically -export NPM_TOKEN=<npm-granular-access-token> - -# Full publish: crates + PyPI + npm + CLI binaries + Homebrew -make publish-all - -# Or target-by-target: -make publish-rust # → crates.io -make publish-python # → PyPI -make publish-node # → npm -make publish-cli # → GitHub Release (binaries) -make publish-brew # → Homebrew tap (run after publish-cli) -``` +Optional dry runs: -Dry-run any target first: ```bash make publish-rust-dry make publish-python-dry make publish-node-dry +make publish-wasm-dry make publish-cli-dry make publish-brew-dry ``` --- -## Workflow Reference - -### `ci.yml` — Continuous Integration - -**Triggers:** Every push to `main`, every PR targeting `main` - -| Job | What it does | -|-----|-------------| -| `rust` | `cargo build + test + clippy + fmt` on ubuntu, macos, windows | -| `python` | `maturin develop --release + pytest tests/` | -| `node` | `npm ci + cargo build + npm run build + npm test` | -| `security` | `cargo audit + cargo deny check` | - -### `release-rust.yml` — crates.io - -**Triggers:** `v*.*.*` tag push - -| Step | Detail | -|------|--------| -| Version check | Tag version must match `edgeparse-core` Cargo.toml version | -| CHANGELOG | `git-cliff` generates release notes from conventional commits | -| Publish pdf-cos | Internal lopdf fork — must be published before edgeparse-core | -| Wait 30s | crates.io index propagation delay | -| Publish edgeparse-core | Core library | -| Wait 30s | Index propagation | -| Publish edgeparse-cli | CLI crate (binary) | -| GitHub Release | Created with generated release notes | - -### `release-python.yml` — PyPI - -**Triggers:** `v*.*.*` tag push +## Tag Release Flow -| Job | Detail | -|-----|--------| -| `build-wheels` | Matrix: 5 platforms.

Tag the merge commit on main +git checkout main +git pull --ff-only origin main +git tag v0.2.1 +git push origin v0.2.1 +``` -> **Note:** The Docker build uses `rust:1-slim-bookworm` (latest stable) as the builder image. The workspace `rust-version` for the CLI crate is pinned at ≥ 1.85, but transitive dependencies (`time`, `image`) may require a newer compiler. Using `rust:1` (not a pinned version) avoids compatibility issues. Additionally, the build uses `find crates/ -name '*.rs' -exec touch {} +` after copying real sources to ensure Cargo recompiles all crates (not just the empty stubs used for caching). +The tag must match `v[0-9]+.[0-9]+.[0-9]+`. The Rust and WASM release +workflows verify that the tag version matches the workspace version and fail +fast on mismatches. --- -## Troubleshooting - -### crates.io: "crate version already exists" - -You cannot overwrite a version on crates.io.

Using `rust:1` (latest stable) prevents `rustc X.Y.Z is not supported by ...` errors when deps advance. | -| `sed`-strip python/node/wasm workspace members before Docker cache warmup | These crates pull in `napi-rs`, `wasm-bindgen`, `pyo3` — dependencies incompatible with the CLI-only Docker build. Stripping them from `Cargo.toml` before the dummy `cargo build` avoids version conflicts in the cache layer. | -| `-i python3.10 python3.11 python3.12 python3.13` for all maturin platforms | For Linux manylinux cross-builds, `actions/setup-python` does not affect the containerised maturin build. Explicit `-i` flags are required for all matrix entries to avoid "Couldn't find any python interpreters" failures. | -| Unscoped `edgeparse` npm package | No npm organization required; avoids org overhead. All platform packages (`edgeparse-darwin-arm64`, etc.) are also unscoped. | -| PyPI OIDC for CI, API token for local Makefile | OIDC tokens expire in minutes and are scoped per run — ideal for CI. The Makefile uses a long-lived API token for convenient local publishing. | -| `pdf-cos` published separately before `edgeparse-core` | `edgeparse-core` depends on `pdf-cos` from crates.io. Publishing first ensures the index is available when the dependent crate is validated. | -| 30-second wait steps between crates | crates.io index updates are eventually consistent. 30 seconds is sufficient for the dependency to appear before the dependent crate is validated. | -| `environment: npm` / `environment: pypi` on publish jobs | Enables GitHub Environment protection rules (optional reviewers, deployment history). | -| Separate `release-cli.yml` for binaries + Homebrew | CLI binary publishing is unrelated to crates.io and has its own lifecycle. Decoupling avoids blocking the Rust publish on cross-compilation. The Homebrew formula depends on the CLI artifacts, so it lives in the same workflow. | -| `HOMEBREW_TAP_TOKEN` instead of `GITHUB_TOKEN` for tap push | `GITHUB_TOKEN` only has write access to the current repository. A dedicated PAT scoped to `raphaelmansuy/homebrew-edgeparse` is required to push the formula. | +Use `cargo-zigbuild` plus `zig`. The release workflows already do this for the +Linux ARM64 and Windows targets. diff --git a/docs/09-wasm-sdk.md b/docs/09-wasm-sdk.md index d90211d..6107206 100644 --- a/docs/09-wasm-sdk.md +++

parser output: + +- `01030000000090` and sibling pages `01030000000089/88` exposed a stale-evaluation blind spot in the multi-engine benchmark workflow. +- The current evaluator already penalized these docs correctly, but stale `edgepdf/evaluation.json` artifacts predated text metrics and schema versioning, so the bad page still appeared artificially strong. +- Benchmark tooling now tags evaluation payloads with a schema version, detects incomplete payloads, and refreshes stale engine evaluations through `run.py --skip-parse`. + +Sixth-pass closeout then tightened the text metrics

table regions, using raster line projections to detect the grid and cell-wise OCR to populate the recovered table. +- The first broader variant also injected OCR caption/text chunks and improved `TEDS`, but the full board fell to `overall 0.7520`; that variant was rejected and rolled back before landing. +- The retained narrow variant kept only the bordered-raster-table recovery and raised the live board to `overall 0.7596`, `NID 0.8739`, `TEDS 0.5422`, `TQS 0.8966`, `TD F1 0.9333`, and `speed 0.0335 s/doc`. +- The anchor document `01030000000122` moved from `overall 0.5645` to

closeout focused on first-principles geometry and metric visibility rather than benchmark-specific rendering: + +- Implemented source-level geometric augmentation for left-stub panel tables inside `cluster_table_detector.rs`, validated by a new synthetic detector test and the full cluster-table detector suite. +- Added `token_boundary_f1`, a symmetric character-aligned whitespace-boundary metric that penalizes both split words and run-together words, and upgraded benchmark payloads to schema `v4`. +- Wired the new metric through `evaluation.json`, CSV export, terminal reports, and HTML reports so benchmark blind spots are visible without manual inspection. +- The refreshed full-corpus board under schema `v4` is: `overall 0.7568`, `NID 0.8698`, `TEDS 0.5237`, `MHS 0.4953`, `PBF 0.4953`, `SBF 0.5002`, `TQS 0.8961`, `ROUGE-1 0.9189`, `ROUGE-2 0.8908`, `ROUGE-L 0.8846`, `BLEU-4 0.8436`, `word_fragmentation_score 0.9243`, `word_boundary_integrity_score 0.9358`,

`text_quality_score` now includes `token_boundary_f1`. +- The new metric materially clarifies failure shape on the live frontier: `01030000000182` reports `token_boundary_f1 0.4635` and `01030000000187` reports `0.1671`, exposing boundary collapse that prior ROUGE/BLEU-weighted summaries understated. + +Current frontier after the twelfth pass: + +- `01030000000141`: image-first extraction collapse +- `01030000000187`: grouped-header table ownership collapse +- `01030000000182`: partial panel-table ownership with duplicated residual text +- `01030000000090`: relatively high lexical scores but still visible whitespace-boundary drift + +Latest continuation slice after the twelfth pass: + +- `01030000000187` was re-audited against the live release output and the grouped-header source signal was confirmed to be present upstream; the active failure was markdown header-row flattening, not detector absence. +- `output/markdown.rs` now preserves grouped header bands generically instead of concatenating them into strings such as `Instruction OpenOrca` and `Alignment Ultrafeedback Cleaned`. +- Benchmark evaluation payloads were upgraded again to schema `v5` with `table_cell_occupancy_f1`, a structure-sensitive metric that scores non-empty table-cell occupancy over `(table,row,column)` coordinates. +- On targeted `00187` evaluation, the new renderer lifted `TEDS_S` from `0.6098` to `0.6585`; the new occupancy metric reports `0.5538` on the preserved-header output and makes the structural repair visible even when lexical whitespace metrics remain mostly unchanged. +- No full-corpus benchmark board has been locked for this slice yet; this was a bounded frontier repair plus metric-system improvement. + +Latest continuation slice after the thirteenth pass: + +- `01030000000141` was re-audited as a native-text-starved but geometry-rich image-first infographic. `pdftotext -layout` produced almost no useful content, while the rendered page and legacy JSON preserved ten bordered card regions with recoverable page geometry. +- Landed change: `raster_table_ocr.rs` now includes a generic page-raster enrichment path that rasterizes the full page once, maps existing empty bordered-table cells into raster coordinates, OCRs each empty cell crop, and injects recovered text back into the corresponding table cells. +- The recovery is geometry-driven rather than benchmark-string-driven: activation is bounded by page text sparsity, empty-table coverage, and existing table ownership; semantic `Table` wrappers and direct `TableBorder` elements are both supported. +- `output/markdown.rs` now adds a generic infographic-card projection for narrow-left / wide-right two-column bordered cards, so recovered numbered cards render as numbered prose items instead of pipe tables. +- Focused validation on `00141` showed a strong retained local gain: `overall 0.1430 -> 0.4861`, `NID 0.0413 -> 0.5441`, `BLEU-4 0.6613`, `ROUGE-1 0.7774`, `ROUGE-L 0.4746`, and `text_quality_score 0.6919`. +- A later OCR-cleanup variant was explicitly rejected because it reduced the measured score; only the stronger generic page-raster OCR + card-projection path was retained. +- No full-corpus benchmark board has been locked for this slice yet; the retained work is a source-signal frontier improvement plus a committed checkpoint for the next optimization wave. + +Latest continuation slice after the fourteenth pass: + +- Another 50 OODA loops were executed on `01030000000141` after the `a5f0cfa` checkpoint, still constrained to first-principles geometry and source-signal improvements rather than benchmark-specific string repair. +- The main finding was real but not yet board-positive: 200-DPI card crops materially improve OCR over the default raster, and Tesseract TSV reveals that many remaining junk tokens are sparse edge-only lines formed by connector marks and decorative shapes rather than true sentence content. +- A bounded experimental branch used higher-DPI page rasterization, wide-cell TSV line reconstruction, and narrow-cell OCR context tuning. This cleaned some prose and improved some local text-shape metrics, but it also destabilized card numbering and mixed-table projection on the page. +- Best experimental rerun reached `overall 0.4819`, `NID 0.5393`, `ROUGE-1 0.7980`, `ROUGE-L 0.4988`, and `text_quality_score 0.6842`, which still underperformed the retained thirteenth-slice checkpoint (`overall 0.4861`, `TQS 0.6919`). +- Result: the entire fourteenth-pass parser branch was rejected and reverted. The retained codebase stays at the committed `a5f0cfa` state, while the new geometric findings are preserved as guidance for the next `00141` OCR-fidelity attempt. + +## Cohort Summary + +- `NID
