This Ai Paper Introduces The Kolmogorov-test: A Compression-as-intelligence Benchmark For Evaluating Code-generating Language Models

Compression is simply a cornerstone of computational intelligence, profoundly rooted successful nan mentation of Kolmogorov complexity, which defines nan minimal programme needed to reproduce a fixed sequence. Unlike accepted compression methods that look for repetition and redundancy, Kolmogorov’s model interprets compression arsenic a problem of discovering system patterns done programmatic representation. While nan mentation promises optimal compression, its uncomputability poses a important hurdle. Nevertheless, nan emergence of ample connection models tin of codification procreation opens an intriguing opportunity to trial really intimately modern systems tin approximate this theoretical perfect by reasoning done codification alternatively than shape matching.

A halfway rumor arises from nan limitations of existent devices successful compressing information sequences utilizing concise, executable code. Models often replicate inputs alternatively than make programs that reproduce them, indicating a spread successful existent shape understanding. This becomes particularly evident erstwhile dealing pinch real-world audio, text, aliases DNA sequences, wherever analyzable logical structures must beryllium uncovered to execute businesslike compression. The main situation is ensuring nan exemplary replicates nan series and uses a minimal and logical group of instructions. Furthermore, though synthetic training information is useful for controlled evaluation, it often fails to support robust generalization to earthy data, which is basal for applicable applications.

Several compression devices exist, ranging from accepted algorithms for illustration GZIP to newer neural compression systems. GZIP remains a beardown baseline, particularly for agelong aliases repetitive sequences, owed to its effective encoding of statistical regularities. More recently, connection modeling approaches person integrated pinch arithmetic coding, utilizing prediction probabilities to compress input data. However, these methods typically require entree to nan afloat exemplary weights astatine decoding time, limiting their ratio and applicability. Prompted code-generating models for illustration GPT-4 and LLaMA person besides been evaluated successful zero-shot settings to make Python programs that reproduce input sequences. Yet, they often nutrient lengthy, imprecise codification pinch constricted success, peculiarly erstwhile faced pinch unseen aliases analyzable sequences.

Researchers from Meta AI and Tel Aviv University introduced nan Kolmogorov-Test (KT), a benchmark for assessing nan reasoning capacity of code-generating connection models. The trial evaluates a model’s expertise to make nan shortest programme that outputs a fixed input sequence. Unlike emblematic benchmarks, KT emphasizes logical creation and programme procreation complete predictive matter modeling. Sequences see earthy information from audio (LibriSpeech), matter (Wikipedia enwik9), and DNA (GRCh38), arsenic good arsenic synthetic sequences generated done a custom-designed domain-specific connection (DSL). This DSL supports building system sequences by composing operations for illustration scope creation, series modification, merging, and filtering.

The researchers developed an automated model to make millions of synthetic program-sequence pairs utilizing this DSL. These programs past train and measure models, including ample pre-trained and specifically trained ones for illustration SEQCODER. To measurement performance, nan squad employed metrics specified arsenic accuracy—whether nan generated programme reproduces nan sequence—and precision—how concise nan correct programme is compared to GZIP compression. The trial progressive compressing sequences of varying lengths, pinch synthetic sequences averaging 76 bytes and existent sequences capped astatine 128.

Results showed that moreover nan astir powerful models struggled. GPT-4 achieved 69.5% accuracy connected high-quality audio but dropped to 36.4% for 8-bit audio and 50.3% for DNA data. LLaMA-3.1-405B performed worse, pinch accuracies arsenic debased arsenic 3.9% for audio and only 24.8% for DNA. In synthetic data, SEQCODER-8B reached 92.5% accuracy pinch a precision people of 0.56, outperforming accepted devices for illustration GZIP. However, its accuracy connected real-world information remained adjacent zero. This discrepancy illustrates nan trouble successful transferring occurrence from synthetic benchmarks to much varied and noisy real-world sequences, highlighting nan limitations of existent training regimes and prompting nan request for caller strategies.

Overall, this investigation intelligibly outlines nan complexity of compression via codification generation. The KT benchmark provides a rigorous and divers exemplary reasoning and building nickname test, exposing nan stark disagreement betwixt synthetic learning environments and real-world applications. The introduced methodology and trial group a precocious barroom for early models aiming to unify reasoning pinch compression, but important invention is still required to meet this challenge.
