OMEGA: A Structured Math Benchmark to Probe the Reasoning Limits of LLMs


Introduction to Generalization in Mathematical Reasoning

Massive-scale language fashions with lengthy CoT reasoning, corresponding to DeepSeek-R1, have proven good outcomes on Olympiad-level arithmetic. Nevertheless, fashions skilled by way of Supervised Positive-Tuning or Reinforcement Studying rely on restricted strategies, corresponding to repeating identified algebra guidelines or defaulting to coordinate geometry in diagram issues. Since these fashions comply with discovered reasoning patterns fairly than displaying true mathematical creativity, they face challenges with advanced duties that demand unique insights. Present math datasets are poorly suited to analyzing math expertise that RL fashions can study. Massive-scale corpora combine a variety of math questions various in subject and problem, making it difficult to isolate particular reasoning expertise.

Limitations of Present Mathematical Benchmarks

Present strategies, corresponding to out-of-distribution generalization, give attention to dealing with check distributions that differ from coaching information, which is essential for mathematical reasoning, bodily modeling, and monetary forecasting. Compositional generalization strategies goal to assist fashions systematically mix discovered expertise. Researchers have created datasets by way of varied strategies to benchmark mathematical skills, which embrace hiring people to put in writing issues like GSM8K and MinervaMath, amassing examination questions corresponding to AIME and OlympiadBench, and scraping and filtering examination corpora like NuminaMath and BigMath. Nevertheless, these approaches both lack enough problem for contemporary LLMs or fail to offer evaluation granularity.

Introducing OMEGA: A Managed Benchmark for Reasoning Abilities

Researchers from the College of California, Ai2, the College of Washington, and dmodel.ai have proposed OMEGA, a benchmark designed to guage three dimensions of Out-of-Distribution generalization, impressed by Boden’s typology of creativity. It creates matched coaching and check pairs designed to isolate particular reasoning expertise throughout three dimensions: Exploratory, Compositional, and Transformative. OMEGA’s check and practice issues are constructed utilizing fastidiously engineered templates, permitting exact management over range, complexity, and the particular reasoning methods required for options. Furthermore, it employs 40 templated drawback turbines throughout six mathematical domains: arithmetic, algebra, combinatorics, quantity concept, geometry, and logic & puzzles.

Analysis on Frontier LLMs and Reinforcement Studying Setup

Researchers consider 4 frontier fashions, together with DeepSeek-R1, Claude-3.7-Sonnet, OpenAI-o3-mini, and OpenAI-o4-mini, throughout completely different complexity ranges. For RL generalization experiments, the framework applies the GRPO algorithm on 1,000 coaching issues utilizing Qwen2.5-7B-Instruct and Qwen2.5-Math-7B fashions. Exploratory generalization trains on restricted complexity ranges and evaluates on larger complexity issues. Compositional generalization entails coaching fashions on particular person expertise in isolation and testing their skill to mix and apply these expertise successfully. Transformational generalization trains on typical answer approaches and evaluates efficiency on issues that want unconventional methods.

Efficiency Observations and Mannequin Habits Patterns

Reasoning LLMs are likely to carry out worse as drawback complexity will increase, typically discovering appropriate options early however spending too many tokens on pointless verification. RL utilized solely on low-complexity issues enhances generalization to medium-complexity issues, with bigger positive factors on in-domain examples than out-of-distribution ones, indicating RL’s effectiveness at reinforcing acquainted patterns. As an illustration, within the Zebra Logic area, the bottom mannequin achieves solely 30% accuracy. Nevertheless, RL coaching elevated efficiency by 61 factors on in-domain examples and 53 factors on out-of-distribution examples with out SFT.

Conclusion: Towards Advancing Transformational Reasoning

In conclusion, researchers launched OMEGA, a benchmark that isolates and evaluates three axes of out-of-distribution generalization in mathematical reasoning: explorative, compositional, and transformative. The empirical examine reveals three insights: (a) RL fine-tuning considerably improves efficiency on in-distribution and exploratory generalization duties, (b) RL’s advantages for compositional duties are restricted, and (c) RL fails to induce genuinely new reasoning patterns. These findings spotlight a basic limitation: RL can amplify problem-solving breadth and depth, nevertheless it falls brief in enabling the inventive leaps important for transformational reasoning. Future work ought to discover curriculum scaffolding and meta-reasoning controllers.
