Mathematical reasoning is important for problem-solving and decision-making, significantly in giant language fashions (LLMs). Evaluating LLMs’ mathematical reasoning normally focuses on the ultimate outcome quite than the reasoning course of intricacies. Present methodologies, just like the OpenLLM leaderboard, primarily use general accuracy, probably overlooking logical errors or inefficient steps. Enhanced analysis approaches are essential to uncover underlying points and enhance LLMs’ reasoning.
Present approaches usually consider mathematical reasoning in LLMs by evaluating closing solutions with floor fact and computing general accuracy. Nonetheless, some strategies assess reasoning high quality by evaluating generated answer steps with reference ones. Regardless of datasets offering floor fact, numerous reasoning paths to the identical reply problem reliance on any single reference. Prompting-based strategies instantly ask LLMs, usually GPT-4, to guage generated options, however their excessive computational price and transparency points hinder the practicality of iterative mannequin growth.
Researchers from Shanghai Jiao Tong College, Shanghai Synthetic Intelligence Laboratory, Yale College, Carnegie Mellon College, and Generative AI Analysis Lab (GAIR) launched REASONEVAL, a brand new strategy to evaluating reasoning high quality past final-answer accuracy. It makes use of validity and redundancy metrics to characterize reasoning steps’ high quality, which is robotically assessed by accompanying LLMs. REASONEVAL depends on base fashions with sturdy mathematical information, educated on high-quality labeled information, to instantiate its analysis framework.
REASONEVAL focuses on multi-step reasoning duties, assessing the standard of reasoning past final-answer accuracy. It evaluates every reasoning step for validity and redundancy, categorizing them into optimistic, impartial, or unfavourable labels. Step-level scores are computed primarily based on validity and redundancy after which aggregated to generate solution-level scores. The tactic makes use of varied LLMs with completely different base fashions, sizes, and coaching methods. Coaching information is sourced from PRM800K, a dataset of labeled step-by-step options collected by human annotators.
REASONEVAL achieves state-of-the-art efficiency on human-labeled datasets and might precisely detect completely different errors generated by perturbation. It reveals that enhanced final-answer accuracy doesn’t persistently enhance the standard of reasoning steps for advanced mathematical issues. The tactic’s evaluation additionally aids in information choice. Observations spotlight important decreases in validity scores for logical and calculation errors, whereas redundancy scores stay secure. REASONEVAL distinguishes between errors affecting validity and people introducing redundancy.
In conclusion, the analysis introduces REASONEVAL, an efficient metric for assessing reasoning step high quality primarily based on correctness and effectivity. Experimentation confirms its potential to establish numerous errors and aggressive efficiency in comparison with present strategies. REASONEVAL exposes inconsistencies between final-answer accuracy and reasoning step high quality whereas additionally proving efficient in information choice for coaching.
