Safe: Enhancing Mathematical Reasoning in Large Language Models via Retrospective Step-aware Formal Verification

Chengwu Liu, Ye Yuan, Yichun Yin +7

Chain-of-Thought (CoT) prompting has become the de facto method to elicit reasoning capabilities from large language models (LLMs). However, to mitigate hallucinations in CoT that…

Teaching LLMs According to Their Aptitude: Adaptive Reasoning for Mathematical Problem Solving

Xin Xu, Yan Xu, Tianhao Chen +9

Existing approaches to mathematical reasoning with large language models (LLMs) rely on Chain-of-Thought (CoT) for generalizability or Tool-Integrated Reasoning (TIR) for precise c…
