A Model Can Help Itself: Reward-Free Self-Training for LLM Reasoning

Mengqi Li, Lei Zhao, Anthony Man-Cho So +2

Can language models improve their reasoning performance without external rewards, using only their own sampled responses for training? We show that they can. We propose Self-evolvi…

Bridging Formal Language with Chain-of-Thought Reasoning to Geometry Problem Solving

Tianyun Yang, Yunwen Li, Ziniu Li +3

Large vision language models exhibit notable limitations on Geometry Problem Solving (GPS) because of their unreliable diagram interpretation and pure natural-language reasoning. A…
