Advancing Small Language Models as Efficient Reasoners

摘要

Complex reasoning tasks, such as mathematical reasoning, coding, and planning, present significant challenges for language models, particularly small, open models. In this talk, I will cover our recent research on advancing open, small language models as efficient reasoners for complex tasks. First, I will introduce DART-Math, a new data synthesis method and accompanied datasets for mathematical reasoning, achieving state-of-the-art COT reasoning performance. Then, I will present B-STaR, our innovative self-improving algorithm that monitors training dynamics and balances exploration and exploitation to achieve scalable improvements for self-taught reasoners. I will also discuss our research on non-myopic generation, which enhances the performance of language models across various complex reasoning scenarios at decoding time. Lastly, I will present our exaimination for the "math for AI" vision, studying whether learning mathematical problem-solving, a highly popular task recently, can help LLMs learn general reasoning or not.
