Cheems: A Practical Guidance for Building and Evaluating Chinese Reward Models from Scratch

Xueru Wen, Jie Lou, Zichao Li +9

Reward models (RMs) are crucial for aligning large language models (LLMs) with human preferences. However, most RM research is centered on English and relies heavily on synthetic r…
