English(EN) Cliff: Learning Process Rewards from the First Mistake

Cliff 方法通过奖励正确的前缀来改进 LLM 推理

研究人员推出了一种名为 Cliff 的新颖奖励塑造策略,用于大型语言模型中的可验证奖励强化学习 (RLVR)。Cliff 利用现成的语言模型来精确定位推理过程中的第一个错误,从而将生成过程划分为一个正确的前缀和一个不正确的后缀。这种方法将信号转换为 token 级优势,提供了比传统基于结果的奖励更精细化的反馈。实验表明,Cliff 显著提高了推理性能,优于现有的方法,如 On-Policy DistillationGRPOAI

影响 该方法通过在训练过程中提供更精细化的反馈,有望提高 LLM 推理的鲁棒性和准确性。

    Cliff:学习过程从第一次错误中获得奖励

    Cliff improves reinforcement learning with verifiable rewards by using an off-the-shelf language model to detect the first reasoning error and shaping token-level advantages accordingly.
