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

Cliff策略通过奖励第一个正确步骤来改进LLM推理

作者 PulseAugur 编辑部 · [1 个来源] · 2026-09-02 17:03

研究人员引入了Cliff，一种用于大型语言模型中具有可验证奖励（RLVR）的强化学习的新型奖励塑造策略。Cliff通过关注中间推理过程，解决了现有方法依赖粗略结果奖励的局限性。该策略识别模型推理过程中的第一个错误，并利用此信号提供token级别的优势，奖励正确的词缀并惩罚后续的错误。实验表明，与标准方法（如on-policy distillation和GRPO）相比，Cliff显著提高了推理性能。 AI

影响该方法有望提高LLM推理能力的鲁棒性和可靠性，尤其是在需要循序渐进逻辑的复杂任务中。

Cliff：学习过程从第一次错误中获得奖励

Reinforcement learning with verifiable rewards (RLVR) has emerged as a powerful paradigm for large language model (LLM) post-training, but its reliance on coarse outcome rewards leads to limited guidance on intermediate reasoning processes. Existing approaches such as process rew…
