English(EN) Mitigating Over-Optimization in PRM-Guided Search in Mathematical Reasoning by Optimizing the Guide

新方法缓解 AI 数学推理中的过度优化问题

研究人员开发了一种名为 maximin PRM 引导搜索的新方法,以解决数学推理中的过度优化问题。该方法解决了过程奖励模型 (PRM) 可能为不正确的局部解分配过高分数的问题,导致搜索算法放弃有效的推理路径。通过将搜索构建为一个考虑了合理奖励扰动的鲁棒优化问题,maximin PRM 引导搜索降低了对这些嘈杂的 PRM 异常值的敏感性。这种无需训练的方法在各种设置下持续将 PRM 引导搜索的性能提高 17-35%,而无需进行微调或在线适应。 AI

影响 引入了一种新技术,以提高 AI 系统在复杂数学推理任务中的可靠性和性能。

    通过优化引导器缓解 PRM 引导搜索中的过度优化问题

    arXiv:2608.30051v1 Announce Type: new Abstract: Process reward models (PRMs) provide dense step-level guidance for search-based reasoning, enabling inference-time compute to be allocated toward promising partial solutions. However, recent evidence suggests that PRM-guided search …
