English(EN) It Takes Two to Match: Co-Evolving Generative Retriever with Reinforcement Learning

新的检索框架CoGR使用LLM为搜索生成关键词

作者 PulseAugur 编辑部 · [2 个来源] · 2026-09-01 03:17

研究人员开发了CoGR，一个新颖的检索框架，它训练LLM为查询和项目生成检索表示。该方法使用两阶段训练过程，首先进行监督微调以对齐关键词空间，然后进行共同演进的强化学习。CoGR在应用市场和基准数据集上展示了卓越的性能，显著优于现有方法。 AI

影响该框架可以通过让LLM直接生成检索表示来提高搜索引擎的效率和相关性。
