English(EN) MMAgent-R$^2$: Learning to Rerank and Reject for Agentic mRAG

MMAgent-R^2 通过视觉重排和拒绝增强多模态检索 · 跟踪 2 个来源

研究人员推出 MMAgent-R$^2$,这是一个新颖的 Agentic 框架,旨在增强多模态检索增强生成 (mRAG) 系统。该框架解决了现有 mRAG 方法在知识库中处理视觉相似实体时存在的局限性,这些局限性会导致问答错误。MMAgent-R$^2$ 结合了视觉重排,通过比较查询和候选图像来精确识别目标实体,并结合主动拒绝机制,在必要时丢弃不可靠的结果或检索新候选。该系统通过具有复合奖励函数的 GRPO 训练进行优化,在 InfoSeek、E-VQA 和 MMhops 等基准测试中,尤其是在复杂的多跳推理任务中,展示了最先进的性能。 AI

影响 通过增强复杂知识库中的实体检索,提高视觉问答的准确性。
