新的RAG防御在准入时控制向量中心性

研究人员开发了一种新的方法来控制检索增强生成(RAG)系统中的向量中心性,解决了注入文档影响不相关查询的风险。提出的解决方案涉及一个准入时门控,该门控根据哨兵查询对候选文档进行评分,在将潜在的中心性文档插入系统之前将其隔离。这种方法旨在通过早期识别和隔离有问题文档来减轻投毒攻击,从而提高RAG系统的安全性和可靠性。 AI

影响 增强了检索增强生成系统免受投毒攻击的安全性和可靠性。

    当全局门控足够时:各向异性向量检索系统中的准入时中心性控制

    Vector hubness, where a few points become nearest neighbors of many queries, creates a poisoning risk in retrieval-augmented generation (RAG): one injected document can influence unrelated requests. Existing defenses use periodic reverse-kNN scans, leaving an exposure window and …
