English(EN) Prompt-Based Abstention Fails Under Misleading Context: A Controlled Study of Small Frozen RAG Models

新基准揭示RAG模型在误导性上下文方面存在困难

arXiv上发表的一项新研究引入了GRAB-RAG,这是一个旨在评估检索增强生成(RAG)模型区分缺失上下文和误导性上下文能力的基准。研究发现,即使有明确的弃权提示,小型冻结RAG模型在包含故意植入的误导性信息的问答中,错误率也超过40%。冲突检查和自然语言推理(NLI)验证器在减少错误答案方面有所改进,但它们要么牺牲了正确答案的覆盖率,要么在模型参数记忆与误导性段落一致时失效。 AI

影响 凸显了RAG系统中关键的安全漏洞,需要改进上下文验证机制以实现可靠的AI部署。

    基于提示的弃权在误导性上下文下失效:小型冻结RAG模型受控研究

    Missing and misleading evidence are not the same problem in retrieval-augmented generation (RAG), but prompt-based abstention treats them alike. Models abstain when context is absent, not when it is misleading. We introduce GRAB-RAG (Graded Abstention Benchmark for Retrieval-Augm…
