ReDeEP: Detecting Hallucination in Retrieval-Augmented Generation via Mechanistic Interpretability

ICLR 2025spotlight

Retrieval-Augmented Generation (RAG) models are designed to incorporate external knowledge, reducing hallucinations caused by insufficient parametric (internal) knowledge. However, even with accurate and relevant retrieved content, RAG models can still produce hallucinations by generating outputs th…
