Your Retriever Already Knows: Distribution-Shape QPP for RAG Retrieval Sufficiency

Matyáš Veselý, Michal Průšek, Jiří Franc

Standard Retrieval-Augmented Generation (RAG) pipelines often provide no reliable inference-time signal of whether retrieval succeeded; on ambiguous or out-of-scope queries, genera…
