Self-RAG model decides when to retrieve and self-critiques answers

Self-RAG is a novel approach to retrieval-augmented generation (RAG) that allows language models to decide when external information is necessary. Instead of retrieving documents for every query, Self-RAG uses "reflection tokens" to assess if retrieval is needed, grade the relevance of retrieved documents, and critique its own generated answers. This adaptive process helps prevent hallucinations by ensuring answers are supported by retrieved information and allows the model to loop and regenerate if the output is insufficient. AI

IMPACT Enhances RAG systems by enabling adaptive retrieval and self-critique, potentially reducing hallucinations and improving answer quality.
