CAR: Query-Guided Confidence-Aware Reranking for Retrieval-Augmented Generation
Researchers introduce CAR (Confidence-Aware Reranking), a training-free framework that improves document ranking in Retrieval-Augmented Generation systems by measuring how much each document increases the language model's confidence rather than just relevance. Testing across multiple datasets shows consistent improvements in ranking quality and downstream generation performance.
