证据感知检索在RAG中的下游效用评估
原标题：Assessing the Downstream Utility of Evidence-Aware Retrieval in RAG
AI 摘要
本研究评估了RAG中证据感知检索评估的下游效用，发现其虽能改变检索排名，但在训练、系统选择及答案质量预测上并不稳定。人类注释确认过滤保留了证据，但不同评估器对答案质量改善结论不一，凸显了评估信号有效性的组合问题。

Assessing the Downstream Utility of Evidence-Aware Retrieval in RAG Abstract. Retrieval evaluation for retrieval-augmented generation (RAG) is increasingly designed around whether retrieved passages contain evidence that can support generation, rather than topical relevance alone. We study whether this closer alignment with downstream evidence needs also makes retrieval evaluation more useful for the decisions built from it. Across five retrieval benchmarks and an end-to-end TREC RAG 2025 settin
