Português(PT) RAG na Prática: Como Avaliar Retrieval Sem Virar "Achei Que Ficou Bom"

评估 RAG 系统:指标和分层工具

本文讨论了评估检索增强生成 (RAG) 系统的实用方法,超越了主观评估。它强调了通过使用 Precision@k、Recall@k、MRR 和 nDCG 等特定指标来区分检索失败和生成失败的重要性。作者提出了一个分层评估工具,其中包括确定性检查和 LLM 作为裁判的方法,以确保对 RAG 性能进行稳健且可重现的评估。 AI

影响 为提高 RAG 系统的可靠性和准确性提供了框架,这对于企业级 AI 应用至关重要。
