RAG pipeline evaluation: Metrics and test harness for accuracy

Evaluating Retrieval-Augmented Generation (RAG) pipelines requires a systematic approach beyond basic testing to ensure accurate and relevant responses. Failures can occur in either the retrieval component, which may surface irrelevant information, or the generation component, which might ignore context and hallucinate. To address this, developers need to implement specific metrics such as context recall to assess retrieval effectiveness and faithfulness to verify that generated answers are solely based on the provided context. Building custom data structures and utilizing language models as judges are key strategies for developing a robust test harness to catch these issues before deployment. AI
