This article explains the various metrics used to evaluate Retrieval-Augmented Generation (RAG) systems, categorizing them into retrieval, generation, and operational metrics. Retrieval metrics like Hit Rate, Recall@k, MRR, and nDCG@k assess the system's ability to find relevant document chunks. Generation metrics focus on how well the Large Language Model utilizes these chunks for a faithful and relevant answer. Finally, operational metrics consider cost, latency, and storage requirements for practical deployment. AI
