Retrieval-Augmented Generation (RAG) systems must ensure that retrieved information is effectively used in generated responses to avoid hallucinations, incomplete outputs, and retrieval inefficiencies. To optimize RAG evaluations, techniques such as Precision@k and Recall@k, Chunk Attribution, Fine-tuning generation models, Context Adherence, BLEU & ROUGE scores, and Chunk Utilization can be employed. These methods help refine embeddings, re-ranking strategies, chunking strategies, fine-tune generation models, reinforce retrieval dependency, and measure context adherence to improve response quality and accuracy. By leveraging these techniques and tools like Galileo, teams can build enterprise-grade RAG systems that deliver reliable AI performance.
