RAG pipelines evaluated with RAGAS, hybrid search, and cross-encoder reranking

By PulseAugur Editorial · [2 sources] ·

This guide details methods for evaluating Retrieval-Augmented Generation (RAG) pipelines, focusing on retrieval quality and latency. It introduces the RAGAS metric suite for assessing faithfulness, context precision, and answer relevance, and demonstrates a hybrid search architecture combining BM25 and dense retrieval. The approach uses a cross-encoder for reranking, aiming to achieve low latency within service level objectives. AI

IMPACT Improves RAG system evaluation and hybrid retrieval techniques, potentially leading to more accurate and efficient information retrieval in LLM applications.

RANK_REASON The cluster details technical methods and evaluations for RAG pipelines, including specific metrics and architectures, which falls under research and development in AI.
