Measuring the Performance of VectorRAG vs GraphRAG

Session Track: AI

Session Time:

Session description

Join this session for an in-depth exploration of evaluating Retrieval Augmented Generation (RAG) pipelines, which are crucial for enhancing the performance of large language models (LLMs). As RAG becomes increasingly prevalent, understanding its evaluation is vital to identifying and improving weak points. This session delves into the benefits of integrating knowledge graphs for better grounding and explainability, contrasting it with traditional vector-based retrievers. We will discuss the latest LLM-based tools for automated RAG evaluation, and showcase applications using Neo4j-backed RAG pipelines and the RAG Automated Assessment (RAGAS) framework. You will gain valuable insights into advanced RAG evaluation techniques, helping you optimise your own RAG implementations.
