This video by Mitesh Patel from NVIDIA introduces HybridRAG, a system fusing knowledge graphs and vector retrieval for enhanced RAG capabilities. It details the architecture, creation process (including LLM-driven triplet extraction and prompt engineering), and optimization strategies for graph-based RAG systems. The presentation also covers performance evaluation using tools like Ragas and discusses factors for deciding between graph, semantic, or hybrid RAG approaches based on data and use case.
