VerifiedProduction-grade RAG systems typically build and fully fuse three retrieval paths: vector retrieval, knowledge graphs, and keyword inverted indexes.78% similarVerifiedThe core process of Retrieval-Augmented Generation (RAG) consists of three steps: chunking and vectorizing knowledge base documents for storage, retrieving the most semantically relevant segments, and injecting those segments as context into the LLM prompt.77% similarUnverifiedAdvanced RAG variants such as HyDE, RAG-Fusion, and GraphRAG are upgrading RAG from simple semantic search to a knowledge question-answering system with deep reasoning capabilities.74% similarUnverified大模型二次开发的核心技术路径有两条：RAG通过向量数据库（如Faiss、Milvus、Chroma）注入私域知识无需修改权重，Fine-tuning用行业数据微调，常用LoRA、QLoRA等参数高效微调技术74% similarUnverifiedRetrieval-Augmented Generation (RAG) architecture decouples knowledge storage from language generation, evolving from simple vector similarity retrieval to hybrid retrieval combining BM25 and semantic vectors, iterative retrieval, and Graph RAG.74% similar
