VerifiedRAG（检索增强生成）技术架构将文档切片、向量化、存入向量数据库，查询时先检索相关片段再交给模型生成回答85% similarVerifiedRAG addresses the limitation of large models' knowledge cutoff dates by splitting private documents into text chunks, converting them into vector representations stored in a vector database, and injecting retrieved relevant content into the Prompt.85% similarUnverifiedRAG mitigates AI hallucination by splitting code into semantic chunks, converting them into high-dimensional vectors via a vector embedding model for storage in a vector database, and injecting the retrieved results into the LLM prompt.84% similarVerifiedThe core logic of RAG is to slice documents and store them as vectors, then retrieve relevant fragments through semantic similarity at query time and inject them into the context.82% similar
