UnverifiedRAG evaluation should cover four dimensions: the retrieval layer (Recall@k, Precision@k, MRR, nDCG), the generation layer (faithfulness, answer relevance, answer correctness), context utilization (context precision and recall), and the system layer (latency p50/p95, cost per query, abstention rate).71% similarUnverifiedA typical RAG system pipeline consists of four stages—document chunking, vector embedding, similarity retrieval, and context concatenation—each of which can become a potential injection point for malicious instructions.71% similarUnverifiedRAG系统的行为由基础语言模型、向量数据库中的知识文档、检索策略和提示词模板三个变量共同决定68% similarUnverifiedThe pre-parsing layer approach of using specialized tools to segment documents into structured chunks with coordinates before feeding them to an LLM is known as chunk-level RAG architecture, and is one of the mainstream engineering practices for balancing accuracy, cost, and speed.68% similar
