DeepSeek RAG Retrieval-Augmented Tutorial
Complete tutorial for building a RAG system based on DeepSeek: document loading, text splitting, vector retrieval, re-ranking, and multi-turn dialogue integration. Includes LangChain and LlamaIndex practical code and enterprise-level RAG architecture design.
阅读教程 →RAG Re-ranking and Hybrid Search in Practice: From BM25 to Cross-Encoder
Vector retrieval alone has limited recall; reranking is a key step in improving RAG effectiveness. This article systematically explains BM25 sparse retrieval, vector retrieval with RRF fusion, and complete practices for Cross-Encoder reranking.
阅读教程 →Vector Database Selection in Practice
Vector databases are the core infrastructure of RAG systems, but with many options like Milvus, Pinecone, Weaviate, Qdrant, and Chroma, how do you make the optimal selection decision? This article comprehensively compares performance, cost, ease of use, and scalability, and provides selection recommendations based on real business scenarios.
阅读教程 →Deep Optimization of Document Chunking Strategies
Document chunking is the most underestimated critical step in RAG systems. The quality of the chunking strategy directly affects retrieval quality and the accuracy of the final answer. This article deeply analyzes strategies such as fixed-size chunking, semantic chunking, recursive chunking, and sentence-level chunking to help you find the optimal solution.
阅读教程 →Design of Multilingual RAG Systems
Building a RAG system that supports multiple languages such as Chinese, English, Japanese, and Korean presents unique challenges. This article explains a complete solution for multilingual embeddings, cross-lingual retrieval, translation strategies, and performance optimization.
阅读教程 →RAG Caching and Performance Optimization
The performance bottleneck of a RAG system is often not the model but the retrieval. This article explains multi-level caching strategies, Redis acceleration, semantic caching, and batch optimization techniques to increase your RAG system's response speed by 10 times.
阅读教程 →Large Model Hallucination: Root Cause Analysis and Mitigation Strategies
Hallucination is one of the most troublesome problems in large model applications. This article provides an in-depth analysis of the causes of hallucination and offers systematic mitigation strategies such as RAG, fact-checking, and uncertainty quantification to help build more reliable AI applications.
阅读教程 →Vector Database Selection: Chroma vs Pinecone vs Milvus
Vector databases are core components of RAG systems. This article compares three mainstream vector databases—Chroma, Pinecone, and Milvus—from four dimensions: performance, ease of use, cost, and scalability, helping you make the right selection decision.
