Practical overview
When it fits
Use it when you want a staged learning route through RAG or need a reference topic for a particular pipeline question, such as retrieval selection, answer generation or vector-database architecture.
Who it is for
- Learners developing large-language-model applications
- Developers working through RAG implementation questions
- Engineers studying knowledge-base and vector-database systems
- Researchers interested in RAG methods
Documented uses
- Study document cleaning and preprocessing, including image and table handling.
- Compare vector, keyword, graph and hybrid retrieval approaches.
- Learn how retrieved content can be used to generate structured answers with citations.
- Explore GraphRAG, RAG agents, adaptive retrieval and multimodal retrieval.
- Understand Milvus vector-database architecture and production-oriented patterns.
Requirements & limits
The repository is public and MIT-licensed. Its README specifies Python 3.10+ and LangChain 0.1.0+ for the tutorial setup.
- The repository is a learning map, not a single ready-to-use RAG application.
- Jupyter notebooks are central to its hands-on material.
- Some listed notebooks and topics are marked as under development, including evaluation and several implementation exercises.
- The material spans basic retrieval as well as GraphRAG, Milvus architecture, agents and multimodal directions.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
Follow the RAG learning path from foundations through answer generation
Study the repository’s staged concepts and notebooks for data preparation, retrieval, and RAG answer generation.
Before you start
- Access to the public RAG-LEARN repository.
- Jupyter Notebook environment for the notebook-based practice; the repository lists Python 3.10+ and LangChain 0.1.0+.
Steps
Read the foundational RAG document at docs/Readme.md.
Work through 01_data_clean/data_process.ipynb for data cleaning and preprocessing.
Study retrieval approaches in 02_data_retriever/data_retriever.ipynb and consult embedding_models.md for model-selection guidance.
Continue to 03_llm_answer/llm_answer.ipynb for prompt optimization and answer generation from retrieved content.
Expected outcome
A guided progression through RAG foundations, data preparation, retrieval methods, and answer generation.
Guide limitations
- The repository is described as a learning map, not a single demo application.
- Some listed notebooks and advanced topics are marked as under development; this path does not document a complete production deployment.
