Description
“RAG with Local LLMs: Ollama, LangChain & ChromaDB” is a course on Retrieval-Augmented Generation (RAG) applications using Large Language Models, published by the online academy Udemy. You will learn how RAG systems combine document retrieval with language generation to produce more relevant, context-aware responses based on your own data. The course introduces Ollama for running local language models, LangChain for orchestrating retrieval and generation workflows, and ChromaDB for storing and searching vector embeddings. You will thoroughly explore key concepts such as document loading, text splitting, embedding generation, vector databases, semantic search, retrieval pipelines, and prompt engineering. Through hands-on, step-by-step implementation, you will discover how to connect your documents to an AI model, retrieve relevant information, and generate accurate, context-based responses.
You will also gain a deeper understanding of how local AI solutions can enhance privacy, customization, and control over your applications. Whether you are a Python developer, an AI enthusiast, or an aspiring machine learning engineer, this course provides a solid, practical foundation for building RAG applications using local language models and open-source tools. Throughout the course, you will explore advanced techniques—such as evaluating retrieval quality, comparing various search methods (including BM25 and re-ranking), and building an interactive document-based Q&A application. This will provide a deeper understanding of the practical applications of these technologies and prepare you to develop real-world, professional projects in this field. The course offers a clear progression from fundamental concepts to the implementation of a complete RAG (Retrieval-Augmented Generation) system.
