Retrieval-augmented generation (RAG) is a powerful paradigm that combines the strengths of information retrieval and generative AI models to produce accurate, context-relevant results. This method improves the efficiency of generative models by integrating external knowledge sources for various applications. This beginner RAG course introduces learners to the fundamental concepts of RAG, offering a comprehensive understanding of its architecture and applications. You’ll learn how to implement RAG pipelines using LangChain, gaining hands-on experience building your first RAG solution. Additionally, you’ll create a complete frontend application using Streamlit, simplifying user interaction with your project. After completing this course, you’ll have the skills to apply RAG principles and techniques to build practical RAG solutions using LangChain and Streamlit, setting a strong foundation for more advanced concepts.
