About this course

Modern AI applications require more than just a pre-trained model; they need the ability to access and utilize specific, real-world data. This course introduces you to Retrieval-Augmented Generation (RAG), a powerful technique that bridges the gap between static models and dynamic information. You will progress from understanding basic terminology to constructing a functional pipeline that connects a language model to a searchable knowledge base. By reading through detailed explanations and reviewing code implementations, you will learn to design systems that provide precise answers based on your own datasets. What you'll learn: - Understand the foundational concepts of RAG and its role in modern AI. - Configure vector databases for efficient similarity searches and data storage. - Apply prompt engineering strategies to optimize retrieval results and model output. - Build a basic RAG pipeline to process and query custom documents through written exercises. - Practice evaluating the accuracy and relevance of generated responses using modern metrics. - Explore retrieval-augmented generation patterns for various industry use cases. The course begins with core definitions and architectural basics before guiding you through the logic of data ingestion, embedding, and retrieval. It is designed specifically for beginners with no prior experience in AI engineering or vector search. Start your journey into building data-aware AI applications today.
