About this course

Navigating large codebases and extensive technical documentation can be time-consuming. Retrieval-Augmented Generation (RAG) offers a powerful solution by allowing you to query your repositories and extract precise, context-aware answers. This course guides you through the foundational concepts of building RAG systems tailored for technical environments. By reading through practical Python examples and clear explanations, you will learn how to process source code, generate embeddings, and leverage vector databases to retrieve relevant context for language models. What you will learn: - Understand the fundamental architecture and terminology of Retrieval-Augmented Generation. - Process and chunk code files and markdown documentation for optimal embedding. - Configure vector databases to store and execute semantic searches on technical content. - Apply basic prompt engineering techniques to improve context retrieval and response accuracy. - Build a text-based query pipeline connecting Python scripts, search retrievers, and language models. - Practice retrieving relevant code snippets through structured written exercises. The curriculum begins with essential AI terminology and foundational definitions before moving into practical implementation. You will follow a logical progression from basic data ingestion to constructing a complete semantic search workflow. Designed for beginners and developers with basic Python knowledge, this course requires no prior machine learning experience. Start building intelligent search tools for your technical projects today.

Sempre perdia tempo demais procurando trechos especรญficos na nossa documentaรงรฃo tรฉcnica, entรฃo este curso caiu como uma luva. Ele mostra com clareza como montar uma busca semรขntica que entende a intenรงรฃo da pergunta, indexando o repositรณrio e usando um banco vetorial. Os exemplos em Python sรฃo diretos e consegui reproduzir cada passo sem travar. Gostei especialmente da parte que explica como dividir o cรณdigo em pedaรงos รบteis antes de indexar. Montei meu prรณprio sistema sobre o nosso repositรณrio e a diferenรงa na produtividade foi enorme. Recomendo muito para quem lida com bases de cรณdigo grandes.

J'avais une grosse base de code mal documentรฉe et chercher la moindre fonction tournait au cauchemar. Ce cours m'a appris ร  construire une recherche sรฉmantique qui comprend vraiment le sens des requรชtes, pas juste les mots-clรฉs. La partie sur l'indexation du dรฉpรดt et le passage par une base vectorielle est expliquรฉe pas ร  pas, sans rien survoler. J'ai suivi les exemples en Python et montรฉ mon propre systรจme de recherche sur ma doc technique en une soirรฉe. Le rรฉsultat est bluffant : je retrouve enfin le bon bout de code instantanรฉment. Indispensable pour quiconque gรจre un projet un peu volumineux.
