About this course

Ever wondered how to make a large language model answer questions about your specific documents or recent information? Standard AI models have knowledge cutoffs and can't access your private data, often leading to generic or made-up answers. This course provides a clear, step-by-step introduction to Retrieval-Augmented Generation (RAG), the key technique for building smarter AI applications. You will learn how to connect LLMs to your own knowledge bases, enabling them to provide accurate, context-aware responses grounded in your data. What you'll learn: - Understand the core principles of RAG and how it complements large language models. - Learn to convert documents into vector embeddings for efficient semantic search. - Practice storing and retrieving information from a vector database. - Build a complete RAG pipeline in Python from the ground up. - Apply basic prompt engineering techniques to integrate retrieved context effectively. - Explore different strategies for splitting documents (chunking) for optimal performance. We'll start with the fundamental concepts of embeddings and vector search before guiding you through the practical steps of building a complete RAG system. You will work with written explanations and code examples to solidify your understanding. This course is designed for developers and tech enthusiasts new to AI. A basic familiarity with Python is helpful, but no prior experience with machine learning or LLMs is required. Start your journey into building practical, next-generation AI applications today.

Стало понятно, как привязать модель к своим данным и избежать выдумок, хотя примеров с реальными базами хотелось бы побольше.

নিজের ডকুমেন্ট থেকে মডেলকে সঠিক উত্তর দেওয়ানো এখন বুঝতে পারছি, আর হ্যালুসিনেশন অনেক কমে গেছে। ভেক্টর সার্চের অংশটা আরেকটু বিস্তারিত হলে ভালো হতো, তবে সব মিলিয়ে দারুণ একটা শুরু।
