Enterprise RAG (Retrieval-Augmented Generation) Frameworks

About this course

“This course contains the use of artificial intelligence.”

Large language models inherently struggle with frozen parametric knowledge, causing enterprise-critical data staleness and hallucination. Scaling generative AI safely and accurately requires more than prompt engineering; it demands a highly governed, cost-efficient retrieval architecture. This course provides a definitive engineering blueprint for designing, deploying, and operating Retrieval-Augmented Generation (RAG) systems in strict production environments.

Course Overview and Architectural Scope

This curriculum dissects the end-to-end RAG architecture, explicitly separating the offline indexing pipeline from the online query execution path. Participants will learn how to parse heterogeneous enterprise documents, implement semantic and structure-aware chunking, and utilize vector databases for scalable approximate nearest neighbor (ANN) search. The program details advanced retrieval mechanics, demonstrating how to fuse dense semantic embeddings with sparse lexical search and optimize results using cross-encoder reranking to maximize context precision. What is Hybrid Retrieval in RAG?

Hybrid retrieval combines dense semantic vector search with sparse lexical search, such as BM25, and merges the results using Reciprocal Rank Fusion. This approach ensures high recall for both broad conceptual queries and exact alphanumeric keyword matches, significantly improving overall context relevance for the language model.

How does Agentic RAG differ from standard RAG?

Standard RAG uses a fixed, linear pipeline for embedding, retrieval, and generation. Agentic RAG introduces an iterative reasoning loop where a language model autonomously routes queries, selects tools, evaluates retrieved context, and decides if multiple retrieval steps are necessary before synthesizing a final answer.
