Master RAG: Ultimate Retrieval-Augmented Generation Course

Sandra Sorel develops RAG through the preparation and retrieval choices that determine the context supplied to a model. Query transformation and pre- or post-retrieval optimization connect with a LangGraph application project. It suits learners seeking a technical treatment who want to diagnose a retrieval problem before adding another component to the pipeline.

What you will learn

• Prepare varied documents and compare chunking methods.
• Explore query transformation and retrieval optimization.
• Follow a LangGraph-based application project.

Who this suits

Developers exploring RAG implementation; inspect the published skills, project requirements and expected programming experience before enrolling.

Before you enroll

Model APIs, vector databases and hosting may cost extra. Verify package versions before reproducing demonstrations. Use fictional or permissioned documents and test access controls. Evaluate retrieval quality separately from answer quality, include questions the documents cannot answer and check citations. A working demonstration does not establish factual accuracy, resistance to malicious documents or production reliability.

Udemy offers paid purchase or subscription access depending on the current course and region. Paid teaching courses provide completion certificates under Udemy’s policy. Check current access terms and any separate software or material costs before enrolling.

Put it into practice

Choose one retrieval failure and compare an indexing change with a query transformation, documenting which intervention addresses the actual cause.
