Master RAG: Retrieval-Augmented Generation Systems [NEW]

Paulo Dichone develops RAG through its retrieval and generation components, then explores approaches such as sparse or dense search and reranking. It suits learners who want to connect individual techniques with a complete document-based workflow. The important comparison is whether a change retrieves more useful evidence, rather than whether the final answer sounds more confident.

What you will learn

• Understand retrieval and generation components.
• Compare sparse and dense search approaches.
• Explore query expansion and reranking.

Who this suits

Learners studying technical RAG applications; preview the programming, package and API requirements 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

Compare a direct query with an expanded query on a small fictional corpus and explain which additional passages are useful and which introduce distracting context.
