What You Will Learn

Architect end-to-end Retrieval-Augmented Generation (RAG) pipelines bridging private knowledge stores with foundation models.
Ingest, parse, and clean unstructured multi-modal documents (PDFs, Markdown, HTML, tables) while preserving semantic hierarchy.
Implement optimal chunking strategies including recursive character splitting, sliding windows, and Parent-Document retrieval.
Generate and evaluate dense, sparse, and multi-vector embeddings using cosine similarity and dot product metrics.
Deploy and configure production vector databases (pgvector, Chroma, Qdrant) using HNSW and IVF approximate nearest neighbor indexes.
Build hybrid retrieval engines combining BM25 keyword search with dense vector similarity via Reciprocal Rank Fusion (RRF).
Formulate intelligent query transformations including HyDE (Hypothetical Document Embeddings) and sub-query routing.
Apply cross-encoder reranking models to filter low-relevance passages and maximize precision@k.
Construct defensive context windows with bracketed source citations and strict refusal mechanics when evidence is insufficient.
Evaluate RAG accuracy and eliminate hallucinations using automated benchmarks measuring Faithfulness and Context Precision.
Enforce strict server-side tenant isolation, document ACL checks, and guardrails against indirect prompt injection in retrieved data.
Build 7 production portfolio projects and pass the Module 14 Capstone Challenge evaluated by the RAG & Knowledge Systems Mastery Agent.
