Build memory systems for AI agents with in-context history, vector stores for semantic search, episodic memories of past interactions, and fact-based semantic knowledge.
Build robust document ingestion pipelines: extract text, chunk, deduplicate, embed, and monitor health at scale.
Ground LLM responses in facts using RAG, self-consistency sampling, and faithful feedback loops to reduce hallucinations and build user trust.
Build research agents that search the web, score source credibility, deduplicate results, follow up on findings, and generate well-cited reports.
Build GraphRAG systems: extract entities and relationships, design graph schemas, detect communities, and combine vector and graph retrieval.
Master multimodal embeddings: CLIP for text-image, ImageBind for audio/3D, cross-modal search, and production storage strategies.
Learn how agentic RAG systems use reasoning and iterative retrieval to outperform static RAG pipelines, including CRAG, FLARE, and self-ask decomposition patterns.
Explore naive RAG limitations and advanced architectures like modular RAG, self-RAG, and corrective RAG that enable production-grade question-answering systems.
Explore chunking strategies from fixed-size to semantic splitting, including sentence-window retrieval and late chunking techniques that dramatically improve retrieval quality.
Master semantic chunking, recursive splitting, parent-child strategies, and late chunking to maximize RAG retrieval quality and cut retrieval latency.
Implement citation grounding to force LLMs to cite sources, validate claims against context, and detect hallucinations through automatic faithfulness scoring.
Build feedback loops: log retrieval signals, identify failures, A/B test changes, and automatically improve your RAG pipeline from production data.
Master the RAGAS framework and build evaluation pipelines that measure faithfulness, context relevance, and answer quality without expensive human annotation.
Explore why dense embeddings alone fail, and how hybrid search combining vector similarity with BM25 sparse retrieval dramatically improves RAG quality.
Build GraphRAG systems using knowledge graph traversal and vector search together to handle complex multi-hop questions and relationship-aware context retrieval.
Choose between long-context LLMs and RAG by understanding the lost-in-the-middle problem, cost dynamics, and latency tradeoffs.
Master metadata filtering in RAG systems: design schemas, implement self-querying, combine filters with vector similarity, and isolate tenants securely.
Build RAG systems that handle PDFs, tables, images, and charts by combining text extraction, table embeddings, and vision encoders for unified multimodal search.
Build production-ready RAG systems with semantic chunking, embedding optimization, reranking, citation tracking, and hallucination detection.
Build comprehensive monitoring for RAG systems tracking retrieval quality, generation speed, user feedback, and cost metrics to detect quality drift in production.
Transform user queries to improve retrieval with rewriting, HyDE, step-back prompting, and multi-hop decomposition techniques that boost RAG accuracy.
Understand why vector similarity ranks poorly, how cross-encoder rerankers fix it, and implement production-grade reranking with latency optimization.
Master pre-filtering, HNSW payload filtering, pgvector filtering, hybrid scoring, and re-ranking to build fast, accurate semantic search at scale.
