What will I learn?
This Information Retrieval Course gives you a fast, practical path to building high-quality search. You will explore baseline keyword methods, TF-IDF, and BM25, then advance to semantic retrieval with embeddings, ANN, and scalable indexing. Learn to analyze datasets, model user intent, design test queries, label relevance, compare precision@5, and plan real improvements with monitoring, A/B tests, and learning-to-rank basics.
