What will I learn?
This Information Retrieval Course provides a quick, practical route to developing high-quality search. You will investigate baseline keyword techniques, TF-IDF, and BM25, then progress to semantic retrieval using embeddings, ANN, and scalable indexing. Learn to examine datasets, model user intent, create test queries, label relevance, compare precision@5, and plan actual enhancements with monitoring, A/B tests, and basics of learning-to-rank.
