What will I learn?
This Information Retrieval Course provides a quick, hands-on way to create effective search systems. You'll start with basic keyword approaches, TF-IDF, and BM25, then move on to semantic search using embeddings, ANN, and efficient indexing. You'll learn to examine datasets, understand user needs, create test searches, assess relevance, measure precision@5, and make real enhancements through monitoring, A/B testing, and introductory learning-to-rank techniques.
