What will I learn?
This Information Retrieval Course provides a quick, hands-on way to create effective search systems. You will study basic keyword approaches, TF-IDF, and BM25, then move on to meaning-based retrieval using embeddings, ANN, and efficient indexing. Learn to examine datasets, understand user needs, create evaluation queries, assess relevance, measure precision@5, and implement real enhancements through tracking, A/B testing, and introductory learning-to-rank techniques.
