What will I learn?
This Information Retrieval Course provides a quick, hands-on way to create top-notch search systems. You'll start with basic keyword techniques, 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 evaluation queries, assess relevance, measure precision@5, and implement real enhancements through monitoring, A/B testing, and introductory learning-to-rank methods.
