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 techniques, TF-IDF, and BM25, then move on to advanced 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 improvements through monitoring, A/B testing, and introductory learning-to-rank methods.

Your classes are perfect. I got the one-year package and finally have the chance to follow several topics I'm interested in without having to switch platforms... thank you for everything you do, I've already recommended you to others...
