information Retrieval Course
This course covers foundational and advanced techniques in information retrieval, from keyword-based methods like TF-IDF and BM25 to semantic search using embeddings and approximate nearest neighbors. Participants will learn to analyze datasets, model user intent, evaluate search performance with metrics like precision@5, and implement improvements through A/B testing and learning-to-rank principles.

What will I learn?
This Information Retrieval Course provides a swift, 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 analyse datasets, model user intent, design test queries, label relevance, compare precision@5, and plan genuine improvements with monitoring, A/B tests, and learning-to-rank fundamentals.

Your lessons are perfect. I purchased 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...
