information Retrieval Course
This course teaches practical information retrieval techniques, from basic keyword search and ranking models like TF-IDF and BM25 to advanced semantic search using embeddings and efficient indexing. Learners will gain skills in data analysis, user intent modeling, and search evaluation through metrics like precision@5, A/B testing, and learning-to-rank methods to build effective search systems.

What will I learn?
This Information Retrieval Course provides a quick and practical way to build good search systems. You will learn basic keyword approaches, TF-IDF, and BM25, then move to advanced semantic search using embeddings, ANN, and efficient indexing. You will also learn to examine datasets, understand what users want, create test searches, mark relevant results, measure precision at 5, and make real improvements using monitoring, A/B testing, and basic learning-to-rank methods.
Elevify advantages
