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 semantic search using embeddings, approximate nearest neighbours, and efficient indexing. You'll learn to examine datasets, understand user needs, create evaluation queries, assess relevance, measure precision at 5, and implement improvements through monitoring, A/B testing, and introductory learning-to-rank methods.
