Systems using ML to suggest relevant items (content, products, connections) based on user behavior and item features. Also called recommender system.
Overview
Modern recommendation systems combine: collaborative filtering (user-item interaction matrix), content-based filtering (item embeddings), and LLM-powered explanation/reranking. LLMs improve: cold-start (describe new items), explanation quality, and conversational refinement of recommendations. Used in streaming, e-commerce, and professional networks.
