Matrix Factorization and Embeddings

The technique that defined the modern era of recommendation is deceptively simple: represent every user and every item as a short list of numbers — a vector of latent factors — such that a user's affinity for an item is just the dot product of their vectors. Matrix factorization turned recommendation into learning good embeddings, and it's the conceptual bridge from classical collaborative filtering to today's deep-learning systems.

Represent every user and item as a short vector of latent factors, and a user's affinity for an item becomes just the dot product of their vectors. Matrix factorization turned recommendation into learning good embeddings — the technique that won the Netflix Prize and the conceptual bridge from classical collaborative filtering to today's deep-learning systems and vector search.
