Singular Value Decomposition: The Math Behind Netflix and AI

Singular Value Decomposition (SVD) is a mathematical technique that breaks down any matrix into three components: two rotations and a stretch. This method, originally developed by Eugenio Beltrami in 1873, is fundamental to many modern applications. It was famously used in a Netflix competition to predict movie ratings, demonstrating its power in filling in missing data within large, sparse matrices. AI
