Least squares I: Matrix problems Least squares approximation | Linear Algebra | Khan Academy
This is the first of 3 videos on least squares. In this one we show how to find a vector x that comes -closest- to solving Ax = b, and The goal of Alternating Least Squares is to find two matrices, U and P, such that their product is approximately equal to the original matrix of users and This video describes how the SVD can be used to solve linear systems of equations. In particular, it is possible to solve nonsquare
