Chapter 11 Least Squares, Pseudo-Inverses, PCA &SVD

Least Squares, Pseudo-Inverses, PCA &SVD 11.1 Least Squares Problems and Pseudo-Inverses The method of least squares is a way of “solving” an overdetermined system of linear equations Ax = b, i.e., a system in which A is a rectangular m × n-matrix with more equations than unknowns (when m>n).

Lecture 33: Left and right inverses; pseudoinverse

Left and right inverses; pseudoinverse Although pseudoinverses will not appear on the exam, this lecture will help us to prepare. Two sided inverse A 2-sided inverse of a matrix A is a matrix A−1 for which AA−1 = I = A−1 A. This is what we’ve called the inverse of A. Here r = n = m; the matrix A has full rank. Left inverse

Matrix inverses - Harvey Mudd College

Matrix inverses Recall... De nition A square matrix A is invertible (or nonsingular) if 9matrix B such that AB = I and BA = I. (We say B is an inverse of A.) Remark Not all square matrices are invertible. Theorem. If A is invertible, then its inverse is unique. Remark When A is invertible, we denote its inverse as A 1. Theorem.
