Lecture 5 Least-squares - Stanford Engineering Everywhere

Least-squares (approximate) solution • assume A is full rank, skinny • to find xls, we’ll minimize norm of residual squared, krk2 = xTATAx−2yTAx+yTy • set gradient w.r.t. x to zero: ∇xkrk2 = 2ATAx−2ATy = 0 • yields the normal equations: ATAx = ATy • assumptions imply ATA invertible, so we have xls = (ATA)−1ATy. . . a very famous formula
