CS229 Lecture notes - Stanford Engineering Everywhere
CS229 Winter 2003 2 To establish notation for future use, we’ll use x(i) to denote the “input” variables (living area in this example), also called input features, and y(i) to denote the “output” or target variable that we are trying to predict

Locally-weighted logistic regression In this problem you will implement a locally-weighted version of logistic regression, where we weight different training examples differently according to the query point. The locally-weighted logistic regression problem is to maximize ℓ(θ) = − λ 2 θTθ + Xm i=1 w(i) h y(i) logh θ(x (i))+(1−y ...
Lecture 5 Least-squares - Stanford Engineering Everywhere
see.stanford.eduLeast-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
