Lecture 3 Linear Equations and Matrices

so multiplication by matrix inverse solves a set of linear equations some comments: • x = A−1b makes solving set of 100 linear equations in 100 variables look simple, but the notation is hiding alot of work!

we decide to approximate y as a linear function of x: hθ(x) = θ0 +θ1x1 +θ2x2 Here, the θi’s are the parameters (also called weights) parameterizing the space of linear functions mapping from X to Y. When there is no risk of confusion, we will drop the θ …

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

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

Introduction to Global Optimization

MILPs are very different from those for solving LPs. Typically, the solution of an entire LP problem (obtained by relaxing the integrality constraints on the integer variables, and called the LP relaxation) is required at each step of an algorithm that solves a MILP. The two most common algorithms employed in
