training example (x(i);y(i)), we de ne the functional margin of (w;b) with respect to the training example ^ (i)= y (wTx+b): Note that if y(i) = 1, then for the functional margin to be large (i.e., for our prediction to be con dent and correct), then we need wTx+b to be a large positive number. Conversely, if y(i) = 1, then for the functional ...

CS229 Lecture notes - Stanford Engineering Everywhere
see.stanford.eduwe 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 ...
