It is a linear method as described above in equation $\eqref{eq:regPrimal}$, with the loss function in the formulation given by the logistic loss: \[ L(\wv;\x,y) := \log(1+\exp( -y \wv^T \x)). \] For binary classification problems, the algorithm outputs a ... bwr asx

"NettetLogistic regression is an algorithm that learns a model for binary classification. A nice side-effect is that it gives us the probability that a sample belongs to class 1 (or vice versa: class 0). Our objective function is to minimize the so-called logistic function Φ (a certain kind of sigmoid function); it looks like this: " - Linear classification vs logistic regression
