There are two broad classes of methods for determining the parameters of a linear classifier . They can be generative and discriminative models. Methods of the former model joint probability distribution, whereas methods of the latter model conditional density functions . Examples of such algorithms include: • Linear Discriminant Analysis (LDA)—assumes Gaussian conditional density models WebThe linear regression that we previously saw will predict a continuous output. When the target is a binary outcome, one can use the logistic function to model the probability. …
