  • How to Find Linear (SVMs) and Quadratic Classifiers

    2019-5-20 · Another approach to linear classification is the logistic regression model, which, despite its name, is a classification rather than a regression method. Logistic regression models the probabilities of an observation belonging to each of the K classes via linear functions, ensuring these probabilities sum up to one and stay in the (0, 1) range.
