Witryna27 kwi 2024 · Not all classification predictive models support multi-class classification. Algorithms such as the Perceptron, Logistic Regression, and Support Vector Machines were designed for binary classification and do not natively support classification tasks with more than two classes. Witrynathe use of multinomial logistic regression for more than two classes in Section5.3. We’ll introduce the mathematics of logistic regression in the next few sections. But let’s begin with some high-level issues. Generative and Discriminative Classifiers: The most important difference be-tween naive Bayes and logistic regression is that ...
