Witryna15 maj 2016 · The main purpose of this paper is to borrow from the research achievements about feature weighting algorithms of standard naive Bayes classifiers to improve naive Bayes text classifiers. In this paper, we adapt two simple, efficient, and effective feature weighting approaches to naive Bayes text classifiers. One is the … WitrynaNaive Bayes methods are a set of supervised learning algorithms based on applying Bayes’ theorem with the “naive” assumption of conditional independence between every pair of features given the value of the class variable. Bayes’ theorem states the following relationship, given class variable y and dependent feature vector x 1 through x n, :
