In this paper, we review some of these improved algorithms and single out four main improved approaches: 1) Feature selection; 2) Structure extension; 3) Local learning; 4) Data expansion.
Witryna12 lut 2024 · In summary, we have described a method for enhancing the predictive accuracy of naive Bayes for regression. The approach employs “real” training data only indirectly in the machine learning pipeline, as part of a fitness function that in turn is used to optimize a small artificial surrogate training dataset. Witryna11 wrz 2024 · The Naive Bayes algorithm is one of the most popular and simple machine learning classification algorithms. It is based on the Bayes’ Theorem for calculating probabilities and conditional …
Witryna10 kwi 2024 · We're trying to implement a semantic searching algorithm to give suggested categories based on a user's search terms. At the moment we have … WitrynaDue to its simplicity, efficiency, and effectiveness, multinomial naive Bayes (MNB) has been widely used for text classification. As in naive Bayes (NB), its assumption of the conditional independence of features is often violated and, therefore, reduces its classification performance. Of the numerous approaches to alleviating its assumption …
Witryna17 gru 2024 · Naive Bayes is a classification technique that is based on Bayes’ Theorem with an assumption that all the features that predicts the target value are independent …
WitrynaMany kinds of machine learning algorithms are used to build classifiers. This chapter introduces naive Bayes; the following one introduces logistic regression. These exemplify two ways of doing classification. Generative classifiers like naive Bayes build a model of how a class could generate some input data.
