WitrynaAn approach to overcome this ‘zero-frequency problem’ is to add one to the count for every attribute value-class combination when an attribute value doesn’t occur with every class value. This will lead to the removal of all the zero values from the classes and, at the same time, will not impact the overall relative frequency of the classes.

Witryna25 maj 2024 · Naive Bayes is a family of probabilistic algorithms that take advantage of probability theory and Bayes’ Theorem to predict the tag of a text (like a piece of news or a customer review). They are probabilistic, which means that they calculate the probability of each tag for a given text, and then output the tag with the highest one.

Witryna30 mar 2013 · NAIVE BAYES CLASSIFIER. Bayes methods are also used as one of the classification solutions in data mining. In our work we use six main Bayesian methods namely AODE, AODEsr, Naive Bayes, Bayesian net, Naive Bayes simple and Naive Bayes updateable, that are implemented in WEKA software for classification. WitrynaTo generate classification results for fusion, the open source software package WEKA is used to apply the classification methods. The different hyperparameters of each classifier are not considered, so the default-parametrization is used. The optimization of classifier inherent parameters is a highly problem specific task .
