Package

weka.classifiers.bayes

Class for building and using a Discriminative Multinomial Naive Bayes classifier. For more information see,

Jiang Su,Harry Zhang,Charles X. Ling,Stan Matwin: Discriminative Parameter Learning for Bayesian Networks. In: ICML 2008', 2008.

The core equation for this classifier:

P[Ci|D] = (P[D|Ci] x P[Ci]) / P[D] (Bayes rule)

where Ci is class i and D is a document.

Available in Weka 3.6.x - 3.7.1. Available via the package management system for Weka >= 3.7.2 (DMNBtext)
