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.

Witryna12 kwi 2024 · Naïve Bayes (NB) classifier is a well-known classification algorithm for high-dimensional data because of its computational efficiency, robustness to noise [ 15 ], and support of incremental learning [ 16, 17, 18 ]. This is not the case for other machine learning algorithms, which need to be retrained again from scratch. Witryna3.4.1. Configuration Used for the Naïve Bayes Model The Weka tool has different classifiers, and they are grouped together depending upon their similarities.
