WitrynaThe Naïve Bayes classifier is a supervised machine learning algorithm, which is used for classification tasks, like text classification. It is also part of a family of generative learning algorithms, meaning that it seeks to model the distribution of inputs of a given class or category.

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. heather williams young and the restlessWitrynaPlease help me.
