The multinomial Naive Bayes classifier is suitable for classification with discrete features (e.g., word counts for text classification). The multinomial distribution normally requires integer feature counts. However, in practice, fractional counts such as tf-idf may also work.
Witryna12 kwi 2024 · Naive Bayes Classifier. First, let’s get to the basics of Naive Bayes classification. Let’s denote the features as X and the label as y. As a generative model, the naive Bayes classifier makes predictions based on estimation of the joint probability P(X,y). For each example, the predicted label is determined by:
