Multinomial Naїve Bayes' For Documents Classification and Natural Language Processing (NLP)

It's formulated as several methods, widely used as an alternative to the distance-based K-Means clustering and decision tree forests, and deals with probability as the "likelihood" that data belongs to a specific class. The Gaussian and Multinomial models of the naïve Bayes exist. The multinomial model provides an ability to classify data, that cannot be represented numerically. Its main advantage is the significantly reduced complexity. It provides an ability to perform the classification, using small training sets, not requiring to be continuously re-trained.
