## Naive bayes

In machine learning, naive bayes classifiers are a family of simple probabilistic classifiers based on applying bayes' theorem with strong (naive) independence . The naivebayes type exposes the following members constructs a new naïve bayes classifier public method, naivebayes(int32,double[],int32[]), obsolete. Method for classify determines the class using bayes's theorem and assuming that features are independent given the class.

Oct 4, 2014 by sebastian raschka naive bayes classifiers, a family of classifiers that are based on the popular bayes' probability theorem, are known for.

Computes the conditional a-posterior probabilities of a categorical class variable given independent predictor variables using the bayes rule. Naïve bayes is a classification algorithm that relies on strong assumptions of the independence of covariates in applying bayes theorem the naïve bayes. Naive bayes methods are a set of supervised learning algorithms based on applying bayes' theorem with the “naive” assumption of independence between. Next, we shall discuss some math about posterior probability also known as bayes theorem this is core part of naive bayes classifier at last.
