Bayes classifier

Bayesian methods

A machine learning thing. Related to Naive Bayes classifier.

It's one way to approach a classification problem.

BTW, terminology is varied. The term classifier can be meant as:

1. a mathematical function that maps input data to a category
2. an algorithm that implements classification, esp. in a concrete implementation

In stats, classification is often done via logistic regression, speaking of explanatory/independent vars, and the possible categories are termed outcomes. In ML, observations are often known as instances, the explanatory vars as features, and the possible categories are termed classes.
