## 76: Probabilistic Classifiers

December 27, 2016

Posted by on As used in machine learning, the term **probabilistic classifier **refers to a function , where is the set of objects to be classified, is the set of classes, and is the set of probability distributions over . That is, a probabilistic classifier takes an object to be classified and gives the probability of that object belonging to each of the possible classes.

This contrasts with a *non-probabilistic classifier*, which instead is simply a function that assigns a single class given an object. Often, the choice is simply that category with the highest probability.
