Classifier (mathematics)

A classifier is originally a kind cataloguer in the library world. General classifier called an instance that classifies objects, that is, in categories classifies.

What is the nature of such a body, is dependent on the considered scenario: In computer science, a classifier is often an algorithm or a program object, especially in pattern recognition, a mathematical function that maps a feature space to a set of classes. Also, mechanical components, for example for sorting coins by size, classifiers can represent.

In many cases, the distinction between process and instance is not necessary or useful, which is why the term classifier is often used synonymously with classification methods.
