Building a simple classifier

A classifier is a system with some characteristics that allow you to identify the class of the sample examined. In different classification methods, groups are called classes. The goal of a classifier is to establish the classification criterion to maximize performance. The performance of a classifier is measured by evaluating the capacity for generalization. Generalization means attributing the correct class to each new experimental observation. The way in which these classes are identified discriminates between the different methods that are available.
