What is classification?
Classification is the process of assigning every object from a collection to exactly one class from a known set of classes.
Examples of classification tasks are:
assigning a patient (the object) to a group of healthy or ill (the classes) people on the basis of his or her medical record,
determining the customer’s (the object) credibility during credit application using, for example, demographic and financial data; in this case the classes are „credible” and „not credible”,
determining if the customer (the object) is likely to stop using the company’s services or products on the basis of behavioral and demographic data; in this case the classes are „disloyal customers” and „loyal customers”.
