Statistical classification

In statistics, classification is the problem of identifying which of a set of categories (sub-populations) an observation, (or observations) belongs to. Examples are assigning a given email to the "spam" or "non-spam" class, and assigning a diagnosis to a given patient based on observed characteristics of the patient (sex, blood pressure, presence or absence of certain symptoms, etc.).
