In biology
and ontology,
classification is the act of a human placing an object
or concept into a taxonomy.
For biologists, species
are specifically placed into a biological taxonomy.
In statistics
and machine
learning, classification is a type of statistical
algorithm, which takes a feature representation of an
object or concept and maps it to a classification label.
Typically, a classification algorithm computes a posterior
probability: the probability of a class label, given
that the feature input was observed. (See supervised
learning).
