Direct Known Subclasses:

MetricFeature

public abstract class Feature<T extends org.apache.hadoop.io.Writable>
extends Object
implements org.apache.hadoop.io.Writable

A feature models defining properties of a thing. These defining properties generally take on the form of some mathematical representation that can be used for machine learning, trending, and other statistical analysis. This model of a feature provides some common identification information as well as a vector that houses the actual mathematical summary data.
