Class OutputOneOf

java.lang.Object

org.encog.util.normalize.output.BasicOutputField

org.encog.util.normalize.output.nominal.OutputOneOf

All Implemented Interfaces:

java.io.Serializable, OutputField

public class OutputOneOf
extends BasicOutputField

An output field that uses the "on of" technique to represent input data. For example, if there were five nominal items, or classes, given then each one would be represented by a single output neuron that would be on or off. Often the OutputEquilateral class is a better choice to represent nominal items.
