Class IntegerBalanceSegregator

java.lang.Object

org.encog.util.normalize.segregate.IntegerBalanceSegregator

All Implemented Interfaces:

java.io.Serializable, Segregator

public class IntegerBalanceSegregator
extends java.lang.Object
implements Segregator

Balance based on an input value. This allows you to make sure that one input class does not saturate the training data. To do this, you specify the input value to check and the number of occurrences of each integer value of this field to allow.
