Class IndexRangeSegregator

java.lang.Object

org.encog.util.normalize.segregate.index.IndexSegregator

org.encog.util.normalize.segregate.index.IndexRangeSegregator

All Implemented Interfaces:

java.io.Serializable, Segregator

public class IndexRangeSegregator
extends IndexSegregator

An index segregator is used to segregate the data according to its index. Nothing about the data is actually compared. This makes the index range segregator very useful for breaking the data into training and validation sets. For example, you could very easily determine that 70% of the data is for training, and 30% for validation. This segregator takes a starting and ending index. Everything that is between these two indexes will be used.
