                  edu.udo.cs.yale.operator.features.transformation.GHAModel

All Implemented Interfaces:

ComponentWeightsCreatable, IOObject, Model, ResultObject, Saveable, java.awt.event.ActionListener, java.awt.event.ItemListener, java.util.EventListener

public class GHAModel
extends IOModel
implements java.awt.event.ActionListener, java.awt.event.ItemListener, ComponentWeightsCreatable

This is the transformation model of the GHA The number of components is initially specified by the GHA. Additionally the user can specify a lower number in the ModelApplier. You can add two prediction parameter:

• nr_components integer Specify a lower number of components
• keep_attributes true|false If true, the original features are not removed.
