public class GHAModel
extends AbstractEigenvectorModel
implements 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:

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