Class SubModelBuilder

java.lang.Object

hex.SubModelBuilder

public class SubModelBuilder
extends java.lang.Object

Execute build of a collection of sub-models (CV models, main model) in parallel This class is conceptually similar to CVModelBuilder and follows the same API. As opposed to CVModelBuilder it is not limited to building just CV models but can built a mixture of CV and main models. It also uses more efficient technique of model parallelization that works better when different sub-models (eg. CV folds) take vastly different time to complete. It currently lacks prepare/finished feature of CVModelBuilder
