hex.schemas

Class GridSearchSchema<G extends hex.grid.Grid<MP>,S extends GridSearchSchema<G,S,MP,P>,MP extends hex.Model.Parameters,P extends water.api.ModelParametersSchema>

java.lang.Object

water.Iced

water.api.Schema<G,S>

hex.schemas.GridSearchSchema<G,S,MP,P>

Type Parameters:

G - a specific implementation type for GridSearch holding results of grid search (model list)

S - self type

MP - actual model parameters type

P - a specific model builder parameters schema, since we cannot derive it from P

All Implemented Interfaces:

java.io.Externalizable, java.io.Serializable, java.lang.Cloneable, water.Freezable

Direct Known Subclasses:

DeepLearningGridSearchV99, DRFGridSearchV99, GBMGridSearchV99, GLMGridSearchV99, GLRMGridSearchV99, KMeansGridSearchV99, NaiveBayesGridSearchV99, PCAGridSearchV99, SVDGridSearchV99

public class GridSearchSchema<G extends hex.grid.Grid<MP>,S extends GridSearchSchema<G,S,MP,P>,MP extends hex.Model.Parameters,P extends water.api.ModelParametersSchema>
extends water.api.Schema<G,S>

This is a common grid search schema composed of two parameters: default parameters for a builder and hyper parameters which are given as a mapping from parameter name to list of possible values.
