Class GridSearchHandler<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

jsr166y.ForkJoinTask<java.lang.Void>

jsr166y.CountedCompleter

water.H2O.H2OCountedCompleter

water.api.Handler

hex.api.GridSearchHandler<G,S,MP,P>

Type Parameters:

G - Implementation output of grid search

MP - Type of model parameters

P - Type of schema representing model parameters

S - Schema representing structure of grid search end-point

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, java.util.concurrent.Future<java.lang.Void>, water.Freezable

Direct Known Subclasses:

public abstract class GridSearchHandler<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.Handler

A generic grid search handler implementing launch of grid search.

A model specific grid search handlers should inherit from class and implements corresponding methods. FIXME: how to get rid of P, since it is already enforced by S

validateHyperParams

protected void validateHyperParams(P params,
                       java.util.Map<java.lang.String,java.lang.Object[]> hyperParams)

Validate given hyper parameters with respect to type parameter P. It verifies that given parameters are annotated in P with @API annotation

Parameters:

params - regular model build parameters

hyperParams - map of hyper parameters
