water.Iced

hex.ModelBuilder<GenericModel,GenericModelParameters,GenericModelOutput>

hex.generic.Generic

All Implemented Interfaces:

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

public class Generic
extends hex.ModelBuilder<GenericModel,GenericModelParameters,GenericModelOutput>

Generic model able to do scoring with any underlying model deserializable into a format known by the GenericModel. Only H2O Mojos are currently supported.

                                           boolean disableAlgoCheck)

Convenience method for importing MOJO into H2O.

Parameters:

location - absolute path to MOJO file

disableAlgoCheck - if true skip the check of white-listed MOJO models, use at your own risk - some features might not work.

Returns:

instance of H2O Model wrapping a MOJO
