Method Detail

score0

public double[] score0(double[] row,
                       double[] preds)

Description copied from class: GenModel

Subclasses implement the scoring logic. The data is pre-loaded into a re-used temp array, in the order the model expects. The predictions are loaded into the re-used temp array, which is also returned. This call exactly matches the hex.Model.score0, but uses the light-weight GenModel class.

Specified by:

score0 in class GenModel

internal_threadSafeInstance

public GenModel internal_threadSafeInstance()

Description copied from class: GenModel

For internal use only - can be removed at any time! Creates a version of the MOJO that can be used by a thread in a multi-threaded environment. This is a temporary workaround and proper fix should be put in place for the MOJOs that are not currently thread safe (GAM).

Overrides:

internal_threadSafeInstance in class GenModel

makeConverterFactory

public RowToRawDataConverter makeConverterFactory(java.util.Map<java.lang.String,java.lang.Integer> modelColumnNameToIndexMap,
                                                  java.util.Map<java.lang.Integer,CategoricalEncoder> domainMap,
                                                  EasyPredictModelWrapper.ErrorConsumer errorConsumer,
                                                  EasyPredictModelWrapper.Config config)

Specified by:

makeConverterFactory in interface ConverterFactoryProvidingModel

Returns:

A new instance of RowToRawDataConverter related to the underlying GenModel
