Method Detail

getTargetEncoderModel

public TargetEncoderModel getTargetEncoderModel()

init

public void init(boolean expensive)

Overrides:

init in class hex.ModelBuilder<TargetEncoderModel,TargetEncoderModel.TargetEncoderParameters,TargetEncoderModel.TargetEncoderOutput>

ignoreInvalidColumns

protected void ignoreInvalidColumns(int npredictors,
                                    boolean expensive)

Overrides:

ignoreInvalidColumns in class hex.ModelBuilder<TargetEncoderModel,TargetEncoderModel.TargetEncoderParameters,TargetEncoderModel.TargetEncoderOutput>

nFoldCV

public boolean nFoldCV()

Never do traditional cross-validation for Target Encoder Model. The TargetEncoder class handles fold column on it's own.

Overrides:

nFoldCV in class hex.ModelBuilder<TargetEncoderModel,TargetEncoderModel.TargetEncoderParameters,TargetEncoderModel.TargetEncoderOutput>

Returns:

Always false

trainModelImpl

protected hex.ModelBuilder.Driver trainModelImpl()

Specified by:

trainModelImpl in class hex.ModelBuilder<TargetEncoderModel,TargetEncoderModel.TargetEncoderParameters,TargetEncoderModel.TargetEncoderOutput>

can_build

public hex.ModelCategory[] can_build()

Specified by:

can_build in class hex.ModelBuilder<TargetEncoderModel,TargetEncoderModel.TargetEncoderParameters,TargetEncoderModel.TargetEncoderOutput>

isSupervised

public boolean isSupervised()

Specified by:

isSupervised in class hex.ModelBuilder<TargetEncoderModel,TargetEncoderModel.TargetEncoderParameters,TargetEncoderModel.TargetEncoderOutput>

builderVisibility

public hex.ModelBuilder.BuilderVisibility builderVisibility()

Overrides:

builderVisibility in class hex.ModelBuilder<TargetEncoderModel,TargetEncoderModel.TargetEncoderParameters,TargetEncoderModel.TargetEncoderOutput>

haveMojo

public boolean haveMojo()

Overrides:

haveMojo in class hex.ModelBuilder<TargetEncoderModel,TargetEncoderModel.TargetEncoderParameters,TargetEncoderModel.TargetEncoderOutput>

getName
