Method Detail

can_build

public hex.ModelCategory[] can_build()

Specified by:

can_build in class hex.ModelBuilder<CoxPHModel,CoxPHModel.CoxPHParameters,CoxPHModel.CoxPHOutput>

builderVisibility

public hex.ModelBuilder.BuilderVisibility builderVisibility()

Specified by:

builderVisibility in class hex.ModelBuilder<CoxPHModel,CoxPHModel.CoxPHParameters,CoxPHModel.CoxPHOutput>

schema

public hex.schemas.ModelBuilderSchema schema()

Specified by:

schema in class hex.ModelBuilder<CoxPHModel,CoxPHModel.CoxPHParameters,CoxPHModel.CoxPHOutput>

trainModelImpl

public water.Job<CoxPHModel> trainModelImpl(long work)

Start the Cox PH training Job on an F/J thread.

Specified by:

trainModelImpl in class hex.ModelBuilder<CoxPHModel,CoxPHModel.CoxPHParameters,CoxPHModel.CoxPHOutput>

Parameters:

work -

progressUnits

public long progressUnits()

Specified by:

progressUnits in class hex.ModelBuilder<CoxPHModel,CoxPHModel.CoxPHParameters,CoxPHModel.CoxPHOutput>

init

public void init(boolean expensive)

Initialize the ModelBuilder, validating all arguments and preparing the training frame. This call is expected to be overridden in the subclasses and each subclass will start with "super.init();". This call is made by the front-end whenever the GUI is clicked, and needs to be fast; heavy-weight prep needs to wait for the trainModel() call.

Overrides:

init in class hex.ModelBuilder<CoxPHModel,CoxPHModel.CoxPHParameters,CoxPHModel.CoxPHOutput>
