Method Detail
trainModelImpl

protected hex.grep.Grep.GrepDriver trainModelImpl()

Specified by:
trainModelImpl in class hex.ModelBuilder

can_build

public hex.ModelCategory[] can_build()

Specified by:
can_build in class hex.ModelBuilder

builderVisibility

public hex.ModelBuilder.BuilderVisibility builderVisibility()

Overrides:
builderVisibility in class hex.ModelBuilder

isSupervised

public boolean isSupervised()

Specified by:
isSupervised in class hex.ModelBuilder

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. Validate the regex.

Overrides:
init in class hex.ModelBuilder
