isSupervised

public boolean isSupervised()

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 response column; move it to the end; flip it to an Categorical if requested. Validate the max_after_balance_size; compute the number of classes.

Overrides:

init in class ModelBuilder<M extends SupervisedModel<M,P,O>,P extends SupervisedModel.SupervisedParameters,O extends SupervisedModel.SupervisedOutput>
