Method Detail

getType

java.lang.String getType()

prepare

void prepare()

preprocessing steps are prepared by default before the AutoML session starts training the first model.

apply

PreprocessingStep.Completer apply(hex.Model.Parameters params,
                                  PreprocessingConfig config)

applies this preprocessing step to the model parameters right before the model training starts.

Parameters:

params -

Returns:

a function used to "complete" the preprocessing step: it is called by default at the end of the job creating model(s) from the given parms. This can mean for example cleaning the temporary artifacts that may have been created to apply the preprocessing step.

dispose

void dispose()

preprocessing steps are disposed by default at the end of the AutoML training session. Note that disposing here doesn't mean being removed from the system, the goal is mainly to clean resources that are not needed anymore for the current AutoML run.

remove

void remove()

Completely remove from the system
