Method Detail

parent

public Estimator<M> parent()

The parent estimator that produced this model. Note: For ensembles' component Models, this value can be null.

Returns:

(undocumented)

setParent

public M setParent(Estimator<M> parent)

Sets the parent of this model (Java API).

Parameters:

parent - (undocumented)

Returns:

(undocumented)

hasParent

public boolean hasParent()

Indicates whether this Model has a corresponding parent.

copy

public M copy(ParamMap extra)

Description copied from interface: Params

Creates a copy of this instance with the same UID and some extra params. The default implementation tries to create a new instance with the same UID. Then it copies the embedded and extra parameters over and returns the new instance. Subclasses should override this method if the default approach is not sufficient.

Specified by:

copy in interface Params

Overrides:

copy in class Transformer

Parameters:

extra - (undocumented)

Returns:

(undocumented)
