Method Detail

getTrainingSet

public TrainingSet getTrainingSet()

Description copied from interface: Trainable

Returns the the training set, which contains input and target data.

Specified by:

getTrainingSet in interface Trainable

Returns:

the training set.

getNetwork

public Group getNetwork()

Description copied from interface: Trainable

Returns a reference to the subnetwork or synapse group being trained.

Specified by:
