org.encog.ml.train.BasicTraining

org.encog.neural.cpn.training.TrainInstar

All Implemented Interfaces:

MLTrain, LearningRate

public class TrainInstar
extends BasicTraining
implements LearningRate

Used for Instar training of a CPN neural network. A CPN network is a hybrid supervised/unsupervised network. The Instar training handles the unsupervised portion of the training.

Constructor Detail

TrainInstar

public TrainInstar(CPN theNetwork,
                   MLDataSet theTraining,
                   double theLearningRate,
                   boolean theInitWeights)

Construct the instar training object.

Parameters:

theNetwork - The network to be trained.

theTraining - The training data.

theLearningRate - The learning rate.

theInitWeights - True, if the weights should be initialized from the training data. If set to true, then you must have the same number of training elements as instar neurons.
