Constructor Detail

FreeformBackPropagation

public FreeformBackPropagation(FreeformNetwork theNetwork,
                       MLDataSet theTraining,
                       double theLearningRate,
                       double theMomentum)

Construct a back propagation trainer.

Parameters:

theNetwork - The network to train.

theTraining - The training data to use. The coefficient for how much of the gradient is applied to each weight.

theLearningRate - The learning rate. The coefficient for how much of the previous delta is applied to each weight. In theory, prevents local minima stall.

theMomentum - The momentum.
