Constructor Detail

WeightMatrix

public WeightMatrix(int unitsLeftLayer,
                    int unitsRightLayer)

Creates a [unitsRightLayer x (unitsLeftLayer + 1)] matrix of weights and seed the values using the famous uniform distribution formula of LeCun. Which is calculating the deviation of the weights by SQRT(6)/((num units left layer)+(num units right layer)) and distributing them with zero mean.
