This class is used to initialize the weight matrix with the method proposed by T.
Kathirvalavakumar and S. Subavathi. The method is based on sensitivity analysis using using cauchy’s inequality. The method is defined by
where I is the number of inputs including the bias, p refers the pattern considered in training, f is the transfer function and \={s} is the active region in which the derivative of the activation function is greater than 4% of the maximum derivatives.
