It is shown that modifying the sigmoidal basisfunction of a multi-layer feedforward artificial neural network using a control parameter improves the network's ability to learn. The modification is rendered by a gradient descent algorithm similar to the back-propagation. In doing so, the method retains all the goodies of the sigmoidal function and causes the ANN to approximate the decision function faster and also with better accuracy. (C) 2002 Elsevier Science B.V.
