It is suggested to use the adaptive regularization scheme in conjunction with Optimal Brain Damage pruning to optimize the architecture and to avoid overfitting. Furthermore, we propose an improved neural classification architecture eliminating an inherent redundancy in the widely used SoftMax classification network. Numerical results demonstrate the viability of the method. In proccedings of the IEEE Workshop on Neural Networks for Signal Processing VII, IEEE Press, 1997.
