Relaxed conditions for convergence of batch BPAP for feedforward neural networks
In this paper, the deterministic convergence of the batch back-propagation algorithm with penalty (BPAP) is proved under certain relaxed conditions for the activation function, the learning rate and the stationary point set of the error function. Both weak and strong convergence results are established. The boundedness of the weights in the training procedure is also proved in a simple and clear way. As a result, the usual requirements on the boundedness of the weights to guarantee the convergence are removed. Simulation results for an approximation problem are presented to support our theoretical findings.
