| Abstract: | Product unit neural network is one kind of Higher-Order neural network with exponential weights.Due to the special structure with exponential weights,it can provide more powerful internal representation capability than traditional feed-forward neural networks.In this paper,a convergence result for an online gradient method to train product unit neural networks is presented.The monotonicity of the error function during the training iteration process is also guaranteed. The experiment results are given by the... |
