In this paper, a gradient method with momentum for sigma-pi-sigma neural networks (SPSNN) is considered in order to accelerate the convergence of the learning procedure for the network weights. The momentum coefficient is chosen in an adaptive manner, and the corresponding weak convergence and strong convergence results are proved. 展开更多

作者 张迅 《温州大学学报(自然科学版)》 2018年第2期17-21,共5页
对Sigma-Pi-Sigma神经网络(简称SPSNN)的固定学习率梯度算法,引入动量项更新,以期待改善其收敛性.在可变动量项因子的情形,对带动量项的梯度算法进行了确定型收敛性的研究,给出了误差函数的单调性结果,并得到了该算法的弱收敛性定理.
