A new structure and training method for multilayer neural networks is presented. The proposed method is based on cascade training of subnetworks and optimizing weights layer by layer. The training procedure is completed in two steps. First, a subnetwork, m inputs and n outputs as the style of training samples, is trained using the training samples. Secondly the outputs of the subnetwork is taken as the inputs and the outputs of the training sample as the desired outputs, another subnetwork with n inputs and n outputs is trained. Finally the two trained subnetworks are connected and a trained multilayer neural networks is created. The numerical simulation results based on both linear least squares back-propagation (LSB) and traditional back-propagation (BP) algorithm have demonstrated the efficiency of the proposed method.
提出了一种用于多层神经网络的新结构和训练方法。该方法基于子网络的级联训练和逐层权重优化。训练过程分两步完成。首先,以具有m个输入和n个输出的子网络作为训练样本的样式,使用训练样本进行训练。其次,将子网络的输出作为输入,训练样本的输出作为期望输出,训练另一个具有n个输入和n个输出的子网络。最后,将两个训练好的子网络连接起来,创建一个训练好的多层神经网络。基于线性最小二乘反向传播(LSB)和传统反向传播(BP)算法的数值模拟结果证明了该方法的有效性。
