1.引言前馈神经网络是目前应用最广的一种神经网络,其学习算法是由Rumelhart等人于1986年提出的反向传播(Back Propagation,BP)算法,故这种神经网络也常被称为BP神经网络。人们对前馈神经网络学习算法的研究,以前主要着重对各层之间联接权值优化的研究,如BP算法以 1. Introduction Feedforward neural network is the most widely used neural network, the learning algorithm is backpropagation (BP) algorithm proposed by Rumelhart et al in 1986, so this neural network is also often Called BP neural network. People research on the feedforward neural network learning algorithm, the previous focus mainly on optimization of the connection between the layers of research, such as the BP algorithm to
