摘要
结合程序代码论述了1个手写体数字识别程序的原理。该识别程序应用了神经网络来实现其功能,采用BP网络。主要论及了关于BP网络的3个问题:反向传播算法;提高BP网络收敛速度的算法;以及文中提出的对网络进行修剪以期能改善其推广能力的1种算法。
This paper presents a theory of program to recognize handwriting digits.Artificial Neural network was applied in the program,and BP network was used.So the paper mainly discusses three aspects of BP network,including back propagation algorithm,algorithm to ac-celerate the running speed of the program,and algorithm to cut those uselessness weights in order to better the generalization of the network.
