BP网络的统计意义及实例分析

作为计算机理论与技术发展的产物之一－神经网络，对它的研究正方兴未艾，其中，BP网络的应用研究越来越广泛。从软件工程学的角度，BP网络是一个“黑匣子”，但事实上，它具有深刻的数学意义。本推导了BP网络是传统回归模型的推广，具有广阔的应用前景，并给出了应用实例，进一步揭示了BP网络具有传统统计方法不可替代的作用。

Statistical View on BP Network and An Example

Now many people are studying neural network which is one of the products of the development of computer theory and technology.The BP network,one of neural networks,has been successfully applied to many fields.From the view of Software Engineering,the BP network is a black box.But in fact,it is of deep significance in Maths.This paper proves that the BP network is the generalization of tradictional regressive model.And it would be of broad applied uses.At the same time,an applied example was given.It was progressively indicated that the work of the BP network was not substituted by tradictional statistical method.
