在经典ＢＰ网络￣［１］基础上，将线性连接权值改为非线性权值，激活函数分别使用Ｓｉｇｍｏｉｄ函数和Ｃｈｅｂｙｓｈｅｖ多项式构成ＳＢＰ和ＣＢＰ，分析网络的性能，并用计算机进行仿真实验给出仿真结果。
On the basis of the classical BP network [1], the weight of linear connection is changed to non-linear weight. The activation function uses Sigmoid function and Chebyshev polynomial to form SBP and CBP, respectively. The performance of the network is analyzed, and simulation is given by computer to simulate result.
