中文说明： 为检验支持向量机非线性回归的泛化能力，BP神经网络有着很强的非线性拟合能力，能以任意精度逼近任意非线性连续函数，当然其前提条件是——神经网络构造适当并且训练充分。
English Description：
&In order to test the generalization ability of nonlinear regression of support vector machine, BP neural network has strong nonlinear fitting ability and can approximate any nonlinear continuous function with any precision. Of course, the premise is that the neural network is constructed properly and trained sufficiently.
