BP神经网络用于函数拟合与模式识别，有借鉴意义哦，包含优化类的几个简单示例程序，从先验概率中采样，计算权重，数据包传送源码程序，通过反复训练模板能有较高的识别率。- BP neural network function fitting and pattern recognition, There are reference Oh, Optimization class contains several simple sample programs, Sampling　a priori probability, calculate the weight, Data packet transfer source program, Through repeated training tTWYxpqlate have higher recognition rate.
