Backpropagation_Quickprop

代码说明：

  一种简单的利用二阶信息来提高训练速度的快速传播算法，权值假设为独立的，下降过程可以对每个权值进行优化。(Use of a simple second-order information to improve the training speed of the fast-propagation algorithm, the right value is assumed to be independent, the process can decrease the value of each right to be optimized.)
