T1-01编写程序，计算下面级数前N项中奇数项的和OS。在求和过程中，以第一个数值小于0.0001的项为末项，输出和数0s。（其中^表示幂运算） 答案：s=0.192675035774713423-T1-01 programming, the former calculation below Series N odd item and the item OS. In summation process, the first one is less than 0.0001 for the en

自然梯度算法比随机梯度算法有更好的收敛性能和数值稳定性，块递归算法需要较少的运算时间。(The natural gradient algorithm works more efficiently than the ordinary gradient algorithm, and the block recursive method is feasible to real-time processing.)
