英文摘要：

To solve the slow converge efficiency and easier to fall into the flat area in the training of neural network, a improved momentum BP algorithm with an odd parameter was proposed. Under the convergence and train precision which was demanded, it can save time through reducing the calculation, it can also increase the convergence speed through increasing the grads. In this paper, it argument the validity in detail,and its capabilities are validated by experimentations finally. The new algorithm can save the training time about 9.65% and training step was also decreased about 31. 13% in the experimentations than the traditional BP algorithm. It is suitable for demanding about Real-time with the dynamic flow measure.
