| 摘 要： | 鉴于传统BP算法不能动态修改权值的缺陷，引入了时间差分算法(Temporal Difference)^[1]，然后提出了将TD法与BP法相结合的一种基于神经网络的预测算法，并由此来解决在时间序列预测中的权值动态修改问题。本文推导出二者如何结合的公式，并给出了相应的C 实现方法。通过对一个时序信号的建模仿真说明该算法的可行性。 |

| Abstract: | Whereas the standard BP algorithm can not change weight dynamically, Temporal Difference (TD) method is introduced. This paper applies a learning algorithm based on neural network to predict time sequence. We deduct the algorithm which combines TD method with BP net and give a method to perform the algorithm by C++. Through a simulation in which we build a model for signal of time sequence, we illuminate the feasibility of this algorithm. |
| Keywords: | modelling neural network time sequence temporal difference BP net |
