摘要
本文提出了一种基于神经网络的分形模型,讨论了映射收缩条件,并对湖底回波进行了实验。实验结果表明,在此基础上求解分形逆问题,得到的吸引子能很好地逼近指定信号。
A new method to resolve fractal inverse problem based on neural network was presented in this paper which can be employed to model a time sequences.The precondition to assure the model was also provided. A piece of echo from a lake was taken to test the algorithm. The result is satisfying.
