英文摘要：

The chaotic time series prediction is an important research orientation in signal processing and automatic control areas. The neural network learning algorithms show a significant advantage in solving high complex and strong nonlinear problems. A good learning algorithm for feedforward neural networks named extreme learning machine （ELM） was applied to chaotic time series prediction. Compared with resource allocating network （RAN） learning algorithm, the simulation results show that ELM learning algorithm can achieve satisfactory prediction performance with a fast learning speed. And the choice of the activation functions of ELM learning algorithm is data set dependent.
