| Abstract: | A method of chaotic time series prediction problem based on local dynamical similarity is proposed.The method is concerned with the local similarity of the predicted points,and avoids the traditional analogue functions and data analysis.The method is applied to the forecast of the time series data of Lorenz system,and the forecast results show that the method is both simple and practicable. |
