| 英文摘要 |
| Based on clustering
and support vector machines, a new method is proposed to
solve the nonlinear time series fault prediction. The normal time series is clustered using K-means clustering
algorithm to get the normal prototype. Meanwhile, the predicting series is obtained by time series predicting
algorithm based on support vector regression. Fault prediction can also be implemented by calculating the
similarity between the normal prototype and the predicting series. Finally, the simulation results indicate
that the proposed method can predict the fault more quickly and more accurately. |
