| 英文摘要 |
| The division of fuzzy interval plays a very important role to the final prediction accuracy when one uses
the fuzzy time series prediction model to prediction. In order to solve the problem of how to divide fuzzy interval more
effectively and further improve the prediction accuracy, a fuzzy time series prediction model based on improved wolf
pack algorithm is proposed in this paper. Firstly, the fuzzy time series is briefly introduced, then the wolf pack algorithm
is described and the chemotactic behavior and death probability are introduced into its scouting behavior to improve it.
Finally, using the improved wolf pack algorithm to divide the fuzzy interval, a new fuzzy time series prediction model is
established. The enrollments of university of Alabama is analyzed and verified as experimental data. By comparing the
forecasting results with some existing models, the proposed model has higher prediction accuracy and provides a new idea
for fuzzy time series prediction. |
