基于 SVM-ARIMA的大坝变形预测模型
SVM-ARIMA Forecasting Model for Dam Deformation
摘要
Abstract
The monitoring data of the dam deformation is a nonlinear and non-stationary time series. After the introduction of kernel function,sup-port vector machine can solve the nonlinear problem effectively,so support vector machine was used to predict the dam deformation. In order to im-prove the prediction accuracy,ARIMA model was used to further analysis the residual series,therefore,SVM-ARIMA combination model was es-tablished to predict the dam deformation. The time series of dam deformation was divided into two parts:the trend term and the error term,they were predicted by SVM and ARIMA models respectively,the sum of the two parts was the final predicted value. At last,there was a comparison be-tween the measured data and the predicted one combined with a project. The result indicates that the accuracy of the SVM-ARIMA model is high, completely meeting the project needs.关键词
