基于小波分析回归模型的大坝监测数据处理

Research on regression model based on wavelet analysis for dam monitoring

为了克服回归模型的一些缺点,将小波分析引入到回归模型里面,建立一种混合模型。本文通过介绍回归模型和小波变换,建立小波回归的混合模型,介绍建模的流程,通过小波变换来优化监测数据,再得到回归模型的估计函数。通过与回归模型的比较分析,说明这种混合模型较优的分析效果,更好的预测精度。

In order to overcome the shortcomings of the regression model, a hybrid model is established, which introduce the wavelet analysis into the regression model. After optimazation of monitoring data with wavelet transform, an estimated regression model function is obtained. Analysis result shows that this hybrid model demonstrates optimum results and better forecasting accuracy.
