基于小波去噪的改进GM(1,1)模型在高铁线下工程中的应用
Application of GM (1,1) modified model based on wavelet de-noising in high speed railway underline engineering
摘要
Abstract
The background and initial values of GM (1,1) model are improved reasonably and necessarily according to the requirements of smoothness in GM (1,1) model.Modeling data of wavelet de-noising are used to improve the precision and forecasting results of GM (1,1) model.Application cases of engineering show that there is no improvement in magnitude for the precision of simulation and prediction effect of the improved GM (1.1) model while model data are low growth index series.关键词
