| Abstract: | Using non-equidistant GM (1,1) model, based on a linear interpolation GM (1,1) and neural network-based GM (1, 1) model for the building settlement observation data analysis and forecasting, and the modeling process was described by Matlab pro-gramming language.We can know the advantages and disadvantages of the three methods based on predictions of models;it has some significance for the actual project data processing method selection. |
