参数最优化的GM(1,1)模型
GM(1,1) model with optimal parameters
摘要
Abstract
The precision of GM(1,1) model is decided by the parameters a and u ,while the parameters a and udepend on the selection of original condition and the conformation of background values.Optimization factor is introduced into the conformation of background values, and the new GM(1,1) model with optimal parameters is obtained by choosing the optimal original condition and optimization factor. Numerical tests indicate that the GM(1,1) model with optimal parameters has higher precision than the traditional GM(1,1) model and the new GM(1,1) model in the literature.关键词
