Application of a Novel Fractional Order Grey Support Vector Regression Model to Forecast Wind Energy Consumption in China

Jiahao Cao, Liang Liu, Lizhi Yang & Shuchuan Xie · Journal of Advances in Mathematics and Computer Science · 2020

In order to achieve accurate prediction of new energy related data, a fractional grey support vector regression model based on nested cross-validation is proposed. In order to verify the superiority of the new model, China’s wind energy consumption data from 2001 to 2014 were sel...

Analysis of a Modified Gompertz Model Based on Nonlinear Least Squares Method

Lizhi Yang, Xiwang Xiang, Jiahao Cao & Yuanyuan Zhang · Journal of Advances in Mathematics and Computer Science · 2019

This paper proposes a modified Gompertz model with a constant free term based on the classical Gompertz model. Different from the three-sum method for determining the parameters of classical Gompertz model, this paper construct an optimization problem with the help of nonlinear l...
