“…To evaluate the predictive performance of the regression model, we choose four different criteria, including root mean square error (RMSE), mean absolute error (MAE), median absolute error (MdE), and maximum absolute error (MAxE). These criteria are commonly used indicators for assessing the predictive performance of regression models (Niu et al, 2023; Sun et al, 2023; Yang et al, 2023). The specific formulas for calculating these criteria are shown below: where N denotes the number of samples and and indicate the true value and predicted value, respectively.…”
