3.1 Model optimization
Through different combinations of feature classes and regularized multipliers, the best model parameter is selected as among all combinations (feature classes: linear, product, threshold, and hinge; regularized multipliers=2), the parameters of all candidate models are shown in Table S3.
In the simulation of the current and future distribution of B. gargarizans , the AUC value indicated that the simulation results of all models reached an excellent level (0.9202≤ Training AUC≤0.9306, 0.9001≤ Test AUC≤0.9165, SD≤0.014), all AUC values are presented in Table S4
