MAPE, MAE, R², Spearman’s correlation of SVR models with 4 different feature combinations. In Fig. 8, a, b, c, and d, respectively, represent the performance of models (including Ps and Pd) in terms of MAPE, MAE, R² and Spearman’s correlation for the feature combinations shown in Table 5. The red and blue lines represent the Ps and Pd models, respectively
