The prediction performance of the GA-SVM model was evaluated by using a traditional SVM model with optimized grid-search-based parameters. The performance statistics of the two models are shown in Table 2. The computing time for the GA-SVM model is approximately half of that for the SVM model, but the prediction accuracy of the GA-SVM model is significantly better. These results suggest that the GA-SVM model provides improved feasibility and practicability compared to the SVM model.
