Note: for Model 5, Model 6, Model 7, or Model 8, the total number of samples used for the training set was 60 (20 × 3), and the total number of samples used for the testing set was 30 (10 × 3). For Model 9, the total number of samples used for the training set was 240 (80 × 3), and the total number of samples used for the testing set was 120 (40 × 3).
