Model 2	CYR32	0 w/cm^2	20	20	10	10
		150 w/cm^2	20	20	10	10
		200 w/cm^2	20	20	10	10
		250 w/cm^2	20	20	10	10
Model 3	CYR33	0 w/cm^2	20	19	10	10
		150 w/cm^2	20	20	10	8
		200 w/cm^2	20	19	10	7
		250 w/cm^2	20	20	10	10
Model 4	Mixed physiological races with the three races	0 w/cm^2	60	60	30	30
		150 w/cm^2	60	60	30	30
		200 w/cm^2	60	60	30	26
		250 w/cm^2	60	60	30	29

Note: for Model 1, Model 2, or Model 3, the total number of samples used for the training set was 80 (20 × 4), and the total number of samples used for the testing set was 40 (10 × 4). For Model 4, the total number of samples used for the training set was 240 (60 × 4), and the total number of samples used for the testing set was 120 (30 × 4).
