[Retracted] Identification of Diabetic Retinopathy through Machine Learning

Table 7

Average performance of the 15 series of experiments with OPF-500 and OPF-1000, considering four classes (no DR, light DR, mod/severe, and proliferative).

OPF-500		Machine learning

With DR	Light	0	2	2	0	02/04 (50%)
	Mod/record	1	2	10	1	10/14 (71.4%)
