Data Homogeneity Effect in Deep Learning-Based Prediction of Type 1 Diabetic Retinopathy

Figure 4

The images demonstrate the original (a) and superimposed Grad-CAM activation maps ((b)–(i)) of the selected diabetic retinopathy (DR) color fundus image. All models gave a true-positive prediction. There were some similarities in activation maps even in different transfer learning models trained with different datasets.
