Table 4.
Diabetic retinopathy (DR) and Chest X-ray (CXR) mean and standard deviation test set accuracies across 10 runs for the various label distribution splits with centrally hosted and distributed training. Bold entries represent optimizations that resulted in significantly better performance than performance of cyclical weight transfer without optimizations for the same split
