(a) Loss plots for original training (yellow), training with no online data augmentation (red, with error as light red), and training with online cut-paste data augmentation (blue, with error as light blue). (b) Normalized confusion matrices of FETAL-125 and OB-125 test data, for original model and model trained with online cut-paste data augmentation (three replicates shown).
