Average absolute errors on the mean (top) and maximum doses (bottom) for the predictions (AB and Mask models) versus the clinical dose (D_C) of all six experimental groups on the test set for relevant targets and organs. The black lines on top of the bars represent the standard deviation associated with each ROI. Lung_C means contralateral lung, and Lung_I means ipsilateral lung. Considering the abysmal statistical result for PTV on the D_mean of the MaskO method, Mask’s is used instead
