Researchers have developed a new method to improve the calibration of medical image segmentation models, particularly when multiple expert annotations show significant disagreement. The approach reformulates multi-rater supervision as an ordinal learning problem, treating voxel-wise annotator agreement as an ordered target. This allows model confidence to better reflect the empirical variability in training data, leading to improved calibration without sacrificing segmentation accuracy. AI
