AUCs of models with and without proposed augmentation in detecting demographic attributes in brain MRI.
| Augmentation | Age (0–75 vs. 75+) | Sex (Female vs. Male) |
|---|---|---|
| w/o | 0.655 [0.575–0.735] | 0.856 [0.800–0.912] |
| w/ | 0.535 [0.448–0.622] | 0.555 [0.468–0.641] |
Lower values indicate a weaker ability to recognise age or sex based on brain MRI images. The model trained using augmented images is hard to recognise demographic attributes from brain MRI. The minimum values are highlighted in bold.
