AI research tackles CT scan bias and accuracy with KL-regularised Group DRO

Researchers have developed a new method called KL-Regularised Group Distributionally Robust Optimisation (Group DRO) to improve the fairness and robustness of AI models used for classifying volumetric CT scans. This approach addresses issues of performance disparities across different demographic groups and variations in data from various acquisition sites. The framework combines a MobileViT-XXS slice encoder with a SliceTransformer aggregator and uses the Group DRO objective to adaptively adjust for underperforming groups, preventing weight collapse with a KL penalty.
