Researchers have developed a new classifier called DMDSC, designed to improve open-set recognition in medical imaging datasets that suffer from extreme class imbalances. This dynamic-margin approach adjusts margins based on label frequency, applying stricter penalties and tighter feature clustering for rare pathologies. Experiments on datasets like BloodMNIST and OCTMNIST show DMDSC outperforms existing state-of-the-art methods. AI
