Researchers have developed an episodic sampling strategy to address class imbalance in medical image segmentation, particularly for CT body composition analysis. This method, adapted from few-shot learning, constructs class-balanced batches to improve the segmentation of rare tissues. Evaluations on the SAROS dataset showed that episodic sampling outperformed random and weighted sampling under low-data conditions and matched training iteration budgets, suggesting an implicit regularization effect.
