Episodic sampling improves medical image segmentation in low-data scenarios

By PulseAugur Editorial · [2 sources] ·

Researchers have developed an episodic sampling method to improve class-balanced batch construction for medical image segmentation, particularly in scenarios with imbalanced datasets. This technique, adapted from few-shot learning, was evaluated on CT body composition segmentation and showed superior performance over random and weighted sampling under low-data conditions. The study highlights the importance of considering training iteration budgets when comparing sampling strategies, suggesting episodic sampling offers a low-cost, model-agnostic approach for addressing class imbalance in medical imaging.

    Disentangling Sampling from Training Budget in Class-Imbalanced CT Body Composition Segmentation

    Episodic sampling from few-shot learning improves class-balanced batch construction in medical image segmentation, outperforming random and weighted sampling under low-data conditions due to reduced overfitting and extended training iterations.
