WELDE: A Weighted Ensemble Loss with Diversity Enhancement for Imbalanced Object Detection in Medical Imaging

2026-03-24

Abstract excerpt

<title>Abstract</title> <p> Class imbalance in medical imaging datasets remains a key challenge for reliable object detection, particularly when rare yet clinically significant pathologies coexist with prevalent findings. In spinal MRI, common conditions such as Normal Intervertebral Disc (IVD) may constitute over 45% of annotated objects, whereas findings like Spondylolisthesis account for fewer than 2% of inst...
