Entropy Minimization without Model Collapse: Mitigating Prediction Bias in Medical Imaging

Tim Nielen, Sameer Ambekar, Johannes Kiechle +2

Entropy minimization (EM) is the dominant objective for test-time adaptation, yet its failure mode, model collapse, remains poorly understood. In this work, we show that distributi…
