Entropy Minimization without Model Collapse: Mitigating Prediction Bias in Medical Imaging
Publisher summary· verbatim
arXiv:2606.02339v1 Announce Type: new Abstract: 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 distribution shifts can cause feature clusters corresponding to distinct classes i
