A new study published on arXiv evaluates the complete pipeline for unsupervised domain adaptation (UDA) in medical imaging, focusing on the challenge of selecting the best model without access to labeled target data. The research analyzed over 80,000 trained models across eleven clinical scenarios, ten UDA algorithms, and thirteen label-free selection methods. Findings indicate that while capable adapted models often exist, reliably identifying them is difficult, with current selection methods leaving a significant performance gap. Strategies like ensembling and using a small labeled budget can narrow this gap but do not fully close it, suggesting that improvements in the model selection step are crucial for bringing UDA closer to clinical deployment.
