Federated learning study compares model vs. data adaptation for medical imaging

A new study published on arXiv investigates the effectiveness of two primary approaches for improving federated learning in medical imaging: adapting the model itself or harmonizing the data. Researchers conducted a comprehensive analysis across six different medical imaging tasks, including segmentation and classification, to understand how domain heterogeneity impacts performance. Their findings indicate that the optimal strategy depends on the nature of the variation between institutions, with data harmonization being more suitable for appearance-based differences and model personalization for structural variations.
