   We decompose the generalization gap of dermatology-AI models across skin tones, disentangling the effect of disease-distribution shift from skin-tone representation to explain why models underperform on underrepresented populations. Accepted at the MIRASOL Workshop, MICCAI 2026.

   Federated LoRA Adaptation of BiomedCLIP Across Four International Chest X-Ray Cohorts

   Sanjaya Poudel, Nirajan Kunwor, Manish Dhakal, and 2 more authors

   Abs arXiv Bib

   We study federated, parameter-efficient (LoRA) adaptation of BiomedCLIP across four international chest X-ray cohorts, evaluating aggregation strategies for robust cross-institution model adaptation without centralizing patient data. Accepted at the DeCaF Workshop, MICCAI 2026.
