A new study published on arXiv investigates the effectiveness of foundation models (FMs) in detecting Brugada syndrome, a rare cardiac condition. The research found that while FMs can improve optimization for high-capacity architectures, they do not inherently provide transferable clinical knowledge for rare diseases. In zero-shot cross-site transfer scenarios, FM-based pipelines performed similarly to supervised baselines, suggesting that model architecture and data-domain alignment are more critical than pre-training alone for capturing clinically meaningful representations.

IMPACT Challenges the assumption that large-scale pre-training inherently encodes clinically meaningful representations for rare diseases.
