New framework cuts medical image annotation effort using self-supervision

Researchers have developed a new framework called XSSR to reduce the effort needed for annotating medical images across different domains. The method uses a self-supervised approach with a Masked Autoencoder to learn from unlabeled source data, then selects representative samples from the target domain based on density, novelty, and diversity. A U-Net model is then trained on this small, selected subset, achieving performance close to using fully annotated data. AI

IMPACT Reduces annotation costs for medical AI, potentially accelerating deployment of diagnostic tools.
