Knowing When Not to Predict: Self Supervised Learning and Abstention for Safer DR Screening

Muskaan Chopra, Lorenz Sparrenberg, Jan H. Terheyden +1

Self-supervised learning (SSL) is now a standard way to pretrain medical image models, but performance is still mostly judged by downstream accuracy. For safety-critical screening…
