FRAME: Separating sampling variation from performance disparities in medical image analysis

Fair-model Reference And Mechanism Evaluation (FRAME) compares each reported difference with the difference expected from a perfectly fair model at the same subgroup counts and tests whether candidate causes of any excess over this fair-model reference change the difference when they are injected into model features.

FRAME: separating sampling variation from representational cause in medical imaging fairness

Subgroup performance differences are the standard evidence for fairness bias in medical imaging, and the usual response removes the demographic information that a model encodes. Here we introduce Fair-model Reference And Mechanism Evaluation (FRAME), a two-step framework for auditing such a claim. The first step derive...
