AI fairness audits confounded by machine-generated labels, study finds

A new study published on arXiv highlights a critical issue in fairness audits for cervical-spine MRI segmentation models. Researchers found that using machine-generated 'silver' labels as a reference, instead of expensive expert-annotated 'gold' labels, can significantly skew performance and fairness assessments. While the deployed model itself was found to be demographically fair, the choice of reference label introduced bias, leading to an overestimation of performance and altering fairness verdicts, particularly concerning age.
