New framework detects demographic bias in medical imaging AI

Researchers have developed a new statistical framework to identify and quantify biases in machine learning models used for medical imaging. This method utilizes counterfactual invariance, assessing how model predictions change when hypothetical demographic attributes are altered. The approach combines conditional latent diffusion models with statistical hypothesis testing, enabling bias detection without needing direct counterfactual data. Experiments on synthetic and real-world datasets like CheXpert and MIMIC-CXR demonstrate its effectiveness in ensuring equitable generalization across demographic groups, contributing to AI safety in healthcare.
