Intro
Bias in ML models
Background: Studying Biases in Medical AI models
These Algorithms Look at X-Rays-and Somehow Detect Your Race
Solution: Retrain Model With Balance Dataset
Emory CXR dataset Balanced Training
TPR disparities persist in "balanced" datasets
Adversarial debiasing: Unlearn Biasing features
