Clinical datasets contain information about patients of different races and ages. Some groups of patients may be larger in size than others. For example, some clinical datasets contain many more white patients, which form the majority group, than Black patients, a minority group. Prediction models built on these imbalanced clinical data may provide inaccurate predictions for the minority patients. I will present our recent work on improving the prediction accuracy for minority patients in important medical applications, such as estimating the likelihood of a patient dying in an emergency room visit or surviving cancer. We have designed a bias correction technique that builds customized prediction models for different demographic groups. Our results reveal that subpopulation-specific models show better performance for minority groups. I will also discuss other important problems in achieving equitable digital health in U.S.
