Researchers have developed KAISEN, a novel five-phase audit pipeline designed to improve the reproducibility and reliability of fairness assessments in clinical risk models. The pipeline addresses subgroup stratification, disparity measurement, mechanism diagnostics, post-hoc mitigation, and drift monitoring. Evaluations on a synthetic benchmark revealed that per-group threshold optimization significantly reduces disparities, while group-wise Platt scaling showed limited effectiveness. The mechanism diagnostic component proved effective in controlled scenarios but struggled with model-driven cases under proxy misspecification. AI
