Multi-Algorithm Optimization of Explanation Stability in Ensemble Learning for Human Capital Attrition Risk Prediction
Attrition models are tuned for discrimination, but the decision they support is a ranking of retention drivers, and nothing requires that ranking to survive retraining. We treat its reproducibility as an objective: hyperparameter optimization for an ensemble of gradient-boosted and bagged learners becomes a bi-objectiv...
