Calibration and Uncertainty Quantification for Machine Learning Models in Imbalanced HIV Viral Load Prediction: A Reliability-Based Evaluation

Machine learning (ML) models for HIV prediction are often evaluated using discrimination metrics (e.g., AUC) while neglecting calibration and predictive uncertainty, a critical gap in imbalanced clinical datasets where inaccurate probability estimates can harm decision-making. This study evaluated the calibration, unce...

SHAP-Based Explainable Machine Learning for Predicting Loan Default among Women-Owned Microenterprises in Kenya

Background: Access to credit remains a major challenge for women-owned microenterprises in sub-Saharan Africa, yet existing loan default prediction models often lack transparency and interpretability. This study aimed to develop and evaluate a SHAP-based explainable machine learning framework for predicting loan defaul...
