Large-Scale Simulation Study of Active Learning Models for Systematic Reviews

2023

This study advocates for large-scale simulations as the gold standard for assessing active learning models for the prioritization of screening order in systematic reviews. The use of active learning to prioritize potentially relevant records in …

Why ROC-AUC Alone Is Insufficient for Highly Imbalanced Data: In-Depth Evaluation of MCC, F2-Score, H-Measure, and AUC-Based Metrics for Rare-Event Binary Classification

2025 · Preprints.org

This study re-evaluates ROC-AUC for binary classification under severe class imbalance (<3% positives). Despite widespread use, ROC-AUC can mask operationally salient differences among classifiers when false-positive and false-negative costs are asymmetric. Using three benchmarks, credit-card …
