Researchers have developed a new method for improving the reliability of classification models, particularly in scenarios with imbalanced data, such as cervical cytology. The study focused on the Mendeley LBC dataset, using its native four-class Bethesda taxonomy. By employing post-hoc temperature scaling for calibration, the models demonstrated a significant reduction in calibration errors and Brier scores, while discrimination metrics remained largely unaffected. The findings suggest that proper calibration is more critical for reliability than ensemble size in this context, though the dataset's modest size warrants consideration. AI
