An Empirical Study of Machine Learning Robustness and Scalability for Imbalanced Tabular Clinical Data in Emergency and Critical Care
arXiv:2512.21602v3 Announce Type: replace Abstract: Every year, millions of patients pass through emergency departments and intensive care units, where clinicians must make high-stakes decisions under time pressure and uncertainty. Machine learning could support prediction of deterioration, triage, and rare critical outcomes, but clinical data are often severely imbalanced, biasing models toward majority classes and reducing predictive performance. Developing robust and efficient models for imbalanced clinical tabular data therefore remains an important challenge. We evaluated six model famili
The increasing availability of clinical data and advancements in machine learning techniques make robust model development applicable now, especially given the ongoing strain on healthcare systems.
Improving AI's ability to handle imbalanced clinical data is crucial for its reliable deployment in high-stakes medical environments, directly impacting patient outcomes and healthcare efficiency.
This research provides empirical evidence and methods for building more reliable machine learning models for critical care, potentially accelerating the adoption of AI in clinical decision support.
