Uncertainty-Aware Classifier with Physics-Based Rejection (UA-PBR): A Unified Framework for Robust Scientific Machine Learning
Deep learning classifiers deployed in scientific and industrial settings face a fundamental yet unrecognized problem: they cannot distinguish between clean in- puts and corrupted data that violates physical laws. When a medical CT scanner produces images with motion artifacts, or a reservoir sensor transmits pressure readings that violate Darcy’s law, standard neural networks process these physi- cally impossible inputs with unwarranted confidence—a silent failure mode with potentially catastrophic consequences. Existing approaches address robustness in isolation: normalization methods adapt […]
