Hyper-differential sensitivity analysis with respect to model discrepancy: Mathematics and computation
Joseph Hart, Bart van Bloemen Waanders
Model discrepancy, defined as the difference between model predictions and reality, is ubiquitous in computational models for physical systems. It is common to derive partial diffe…
