Hyper-differential sensitivity analysis in the context of Bayesian inference applied to ice-sheet problems

William Reese, Joseph Hart, Bart van Bloemen Waanders +3

Inverse problems constrained by partial differential equations (PDEs) play a critical role in model development and calibration. In many applications, there are multiple uncertain…

Hyper-differential sensitivity analysis with respect to model discrepancy: Optimal solution updating

Joseph Hart, Bart van Bloemen Waanders

A common goal throughout science and engineering is to solve optimization problems constrained by computational models. However, in many cases a high-fidelity numerical emulation o…

Estimating and using information in inverse problems

Wolfgang Bangerth, Chris R. Johnson, Dennis K. Njeru +1

In inverse problems, one attempts to infer spatially variable functions from indirect measurements of a system. To practitioners of inverse problems, the concept of "information" i…

Sensitivity driven experimental design to facilitate control of dynamical systems

Joseph Hart, Bart van Bloemen Waanders, Lisa Hood +1

Control of nonlinear dynamical systems is a complex and multifaceted process. Essential elements of many engineering systems include high fidelity physics-based modeling, offline t…

Hyper-differential sensitivity analysis for nonlinear Bayesian inverse problems

Isaac Sunseri, Alen Alexanderian, Joseph Hart +1

We consider hyper-differential sensitivity analysis (HDSA) of nonlinear Bayesian inverse problems governed by PDEs with infinite-dimensional parameters. In previous works, HDSA has…
