Structure exploiting methods for fast uncertainty quantification in multiphase flow through heterogeneous media
Cleaves, H., Alexanderian, A., & Saad, B. (2021, September 8). COMPUTATIONAL GEOSCIENCES.
author keywords: Uncertainty quantification; Surrogate models; Dimension reduction; Multiphase flow; Sensitivity analysis; Spectral representations
TL;DR:
A computational framework for dimension reduction and surrogate modeling to accelerate uncertainty quantification in computationally intensive models with high-dimensional inputs and function-valued outputs and demonstrates the effectiveness of the proposed surrogate modeling approach with a comprehensive set of numerical experiments.

SIAM JOURNAL ON SCIENTIFIC COMPUTING, 41(6), A3524–A3551.
author keywords: global sensitivity analysis; DGSMs; functional Sobol' indices; Karhunen-Loeve expansions
TL;DR:
A framework for derivative-based global sensitivity analysis (GSA) for models with high-dimensional input parameters and functional outputs is presented and the strategy for a nonlinear ODE model of cholera epidemics and for elliptic PDEs is illustrated.
