Active-Learning-Driven Surrogate Modeling for Efficient Simulation of Parametric Nonlinear Systems

no code implementations9 Jun 2023 Harshit Kapadia, Lihong Feng, Peter Benner

When repeated evaluations for varying parameter configurations of a high-fidelity physical model are required, surrogate modeling techniques based on model order reduction are desired.

A Training Set Subsampling Strategy for the Reduced Basis Method

no code implementations10 Mar 2021 Sridhar Chellappa, Lihong Feng, Peter Benner

Then, for the available low-fidelity snapshots of the output variable, we apply the pivoted QR decomposition or the discrete empirical interpolation method to identify a set of sparse sampling locations in the parameter domain.
