Spatio-Temporal Gradient Enhanced Surrogate Modeling Strategies

open access: yesMathematical and Computational Applications, 2023
This research compares the performance of space-time surrogate models (STSMs) and network surrogate models (NSMs). Specifically, when the system response varies over time (or pseudo-time), the surrogates must predict the system response.
