Sparse-grids-like surrogate models enhanced with gradient information
Andrea Bressan, Sofia Imperatore, Francesca Locatelli +1
This work concerns surrogate modeling for quantities of interest (QoI) arising from parametric non-linear partial differential equations (PDEs). More specifically, we consider exte…

Artificial neural network evaluation of geometric constants for polygonal domains
Beatrice Crippa, Sofia Imperatore, Silvia Bertoluzza +1
We propose an approach based on Artificial Neural Networks (ANNs) to evaluate geometric constants relevant to the analysis and design of numerical schemes for partial differential…
