Model Error Embedding with Orthogonal Gaussian Processes
Mridula Kuppa, Khachik Sargsyan, Marco Panesi +1
Computational models of complex physical systems often rely on simplifying assumptions which inevitably introduce model error, with consequent predictive errors. Given data on mode…

Weight-Parameterization in Continuous Time Deep Neural Networks for Surrogate Modeling
Haley Rosso, Lars Ruthotto, Khachik Sargsyan
Continuous-time deep learning models, such as neural ordinary differential equations (ODEs), offer a promising framework for surrogate modeling of complex physical systems. A centr…

Improving the quasi-biennial oscillation via a surrogate-accelerated multi-objective optimization
Luis Damiano, Walter M. Hannah, Chih-Chieh Chen +4
Simulating the QBO remains a formidable challenge partly due to uncertainties in representing convectively generated gravity waves. We develop an end-to-end uncertainty quantificat…
