Hyperparameter Search using Genetic Algorithm for Surrogate Modeling of Geophysical Flows

Suraj Pawar, Omer San, Gary G. Yen

The computational models for geophysical flows are computationally very expensive to employ in multi-query tasks such as data assimilation, uncertainty quantification, and hence su…

On closures for reduced order models A spectrum of first-principle to machine-learned avenues

Shady E. Ahmed, Suraj Pawar, Omer San +3

For over a century, reduced order models (ROMs) have been a fundamental discipline of theoretical fluid mechanics. Early examples include Galerkin models inspired by the Orr-Sommer…
