A Hybrid Deep Neural Operator/Finite Element Method for Ice-Sheet Modeling

no code implementations26 Jan 2023 Qizhi He, Mauro Perego, Amanda A. Howard, George Em Karniadakis, Panos Stinis

One of the most challenging and consequential problems in climate modeling is to provide probabilistic projections of sea level rise.

Multifidelity Deep Operator Networks For Data-Driven and Physics-Informed Problems

no code implementations19 Apr 2022 Amanda A. Howard, Mauro Perego, George E. Karniadakis, Panos Stinis

We demonstrate the new multi-fidelity training in diverse examples, including modeling of the ice-sheet dynamics of the Humboldt glacier, Greenland, using two different fidelity models and also using the same physical model at two different resolutions.

Robust Training and Initialization of Deep Neural Networks: An Adaptive Basis Viewpoint

no code implementations10 Dec 2019 Eric C. Cyr, Mamikon A. Gulian, Ravi G. Patel, Mauro Perego, Nathaniel A. Trask

Motivated by the gap between theoretical optimal approximation rates of deep neural networks (DNNs) and the accuracy realized in practice, we seek to improve the training of DNNs.
