Spatio-Temporal Super-Resolution of Dynamical Systems using Physics-Informed Deep-Learning

no code implementations8 Dec 2022 Rajat Arora, Ankit Shrivastava

In this work, we propose a physics-informed deep learning-based framework to enhance the spatial and temporal resolution of coarse-scale (both in space and time) PDE solutions without requiring any HR data.
