Synthetic Datasets for Machine Learning on Spatio-Temporal Graphs using PDEs

Jost Arndt, Utku Isil, Michael Detzel +2

Many physical processes can be expressed through partial differential equations (PDEs). Real-world measurements of such processes are often collected at irregularly distributed poi…
