Physical systems are at the core of many scientific and engineering efforts and the scientific field has explored many of them in great detail. Nonetheless, machine learning efforts to model these systems have been quite separated from the partial differential equations commonly used to describe their dynamics and the numerical methods that are used to solve these equations.
In this talk, I will describe a new model for spatio-temporal forecasting that we have introduced in joint work with Stephan Günnemann. The proposed graph neural network is closely related to the finite element method and can be equipped with intrinsic knowledge of partial differential equations. I will explain the derivation of the model and present empirical results from our paper.
