TL;DR: We present a novel architecture based on the Advection-Diffusion-Reaction PDE that allows greater expressiveness compared to existing models.

Abstract: Graph neural networks (GNNs) have shown remarkable success in learning representations for graph-structured data. However, GNNs still face challenges in modeling complex phenomena that involve advection. In this paper, we propose a novel GNN architecture based on Advection-Diffusion-Reaction systems, and demonstrate its efficacy on real-world spatio-temporal datasets.
