Graph Navier Stokes Networks combat oversmoothing with convection

Researchers have introduced Graph Navier Stokes Networks (GNSN), a novel architecture for Graph Neural Networks designed to overcome the oversmoothing problem. Unlike traditional diffusion-based methods, GNSN incorporates convection into graph structures by defining a dynamic velocity field for message propagation. This approach allows for a more adaptive balance between convection and diffusion, leading to improved performance on datasets with varying homophily levels. Evaluations on twelve real-world datasets show GNSN consistently outperforming existing state-of-the-art baselines in classification accuracy and effectively mitigating oversmoothing. AI
