Small Graph Is All You Need: DeepStateGNN for Scalable Traffic Forecasting

no code implementations20 Feb 2025 Yannick Wölker, Arash Hajisafi, Cyrus Shahabi, Matthias Renz

Unlike typical GNN methods that treat each traffic sensor as an individual graph node, DeepStateGNN clusters sensors into higher-level graph nodes, dubbed Deep State Nodes, based on various similarity criteria, resulting in a fixed number of nodes in a Deep State graph.
