Researchers have developed TopoST, a novel approach for urban spatio-temporal foundation models that enhances knowledge sharing across diverse urban scenarios. By combining shared learning over local subgraphs with topology-conditioned node specialization, TopoST generates node-specific parameters from topological representations. This method allows for effective zero-shot generalization to unseen cities and tasks without requiring target-specific embeddings or model updates. AI
