Stability-Shaped Deep Graph Learning

Junyou Zhu, Langzhou He, Fenying Cai وآخرون · 2026

In deep graph neural networks, increasing depth enlarges the receptive field but often leads to over-smoothing, where node representations tend to align. We develop a unified, mode-wise stability framework for deep GNN propagation that provides a principled characterization of over-smoothing. By interpreting layer dept …

WaveGSSM: Graph Wave State Space Models for Propagating Spatio-Temporal Patterns

Junyou Zhu, Fenying Cai, Ping Xiong وآخرون · 2026

Spatio-temporal graph models typically encode each snapshot with a GNN and then connect the resulting representations through a temporal module. This space-then-time design is effective, yet it does not explicitly represent how a pattern moves across the graph. We show empirically that, for a propagating process, the s …
