arXiv:2606.01283v1 Announce Type: new Abstract: Modeling spatial dependencies is central to spatiotemporal data analysis using Graph Neural Networks (GNNs). Traditional methods rely on distance-based kernels with predefined parameters, which restricts model capacity. Although generic adaptive mechanisms (e.g., Graph Attention Networks) offer flexibility, they often fail to capture the underlying geometric structure, performing worse than distance-based models in data-sparse scenarios. Addressing this, we revisit the kernel parameterization problem and theoretically prove that misspecified kern
The continuous evolution of GNNs in spatiotemporal data analysis pushes for more refined strategies to handle geometric structures and data scarcity, driving innovation in kernel parameterization.
Improving spatiotemporal GNNs with adaptive kernel parameters is crucial for more accurate and robust AI models in critical applications such as urban planning, climate modeling, and autonomous systems.
The ability of GNNs to model complex spatial dependencies, especially in data-sparse environments, will improve through more adaptive and theoretically grounded kernel parameterization.
