The Underappreciated Power of Vision Models for Graph Structural Understanding

2025-10-27

AI Summary

This work identifies inherent limitations of Graph Neural Networks (GNNs) in global structural reasoning—including prototype identification, symmetry detection, connectivity assessment, and critical node localization—as well as in scale-invariant inference. To address these gaps, we introduce GraphAbstract, the first benchmark explicitly designed for global topological awareness, and propose a novel paradigm for graph structural understanding grounded in pretrained vision models: graphs are encoded into structure-preserving visual representations, enabling zero-shot or few-shot visual transfer for cross-scale generalization. Empirical results demonstrate that vision models significantly outperform state-of-the-art GNNs across multiple global property recognition tasks, validating their capacity to capture long-range dependencies and holistic topology without explicit message passing. This approach offers a scalable, robust, and interpretable alternative to conventional graph learning.

Abstract

Graph Neural Networks operate through bottom-up message-passing, fundamentally differing from human visual perception, which intuitively captures global structures first. We investigate the underappreciated potential of vision models for graph understanding, finding they achieve performance comparable to GNNs on established benchmarks while exhibiting distinctly different learning patterns. These divergent behaviors, combined with limitations of existing benchmarks that conflate domain features with topological understanding, motivate our introduction of GraphAbstract. This benchmark evaluates models' ability to perceive global graph properties as humans do: recognizing organizational archetypes, detecting symmetry, sensing connectivity strength, and identifying critical elements. Our results reveal that vision models significantly outperform GNNs on tasks requiring holistic structural understanding and maintain generalizability across varying graph scales, while GNNs struggle with global pattern abstraction and degrade with increasing graph size. This work demonstrates that vision models possess remarkable yet underutilized capabilities for graph structural understanding, particularly for problems requiring global topological awareness and scale-invariant reasoning. These findings open new avenues to leverage this underappreciated potential for developing more effective graph foundation models for tasks dominated by holistic pattern recognition.
