Over-squashing as Transport Congestion: A Sandpile Dynamics Perspective

A differentiable Sandpile Stabilization Layer (SSL) and congestion-aware objectives designed to redistribute excess load and manage stabilization costs are proposed and Experiments on long-range benchmarks show that targeting sandpile-identified bottlenecks mitigates representation collapse and improves over standard b...

Over-squashing as Transport Congestion: A Sandpile Dynamics Perspective

Message-passing graph neural networks (MP-GNNs) are widely used for learning on relational data. However, their performance drops on tasks requiring long-range interactions due to over-squashing, where exponential information compression overwhelms fixed-width embeddings. While existing analyses often attribute this to...
