arXiv:2606.21333v2 Announce Type: replace Abstract: Graph Neural Networks (GNNs) have emerged as a powerful paradigm for learning on graph-structured data by iteratively propagating and aggregating information across edges. However, conventional message passing schemes often suffer from over-squashing, whereby exponentially large neighborhoods are compressed into fixed-dimensional embeddings, impeding effective long-range dependency learning. In this work, we introduce Ramanujan Propagation, a graph rewiring strategy that leverages Ramanujan graphs to alleviate topological bottlenecks in GNNs.
The continuous evolution of AI, particularly in graph neural networks, necessitates novel approaches to overcome fundamental architectural limitations like over-squashing.
Improving the efficiency and effectiveness of GNNs in handling complex, large-scale data structures is crucial for advancing AI capabilities, especially in tasks requiring long-range dependency learning.
This research introduces a new graph rewiring strategy, 'Ramanujan Propagation,' potentially leading to more powerful and scalable GNN architectures.
