Equivariant Subgraph Aggregation Networks

Bevilacqua, Beatrice, Frasca, Fabrizio, Lim, Derek et al.

Understand

Message-passing neural networks (MPNNs) are the leading architecture for deep learning on graph-structured data, in large part due to their simplicity and scalability.

  • Unfortunately, it was shown that these architectures are limited in their expressive power.
  • This paper proposes a novel framework called Equivariant Subgraph Aggregation Networks (ESAN) to address this issue.
  • Our main observation is that while two graphs may not be distinguishable by an MPNN, they often contain distinguishable subgraphs.
