New framework unifies graph and sheaf neural networks with richer symmetries

Researchers have introduced Order-Equivariant Neural Networks (OENNs), a novel framework that unifies graph and sheaf neural networks by leveraging richer symmetry structures. This approach generalizes existing methods and introduces new theoretical results, including characterizations of linear order-equivariant maps and universal approximation theorems for continuous order-equivariant maps, which were previously unknown for sheaf neural networks. The framework is demonstrated on graph and sheaf models, extending the known universal approximation theorems for graph neural networks to a more general setting. AI
