Graph Neural Networks with Random Features Show Universality

By PulseAugur Editorial · [2 sources] ·

A new research paper explores the capabilities of message-passing graph neural networks (GNNs) when augmented with random node features. The study establishes a theoretical universality result for permutation-equivariant neural networks (PENNs), a class of GNNs that includes many popular architectures. The findings indicate that PENNs with partially randomized node features can effectively approximate a wide range of functions on directed graphs of a fixed size. Additionally, the research provides bounds on approximation rates for continuously differentiable functions, linking the complexity of the network's feedforward components to the accuracy of the approximation.
