Gaussian Perturbations Prevent Oversmoothing in Recurrent GNNs

By PulseAugur Editorial · [2 sources] ·

Researchers have developed a novel method using persistent Gaussian perturbations to combat oversmoothing in recurrent graph neural networks (GNNs). This technique injects independent Gaussian noise after each propagation step, transforming the GNN into a stochastic dynamical system. The analysis shows this approach guarantees that node representations do not collapse into a low-dimensional subspace, thus preventing asymptotic oversmoothing and preserving representation diversity.
