New analysis guarantees node separation in GNNs with Gaussian perturbations

Researchers have developed a finite-time analysis for Recurrent Graph Neural Networks (GNNs) incorporating persistent Gaussian perturbations. This analysis provides a universal lower bound of \(2\sigma^2 d\) for the expected squared distance between any two node representations at every positive time step, where \(d\) is the representation dimension and \(\sigma\) is the noise standard deviation. The findings offer dynamics-aware bounds and rigorous guarantees on node-level representation separation, complementing existing asymptotic energy analyses. AI
