In this paper, we investigate neural models based on graph random features. In particular, we aim to understand when over-parameterization, namely generating more features than the ones necessary to interpolate, may be beneficial for the generalization of the resulting models.

Abstract
In this paper, we investigate neural models based on graph random features. In particular, we aim to understand when over-parameterization, namely generating more features than the ones necessary to interpolate, may be beneficial for the generalization of the resulting models. Exploiting the algorithmic stability framework and based on empirical evidences from several commonly adopted graph datasets, we will shed some light on this issue.
