HoloNets: Spectral Convolutions do extend to Directed Graphs

no code implementations3 Oct 2023 Christian Koke, Daniel Cremers

Within the graph learning community, conventional wisdom dictates that spectral convolutional networks may only be deployed on undirected graphs: Only there could the existence of a well-defined graph Fourier transform be guaranteed, so that information may be translated between spatial- and spectral domains.

Limitless stability for Graph Convolutional Networks

no code implementations26 Jan 2023 Christian Koke

Stability to node-level perturbations is related to an 'adequate (spectral) covering' property of the filters in each layer.
