WebNov 25, 2024 · Abstract. Typically network structures are represented by one of three different graph shift operator matrices: the adjacency matrix and unnormalised and normalised Laplacian matrices. To enable a sensible comparison of their spectral (eigenvalue) properties, an affine transform is first applied to one of them, which … Webtime-varying graph signals, and second we prove its stability. Specifically, we provide a general definition of convolutions for any arbitrary shift operator and define a space-time shift operator (STSO) as the linear composition of the graph shift operator (GSO) and time-shift operator (TSO).
