  • Publication number: 20220261440
    Abstract: A conversion unit converts directions of edges between vertices in a graph to arguments on a complex plane. A generation unit generates a Hermitian matrix that represents a relationship between vertices in the graph by using the arguments converted by the conversion unit. A calculation unit calculates eigenvectors of the Hermitian matrix generated by the generation unit. A signal processing unit performs graph signal processing such as graph Fourier transform taking the eigenvectors calculated by the calculation unit to be a Fourier basis for a graph Laplacian.
