SVD-Based Graph Fractional Fourier Transform on Directed Graphs and Its Application
New SVD-based graph fractional Fourier transforms are defined for directed Cartesian product graphs, extended to multiple graphs, and shown to denoise temperature data better than a prior directed graph fractional transform.
