Signal processing on large networks with group symmetries
Kathryn Beck, Mahya Ghandehari, Jeannette Janssen +1
Current methods of graph signal processing rely heavily on the specific structure of the underlying network: the shift operator and the graph Fourier transform are both derived dir…

Frames for signal processing on Cayley graphs
Kathryn Beck, Mahya Ghandehari, Skyler Hudson +1
The spectral decomposition of graph adjacency matrices is an essential ingredient in the design of graph signal processing (GSP) techniques. When the adjacency matrix has multi-dim…

Frames for Graph Signals on the Symmetric Group: A Representation Theoretic Approach
Kathryn Beck, Mahya Ghandehari
An important problem in the field of graph signal processing is developing appropriate overcomplete dictionaries for signals defined on different families of graphs. The Cayley gra…
