Matrix compression along isogenic blocks
Alexander Belton, Dominique Guillot, Apoorva Khare +1
A matrix-compression algorithm is derived from a novel isogenic block decomposition for square matrices. The resulting compression and inflation operations possess strong functoria…
Gabor-type frames for signal processing on graphs
Mahya Ghandehari, Dominique Guillot, Kris Hollingsworth
In the past decade, significant progress has been made to generalize classical tools from Fourier analysis to analyze and process signals defined on networks. In this paper, we pro…
Totally positive kernels, Polya frequency functions, and their transforms
Alexander Belton, Dominique Guillot, Apoorva Khare +1
The composition operators preserving total non-negativity and total positivity for various classes of kernels are classified, following three themes. Letting a function act by post…
