Reply to 'Comments on Graphon Signal Processing' [arXiv:2310.14683]
Luana Ruiz, Luiz F. O. Chamon, Alejandro Ribeiro
This technical note addresses an issue [arXiv:2310.14683] with the proof (but not the statement) of [arXiv:2003.05030, Proposition 4]. The statement of the proposition is correct,…
Graphon Signal Processing
Luana Ruiz, Luiz F. O. Chamon, Alejandro Ribeiro
Graphons are infinite-dimensional objects that represent the limit of convergent sequences of graphs as their number of nodes goes to infinity. This paper derives a theory of graph…
The Graphon Fourier Transform
Luana Ruiz, Luiz F. O. Chamon, Alejandro Ribeiro
In many network problems, graphs may change by the addition of nodes, or the same problem may need to be solved in multiple similar graphs. This generates inefficiency, as analyses…
Sparse multiresolution representations with adaptive kernels
Maria Peifer, Luiz. F. O. Chamon, Santiago Paternain +1
Reproducing kernel Hilbert spaces (RKHSs) are key elements of many non-parametric tools successfully used in signal processing, statistics, and machine learning. In this work, we a…
