Gasper: GrAph Signal ProcEssing in R
Basile de Loynes, Fabien Navarro, Baptiste Olivier
We present a short tutorial on to the use of the R gasper package. Gasper is a package dedicated to signal processing on graphs. It also provides an interface to the SuiteSparse Ma…
Data-driven Thresholding in Denoising with Spectral Graph Wavelet Transform
Basile de Loynes, Fabien Navarro, Baptiste Olivier
This paper is devoted to adaptive signal denoising in the context of Graph Signal Processing (GSP) using Spectral Graph Wavelet Transform (SGWT). This issue is addressed \emph{via}…
A note on the Martin boundary of the simple random walk on an example of directed graph
Basile de Loynes
In this note, we study the Martin boundary of the simple random walk on an example of directed graph. More precisely, the Martin boundary is shown to be trivial, i.e. there is no n…
Random walk on a directed graph and Martin boundary
Basile de Loynes
The Martin boundary associated with the simple random walk on an example of partially oriented lattice is shown to be trivial by computing fine estimates of the Green kernel.
