Large Graph Signal Denoising with Application to Differential Privacy
Elie Chedemail, Basile de Loynes, Fabien Navarro +1
Over the last decade, signal processing on graphs has become a very active area of research. Specifically, the number of applications, for instance in statistical or deep learning,…
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…
Localized Fourier Analysis for Graph Signal Processing
Basile de Loynes, Fabien Navarro, Baptiste Olivier
We propose a new point of view in the study of Fourier analysis on graphs, taking advantage of localization in the Fourier domain. For a signal on vertices of a weighted graph…
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}…
