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}…
Privacy in trajectory micro-data publishing : a survey
Marco Fiore, Panagiota Katsikouli, Elli Zavou +7
We survey the literature on the privacy of trajectory micro-data, i.e., spatiotemporal information about the mobility of individuals, whose collection is becoming increasingly simp…
Variants of a-T-menability for actions on non-commutative Lp spaces
Baptiste Olivier
We investigate various characterizations of the Haagerup property (H) for a second countable locally compact group G, in terms of orthogonal representations of G on non-commutative…
Property (T) with respect to non-commutative Lp-spaces
Baptiste Olivier
We show that a group with Kazhdan's property has property for the Haagerup non-commutative -space associated with a von Neumann algebra $\ma…
