Laplacian Matrix Learning for Smooth Graph Signal Representation

Pascal Frossard, Pierre Vandergheynst, Xiaowen Dong

The construction of a meaningful graph plays a crucial role in the emerging field of signal processing on graphs. In this paper, we address the problem of learning graph Laplacians, which is similar to learning graph topologies, such that the input data fo ...

Modeling and Controlling epidemics : a graph perspective

Philippe Sakari Rossinelli

The social and economical impact a virus has in a population is not negligible. For this reason, gaining a theoretical understanding of the behavior of a virus is of prime importance. This project is going to be divided in several parts. First, we will dis ...

New Parametric 3D Snake for Medical Segmentation of Structures with Cylindrical Topology

Michaël Unser, Daniel Andreas Schmitter

We propose a new parametric 3D snake with cylindrical topology. Its construction is based on interpolatory basis functions which facilitates user-interaction because the control points of the snake directly lie on the surface of the deformable cylinder. We ...

Energy-Efficient Inexact Speculative Adder with High Performance and Accuracy Control

Christian Enz, Vincent Frédéric Camus, Jérémy Lucien Maurice Schlachter

Inexact and approximate circuit design is a promising approach to improve performance and energy efficiency in technology-scaled and low-power digital systems. Such strategy is suitable for error-tolerant applications involving perceptive or statistical ou ...

Filming the formation and fluctuation of skyrmion domains by cryo-Lorentz transmission electron microscopy

Henrik Moodysson Rønnow, Arnaud Magrez, Marco Cantoni, Fabrizio Carbone, Jonathan White, Edoardo Baldini, Giulia Fulvia Mancini, Tatiana Latychevskaia, Ping Huang, Thierry Giamarchi, Yoshie Murooka

Magnetic skyrmions are promising candidates as information carriers in logic or storage devices thanks to their robustness, guaranteed by the topological protection, and their nanometric size. Currently, little is known about the influence of parameters su ...

Multi-Graph Learning of Spectral Graph Dictionaries

Pascal Frossard

We study the problem of learning constitutive features for the effective representation of graph signals, which can be considered as observations collected on different graph topologies. We propose to learn graph atoms and build graph dictionaries that pro ...

Optimally Efficient Multi-Party Fair Exchange and Fair Secure Multi-Party Computation

Handan Kilinç Alper

Multi-party fair exchange (MFE) and fair secure multi-party computation (fair SMPC) are under-studied fields of research, with practical importance. We examine MFE scenarios where every participant has some item, and at the end of the protocol, either ever ...

Comparative studies of electrostatic turbulence induced transport in presence of resonant magnetic perturbations in RFX-mod

Nicola Vianello

Three-dimensional non-axisymmetric magnetic fields are purposely applied to toroidally symmetric fusion plasmas in order to modify transport of heat and particle fluxes to the plasma-facing components (PFCs), and specifically to control and suppress edge l ...

Threshold phenomenon for the quintic wave equation in three dimensions

Joachim Krieger

For the critical focusing wave equation

\square u=u^5

on

\mathbb{R}^{3+1}

in the radial case, we establish the role of the “center stable” manifold

\Sigma

constructed in [18] near the ground state

(W,0)

as a threshold between blowup and scattering ...
