Nonsmooth convex optimization to estimate the Covid-19 reproduction number space-time evolution with robustness against low quality data
Barbara Pascal, Patrice Abry, Nelly Pustelnik +3
Daily pandemic surveillance, often achieved through the estimation of the reproduction number, constitutes a critical challenge for national health authorities to design countermea…
Exploring and comparing temporal clustering methods
Jordan Cambe, Sebastian Grauwin, Patrick Flandrin +1
Description of temporal networks and detection of dynamic communities have been hot topics of research for the last decade. However, no consensual answers to these challenges have…
Revealing evolutions in dynamical networks
Matteo Morini, Patrick Flandrin, Eric Fleury +2
The description of large temporal graphs requires effective methods giving an appropriate mesoscopic partition. Many approaches exist today to detect communities in static graphs.…
When interpolation-induced reflection artifact meets time-frequency analysis
Yu-Ting Lin, Patrick Flandrin, Hau-tieng Wu
While extracting the temporal dynamical features based on the time-frequency analyses, like the reassignment and synchrosqueezing transform, attracts more and more interest in bio-…
Duality between Temporal Networks and Signals: Extraction of the Temporal Network Structures
Ronan Hamon, Pierre Borgnat, Patrick Flandrin +1
We develop a framework to track the structure of temporal networks with a signal processing approach. The method is based on the duality between networks and signals using a multid…
From graphs to signals and back: Identification of network structures using spectral analysis
Ronan Hamon, Pierre Borgnat, Patrick Flandrin +1
Many systems comprising entities in interactions can be represented as graphs, whose structure gives significant insights about how these systems work. Network theory has undergone…
Discovering the structure of complex networks by minimizing cyclic bandwidth sum
Ronan Hamon, Pierre Borgnat, Patrick Flandrin +1
Getting a labeling of vertices close to the structure of the graph has been proved to be of interest in many applications e.g., to follow smooth signals indexed by the vertices of…
2-D Prony-Huang Transform: A New Tool for 2-D Spectral Analysis
Jérémy Schmitt, Nelly Pustelnik, Pierre Borgnat +2
This work proposes an extension of the 1-D Hilbert Huang transform for the analysis of images. The proposed method consists in (i) adaptively decomposing an image into oscillating…
French Roadmap for complex Systems 2008-2009
Paul Bourgine, David Chavalarias, Edith Perrier +78
This second issue of the French Complex Systems Roadmap is the outcome of the Entretiens de Cargese 2008, an interdisciplinary brainstorming session organized over one week in 2008…
