A Stochastic Majorize-Minimize Subspace Algorithm for Online Penalized Least Squares Estimation
Chouzenoux Emilie, Pesquet Jean-Christophe
Stochastic approximation techniques play an important role in solving many problems encountered in machine learning or adaptive signal processing. In these contexts, the statistics…
Water transfer and crack regimes in nano-colloidal gels
J Thiery, Stéphane Rodts, E Keita +5
Direct observations of the surface and shape of model nano-colloidal gels associated with measurements of the spatial distribution of water content during drying show that air star…
Pattern matching in -avoiding permutations
Both Emerite Neou, Romeo Rizzi, Stéphane Vialette
Given permutations and with , the \emph{pattern matching} problem is to decide whether matches as an order-isomorphic subsequence. We give a line…
Effective Invariant Theory of Permutation Groups using Representation Theory
Nicolas Borie
Using the theory of representations of the symmetric group, we propose an algorithm to compute the invariant ring of a permutation group. Our approach have the goal to reduce the a…
Superpixel Convolutional Networks using Bilateral Inceptions
Raghudeep Gadde, Varun Jampani, Martin Kiefel +2
In this paper we propose a CNN architecture for semantic image segmentation. We introduce a new 'bilateral inception' module that can be inserted in existing CNN architectures and…
Detecting global bridges in networks
Pablo Jensen, Matteo Morini, Marton Karsai +6
The identification of nodes occupying important positions in a network structure is crucial for the understanding of the associated real-world system. Usually, betweenness centrali…
A Survey on the Eigenvalues Local Behavior of Large Complex Correlated Wishart Matrices
Walid Hachem, Adrien Hardy, Jamal Najim
The aim of this note is to provide a pedagogical survey of the recent works by the authors ( arXiv:1409.7548 and arXiv:1507.06013) concerning the local behavior of the eigenvalues…
Coupling a reactive potential with a harmonic approximation for atomistic simulations of material failure
Ignacio Tejada, Laurent Brochard, Tony Lelievre +3
Molecular dynamics (MD) simulations involving reactive potentials can be used to model material failure. The empirical potentials which are used in such simulations are able to ada…
A semi-decentralized control strategy for urban traffic
Nadir Farhi, Cyril Nguyen Van Phu, Mouna Amir +2
We present in this article a semi-decentralized approach for urban traffic control, based on the TUC (Traffic responsive Urban Control) strategy. We assume that the control is cent…
Variants of the Empirical Interpolation Method: symmetric formulation, choice of norms and rectangular extension
Fabien Casenave, Alexandre Ern, Tony Lelièvre
The Empirical Interpolation Method (EIM) is a greedy procedure that constructs approximate representations of two-variable functions in separated form. In its classical presentatio…
Transient thermal mixed boundary value problems in the half-space
William J. Parnell, Vu-Hieu Nguyen, Raphael Assier +2
The Wiener-Hopf and Cagniard-de Hoop techniques are employed in order to solve a range of transient thermal mixed boundary value problems on the half-space. The thermal field is de…
A mathematical analysis of the GW0 method for computing electronic excited energies of molecules
Eric Cancès, David Gontier, Gabriel Stoltz
This paper analyses the GW method for finite electronic systems. In a first step, we provide a mathematical framework for the usual one-body operators that appear naturally in many…
Convergence in of weak solutions to perturbed doubly degenerate parabolic equations
Jérôme Droniou, Robert Eymard, Kyle S. Talbot
We study the behaviour of solutions to a class of nonlinear degenerate parabolic problems when the data are perturbed. The class includes the Richards equation, Stefan problem and…
Explicit vector spherical harmonics on the 3-sphere
J. Ben Achour, E. Huguet, J. Queva +1
We build a family of explicit one-forms on which are shown to form a complete set of eigenmodes for the Laplace-de Rahm operator.
A Survey of Stochastic Simulation and Optimization Methods in Signal Processing
Marcelo Pereyra, Philip Schniter, Emilie Chouzenoux +4
Modern signal processing (SP) methods rely very heavily on probability and statistics to solve challenging SP problems. SP methods are now expected to deal with ever more complex m…
Bernstein type inequality for a class of dependent random matrices
Marwa Banna, Florence Merlevède, Pierre Youssef
In this paper we obtain a Bernstein type inequality for the sum of self-adjoint centered and geometrically absolutely regular random matrices with bounded largest eigenvalue. This…
Flow of wet granular materials: a numerical study
Saeed Khamseh, Jean-Noël Roux, François Chevoir
We simulate dense assemblies of frictional spherical grains in steady shear flow under controlled normal stress in the presence of a small amount of an interstitial liquid, whi…
RNF: a general framework to evaluate NGS read mappers
Karel Břinda, Valentina Boeva, Gregory Kucherov
Aligning reads to a reference sequence is a fundamental step in numerous bioinformatics pipelines. As a consequence, the sensitivity and precision of the mapping tool, applied with…
On estimation of the diagonal elements of a sparse precision matrix
Samuel Balmand, Arnak S. Dalalyan
In this paper, we present several estimators of the diagonal elements of the inverse of the covariance matrix, called precision matrix, of a sample of iid random vectors. The focus…
Hyper Temporal Networks
Carlo Comin, Roberto Posenato, Romeo Rizzi
Simple Temporal Networks (STNs) provide a powerful and general tool for representing conjunctions of maximum delay constraints over ordered pairs of temporal variables. In this pap…
Performance analysis of an improved MUSIC DoA estimator
Pascal Vallet, Xavier Mestre, Philippe Loubaton
This paper adresses the statistical performance of subspace DoA estimation using a sensor array, in the asymptotic regime where the number of samples and sensors both converge to i…
Locating a Tree in a Phylogenetic Network in Quadratic Time
Philippe Gambette, Andreas D. M. Gunawan, Anthony Labarre +2
A fundamental problem in the study of phylogenetic networks is to determine whether or not a given phylogenetic network contains a given phylogenetic tree. We develop a quadratic-t…
