E. P. Thompson, une vie de combat
2015
National audience; Grand historien de la classe ouvrière anglaise, figure intellectuelle majeure des débats sur le marxisme dans les années 1960-1970, militant antinucléaire à l’origine d’une critique écologiste du capitalisme : tels furent les visages multiples d’Edward Palmer Thompson, dont l’œuvre continue d’imprégner en profondeur l’ensemble des sciences sociales.

Comparaison de différents plans de sondage et construction de bandes de confiance pour l'estimation de la moyenne de données fonctionnelles : une ill…
2012
Accepté pour publication dans Survey Methodology/Techniques d'Enquêtes.; Lorsque les variables étudiées sont fonctionnelles et que les capacités de stockage sont limitées ou que les coûts de transmission sont élevés, les sondages, qui permettent de sélectionner une partie des observations de la population, sont des alternatives intéressantes aux techniques de compression du signal. Notre étude est motivée, dans ce contexte fonctionnel, par l'estimation de la courbe de charge électrique moyenne sur une période d'une semaine. Nous comparons différentes stratégies d'estimation permettant de prendre en compte une information auxiliaire telle que la consommation totale de la période précédente. …

Equivariant, Almost-Arborescent Representations of Open simply-Connected 3-Manifolds; A Finiteness result
2004
When one extends the (almost) collapsible pseudo-spine representation theorem for homotopy 3-spheres [Po3] to open simply connected 3-manifolds V 3,new phenomena appear: at the source of the representation, the set of double points is, generally speaking, no longer closed. We show that at the cost of replacing V3 by Vh3 = {V3 with very many holes }, we can always find representations X2 →f V3 with X2 locally finite and almost-arborescent, with Ψ (f) = Φ(f), with the open regular neighbourhood (the only one which is well-defined here) Nbd(f X2) = Vh3 and such that on any precompact tight transversal to the set of double lines, we have only FINITELY many limit points (of the set of double poi…
Estimation of forest stand characteristics using individual tree detection, stochastic geometry and a sequential spatial point process model
2022
Airborne Laser Scanning (ALS) results in point-wise measurements of canopy height, which can further be used for Individual Tree Detection (ITD). However, ITD cannot find all trees because small trees can hide below larger tree crowns. Here we discuss methods where the plot totals and means of tree-level characteristics are estimated in such context. The starting point is a previously presented Horvitz–Thompson-like (HT-like) estimator, where the detectability is based on the larger tree crowns and a tuning parameter that models the detection condition. We propose a new method which is based on modeling the spatial pattern of hidden tree locations using a sequential spatial point process mo…

Arm Space Decomposition as a Strategy for Tackling Large Scale Multi-armed Bandit Problems
2013
Recent multi-armed bandit based optimization schemes provide near-optimal balancing of arm exploration against arm exploitation, allowing the optimal arm to be identified with probability arbitrarily close to unity. However, the convergence speed drops dramatically as the number of bandit arms grows large, simply because singling out the optimal arm requires experimentation with all of the available arms. Furthermore, effective exploration and exploitation typically demands computational resources that grow linearly with the number of arms. Although the former problem can be remedied to some degree when prior knowledge about arm correlation is available, the latter problem persists. In this…
