Successive Reduction of Arms in Multi-Armed Bandits
2011
The relevance of the multi-armed bandit problem has risen in the past few years with the need for online optimization techniques in Internet systems, such as online advertisement and news article recommendation. At the same time, these applications reveal that state-of-the-art solution schemes do not scale well with the number of bandit arms. In this paper, we present two types of Successive Reduction (SR) strategies - 1) Successive Reduction Hoeffding (SRH) and 2) Successive Reduction Order Statistics (SRO). Both use an Order Statistics based Thompson Sampling method for arm selection, and then successively eliminate bandit arms from consideration based on a confidence threshold. While SRH…
Inflation, quantum fields, and CMB anisotropies
2009
Revert field Inflationary cosmology has proved to be the most successful at predicting the properties of the anisotropies observed in the cosmic microwave background (CMB). In this essay we show that quantum field renormalization significantly influences the generation of primordial perturbations and hence the expected measurable imprint of cosmological inflation on the CMB. However, the new predictions remain in agreement with observation, and in fact favor the simplest forms of inflation. In the near future, observations of the influence of gravitational waves from the early universe on the CMB will test our new predictions.
Validation of the French national health insurance information system as a tool in vaccine safety assessment: Application to febrile convulsions afte…
2013
In the French national health insurance information system (SNIIR-AM), routine records of health claimed reimbursements are linked to hospital admissions for the whole French population. The main focus of this work is the usability of this system for vaccine safety assessment programme. Self-controlled case series analyses were performed using an exhaustive SNIIR-AM extraction of French children aged less than 3 years, to investigate the relationship between MMR immunization and children hospitalizations for febrile convulsions, a well-documented rare adverse event, over 2009-2010. The results suggest a significant increase of febrile convulsions during the 6-11 days period following any MM…
Cost-Efficient On-Chip Routing Implementations for CMP and MPSoC Systems
2011
[EN] The high-performance computing domain is enriching with the inclusion of networks-on-chip (NoCs) as a key component of many-core (CMPs or MPSoCs) architectures. NoCs face the communication scalability challenge while meeting tight power, area, and latency constraints. Designers must address new challenges that were not present before. Defective components, the enhancement of application-level parallelism, or power-aware techniques may break topology regularity, thus, efficient routing becomes a challenge. This paper presents universal logic-based distributed routing (uLBDR), an efficient logic-based mechanism that adapts to any irregular topology derived from 2-D meshes, instead of usi…

Les vies étudiantes : tendances et inégalités
2016
National audience; On recense aujourd'hui plus de 2,4 millions d'étudiants en France. Une population dont les effectifs ne cessent de croître et qui se révèle être de plus en plus diversifiée. Se référer à « l'étudiant moyen » n'a donc pas plus de sens aujourd'hui qu'il n'en avait lors de la mise en place de la première enquête Conditions de vie des étudiants en 1994. Il en est de même de la vie étudiante qu'il est difficile de réduire à quelques clichés. Le seul fait d'être étudiant est loin d'homogénéiser les conditions de vie d'un public aux caractéristiques, aux expériences et aux attentes de plus en plus diversifiées. Le sexe, l'âge, la formation suivie, le parcours antérieur, la situa…
Pleistocene allopatric differentiation followed by recent range expansion explains the distribution and molecular diversity of two congeneric crustac…
2021
AbstractPleistocene glaciations had a tremendous impact on the biota across the Palaearctic, resulting in strong phylogeographic signals of range contraction and rapid postglacial recolonization of the deglaciated areas. Here, we explore the diversity patterns and history of two sibling species of passively dispersing taxa typical of temporary ponds, fairy shrimps (Anostraca). We combine mitochondrial (COI) and nuclear (ITS2 and 18S) markers to conduct a range-wide phylogeographic study including 56 populations of Branchinecta ferox and Branchinecta orientalis in the Palaearctic. Specifically, we investigate whether their largely overlapping ranges in Europe resulted from allopatric differe…
Géohistoire du lien réseau/territoire en France entre 1830 et 1930 : une approche géographiquement pondérée
2015
National audience; La question de l’établissement d’un lien entre le réseau et le territoire est une problématique d’aménagement éminemment d’actualité. Sujette à débat depuis des décennies, elle est un thème pluridisciplinaire. La littérature scientifique est abondante à propos des relations qu’entretiennent ces concepts élémentaires de la géographie théorique (Bunge, 1962) et démontre certainement la difficulté de mesurer leurs liens. Apparu dès la construction des chemins de fer au début du XIXème siècle, le rapport entre réseau et territoire a souvent été décrété de manière catégorique.
Change of Direction Biomechanics in a 180-Degree Pivot Turn and the Risk for Noncontact Knee Injuries in Youth Basketball and Floorball Players.
2021
Background: Studies investigating biomechanical risk factors for knee injuries in sport-specific tasks are needed. Purpose: To investigate the association between change of direction (COD) biomechanics in a 180-degree pivot turn and knee injury risk among youth team sport players. Study Design: Cohort study; Level of evidence, 2. Methods: A total of 258 female and male basketball and floorball players (age range, 12-21 years) participated in the baseline COD test and follow-up. Complete data were obtained from 489 player-legs. Injuries, practice, and game exposure were registered for 12 months. The COD test consisted of a quick ball pass before and after a high-speed 180-degree pivot turn o…
