Book Description
Cette thèse cherche à optimiser les communications des applications de calcul intensif s'exécutant sur des grappes de PC. En raison de l'usage massif de processeurs multicoeurs, il est désormais impératif de gérer un grand nombre de flux de communication concurrents. Nous avons mis en évidence et analysé les performances décevantes des solutions actuelles dans un tel contexte. Nous avons ainsi proposé une architecture de communication centrée sur l'arbitrage de l'accès aux matériels. Son originalité réside dans la dissociation de l'activité de l'application de celle des cartes réseaux. Notre modèle exploite l'intervalle de temps introduit entre le dépot des requêtes de communication et la disponibilité des cartes réseaux pour appliquer des optimisations de manière opportuniste. NewMadeleine implémente ce concept et se révèle capable d'exploiter les réseaux les plus performants du moment. Des tests synthétiques et portages d'implémentations caractéristiques de MPI ont permis de valider l'architecture proposée.
Une approche dynamique pour l'optimisation des communications concurrentes sur réseaux hautes performance

Adaptive Stream Mining
Author: Albert Bifet
Publisher: IOS Press
ISBN: 1607500906
Category : Computers
Languages : en
Pages : 224
Book Description
This book is a significant contribution to the subject of mining time-changing data streams and addresses the design of learning algorithms for this purpose. It introduces new contributions on several different aspects of the problem, identifying research opportunities and increasing the scope for applications. It also includes an in-depth study of stream mining and a theoretical analysis of proposed methods and algorithms. The first section is concerned with the use of an adaptive sliding window algorithm (ADWIN). Since this has rigorous performance guarantees, using it in place of counters or accumulators, it offers the possibility of extending such guarantees to learning and mining algorithms not initially designed for drifting data. Testing with several methods, including Naïve Bayes, clustering, decision trees and ensemble methods, is discussed as well. The second part of the book describes a formal study of connected acyclic graphs, or 'trees', from the point of view of closure-based mining, presenting efficient algorithms for subtree testing and for mining ordered and unordered frequent closed trees. Lastly, a general methodology to identify closed patterns in a data stream is outlined. This is applied to develop an incremental method, a sliding-window based method, and a method that mines closed trees adaptively from data streams. These are used to introduce classification methods for tree data streams.

Book Description
NEW YORK TIMES BESTSELLER • “A fascinating look at how consumers perceive logos, ads, commercials, brands, and products.”—Time How much do we know about why we buy? What truly influences our decisions in today’s message-cluttered world? In Buyology, Martin Lindstrom presents the astonishing findings from his groundbreaking three-year, seven-million-dollar neuromarketing study—a cutting-edge experiment that peered inside the brains of 2,000 volunteers from all around the world as they encountered various ads, logos, commercials, brands, and products. His startling results shatter much of what we have long believed about what captures our interest—and drives us to buy. Among the questions he explores: • Does sex actually sell? • Does subliminal advertising still surround us? • Can “cool” brands trigger our mating instincts? • Can our other senses—smell, touch, and sound—be aroused when we see a product? Buyology is a fascinating and shocking journey into the mind of today's consumer that will captivate anyone who's been seduced—or turned off—by marketers' relentless attempts to win our loyalty, our money, and our minds.

Interaction and Market Structure
Author: Domenico Delli Gatti
Publisher: Springer Science & Business Media
ISBN: 9783540669791
Category : Business & Economics
Languages : en
Pages : 312
Book Description
This book is a collection of essays which examine how the properties of aggregate variables are influenced by the actions and interactions of heterogenous individuals in different economic contexts. The common denominator of the essays is a critique of the representative agent hypothesis. If this hypothesis were correct, the behaviour of the aggregate variable would simply be the reproduction of individual optimising behaviour. In the methodology of the hard sciences, one of the achievements of the quantum revolution has been the rebuttal of the notion that aggregate behaviour can be explained on the basis of the behaviour of a single unit: the elementary particle does not even exist as a single entity but as a network, a system of interacting units. In this book, new tracks in economics which parallel the developments in physics mentioned above are explored. The essays, in fact are contributions to the analysis of the economy as a complex evolving system of interacting agents.

Cambridge Handbook of Engineering Education Research
Author: Aditya Johri
Publisher: Cambridge University Press
ISBN: 1107785855
Category : Technology & Engineering
Languages : en
Pages : 1124
Book Description
The Cambridge Handbook of Engineering Education Research is the critical reference source for the growing field of engineering education research, featuring the work of world luminaries writing to define and inform this emerging field. The Handbook draws extensively on contemporary research in the learning sciences, examining how technology affects learners and learning environments, and the role of social context in learning. Since a landmark issue of the Journal of Engineering Education (2005), in which senior scholars argued for a stronger theoretical and empirically driven agenda, engineering education has quickly emerged as a research-driven field increasing in both theoretical and empirical work drawing on many social science disciplines, disciplinary engineering knowledge, and computing. The Handbook is based on the research agenda from a series of interdisciplinary colloquia funded by the US National Science Foundation and published in the Journal of Engineering Education in October 2006.
