Available in PDF, EPUB and Kindle. Book excerpt: Cette thèse étudie les problèmes de contrôle qui se posent lorsqu'on veut gérer des réseaux de processeurs à mémoires locales ou machines distribuées. Le chapitre 1 a pour objet la mise en évidence de l'expression de problèmes distribués sous forme d'équations à l'aide du concept de point fixe qui offre une vision unificatrice de l'algorithmique distribuée. Le chapitre 2 propose une modélisation markovienne pour représenter localement les processus distribués et globalement les relations s'établissant entre ces processus. L'intérêt théorique et la pertinence de ce modèle markovien sont prouvés par son application à plusieurs problèmes: en effet, il permet de résoudre de façon satisfaisante et complète le problème du "dîner des philosophes" (chapitre 9), celui de l'exclusion mutuelle (chapitre 4) et celui de l'inter blocage (chapitre 5) en définissant une famille de de règles de bon fonctionnement. Dans chacun de ces 3 chapitres, sont traitées les implications des comportements locaux sur le comportement global et le réglage des paramètres du modèle afin d'obtenir un fonctionnement optimal des algorithmes distribués (selon des critères adéquats). Dans ces études, l'équité se révèle avoir un rôle important ct dans le chapitre 6, cette notion est étudiée après avoir été mis en évidence par des expériences de programmation en Occam sur réseau de Transputers. Enfin, le chapitre 7 présente l'application du calcul diffusant à la résolution du problème de détection de situations stables exprimées par des équations de point-fixe.

Available in PDF, EPUB and Kindle. Book excerpt: Nous présentons dans cette thèse une étude sur des algorithmes distribués asynchrones et déterministes de contrôle. Un système distribué consiste en un réseau de sites (processeurs, ordinateurs ou réseaux locaux). Dans cette thèse, nous ne considérons que des réseaux de sites communicants n'ayant ni mémoire partagée, ni horloge globale. De nombreux problèmes de l'algorithmique distribuée sont réductibles à la construction d'un arbre couvrant qui est la structure de contrôle qui nous intéresse. Nous étudions deux types d'algorithmes: ceux utilisant la notion de phase logique et les autres qui ne considèrent aucun mécanisme de synchronisation. Ces derniers ont des comportements imprévisibles améliorent la tolérance aux fautes. Nous présentons un nouvel algorithme de ce type associé à une élection qui n'est pas une recherche d'extremum contrairement a l'usage. Cet algorithme est comparable au meilleur algorithme connu qui utilise des jetons et des phases logiques induisant un comportement plus séquentiel. D'autres algorithmes, construisant des ac contraints, sont considèrés. En particulier, l'ac de diamètre minimum qui est, à notre connaissance, un problème qui n'a jamais été étudié dans ce domaine. Le diamètre d'un graphe est la somme des poids des arêtes du plus long des plus courts chemins. Si nous considérons la complexité temporelle, cette contrainte est d'un intérêt évident. Nous proposons différents algorithmes suivant que la tolérance aux fautes est nécessaire ou non. Finalement, l'étude pratique des algorithmes distribués sur des réseaux de grande taille nous a conduit à la construction d'un simulateur. Il permet l'exécution d'un même code source sur des machines séquentielles ou parallèles

Available in PDF, EPUB and Kindle. Book excerpt: L'avenir des systèmes client-serveur passera nécessairement par un développement de l'algorithmique distribuée. Cependant, et même si les premières recherches sur ce domaine datent de bientôt 20 ans, il faut reconnaître que celui-ci fait figure de parent pauvre de l'informatique, et plus particulièrement l'analyse des algorithmes. Evaluation des algorithmes distribués propose un tour d'horizon de l'état de la complexité des algorithmes et de ses méthodes. Il présente l'analyse de la quasi-totalité des algorithmes fondamentaux du domaine, assortie de nombreux exercices corrigés. Il s'adresse à un public d'étudiants, enseignants, chercheurs et ingénieurs, voire aux curieux de toute nature.

Book excerpt: President Putin’s explicit declaration that the country that makes progress in artificial intelligence will rule the world has launched a new race for dominance. In this era of cognitive competition and total automation, every country understands that it must rapidly adopt AI or go bust. To stay competitive a country must have a strategy. But how should a government proceed? What areas it must focus on? Where should it even start? This book provides answers to these important, yet pertinent, questions and more. Presenting the viewpoints of global experts and thought leaders on key issues relating to AI and government policies, this book directs us to the future.

Available in PDF, EPUB and Kindle. Book excerpt: Why policies should be based on careful consideration of their costs and benefits rather than on intuition, popular opinion, interest groups, and anecdotes. Opinions on government policies vary widely. Some people feel passionately about the child obesity epidemic and support government regulation of sugary drinks. Others argue that people should be able to eat and drink whatever they like. Some people are alarmed about climate change and favor aggressive government intervention. Others don't feel the need for any sort of climate regulation. In The Cost-Benefit Revolution, Cass Sunstein argues our major disagreements really involve facts, not values. It follows that government policy should not be based on public opinion, intuitions, or pressure from interest groups, but on numbers—meaning careful consideration of costs and benefits. Will a policy save one life, or one thousand lives? Will it impose costs on consumers, and if so, will the costs be high or negligible? Will it hurt workers and small businesses, and, if so, precisely how much? As the Obama administration's “regulatory czar,” Sunstein knows his subject in both theory and practice. Drawing on behavioral economics and his well-known emphasis on “nudging,” he celebrates the cost-benefit revolution in policy making, tracing its defining moments in the Reagan, Clinton, and Obama administrations (and pondering its uncertain future in the Trump administration). He acknowledges that public officials often lack information about costs and benefits, and outlines state-of-the-art techniques for acquiring that information. Policies should make people's lives better. Quantitative cost-benefit analysis, Sunstein argues, is the best available method for making this happen—even if, in the future, new measures of human well-being, also explored in this book, may be better still.

Book excerpt: “Simplexity, as I understand it, is the range of solutions living organisms have found, despite the complexity of natural processes, to enable the brain to prepare an action and plan for the consequences of it. These solutions are simplifying principles that enable the processing of information or situations, by taking into account past experience and anticipating the future. They are neither caricatures, shortcuts, or summaries. They are new ways of asking questions, sometimes at the cost of occasional detours, in order to achieve faster, more elegant, more effective actions.” A. B. As Alain Berthoz demonstrates in this profoundly original book, simplicity is never easy; it requires suppressing, selecting, connecting, thinking, in order to then act in the best way possible. And what if we, in turn, are inspired by the living world to process the complexity that surrounds us? Alain Berthoz is professor at the Collège de France where he is co-director of the Laboratoire de physiologie de la perception et de l’action. [Laboratory for the physiology of perception and action]. He is a member of the French Academy of Sciences, and is the author of Le Sens du mouvement [The Brain's Sense of Movement] and La Décision [Emotion and Reason].

This book was released on 2019-05-17 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent advances in digital technology and big data have allowed FinTech (financial technology) lending to emerge as a potentially promising solution to reduce the cost of credit and increase financial inclusion. However, machine learning (ML) methods that lie at the heart of FinTech credit have remained largely a black box for the nontechnical audience. This paper contributes to the literature by discussing potential strengths and weaknesses of ML-based credit assessment through (1) presenting core ideas and the most common techniques in ML for the nontechnical audience; and (2) discussing the fundamental challenges in credit risk analysis. FinTech credit has the potential to enhance financial inclusion and outperform traditional credit scoring by (1) leveraging nontraditional data sources to improve the assessment of the borrower’s track record; (2) appraising collateral value; (3) forecasting income prospects; and (4) predicting changes in general conditions. However, because of the central role of data in ML-based analysis, data relevance should be ensured, especially in situations when a deep structural change occurs, when borrowers could counterfeit certain indicators, and when agency problems arising from information asymmetry could not be resolved. To avoid digital financial exclusion and redlining, variables that trigger discrimination should not be used to assess credit rating.

Cicilline, Chairman, Subcommittee on Antitrust, Commercial and Administrative LawIn June 2019 the Committee on the Judiciary initiated a bipartisan investigation into the state of competition online, spearheaded by the Subcommittee on Antitrust, Commercial and Administrative Law. As part of a top-to -bottom review of the market, the Subcommittee examined the dominance of Amazon, Apple, Facebook, and Google, and their business practices to determine how their power affects our economy and our democracy. Additionally, the Subcommittee performed a review of existing antitrust laws, competition policies, and current enforcement levels to assess whether they are adequate to market power and anticompetitive conduct in digital markets. Over the course of our investigation, we collected extensive evidence from these companies aswell as from third parties - totaling nearly 1.3 million documents . We held seven hearings to review the effects of market power online including on the free and diverse press, innovation, and privacy and a final hearing to examine potential solutions to concerns identified during the investigation and to inform this Report's recommendations .
