Book excerpt: L'hybridation est une technique qui consiste à interconnecter un réseau de neurones biologique et un réseau de neurones artificiel, utilisée dans la recherche en neuroscience et à des fins thérapeutiques. Durant ces trois années de doctorat, ce travail de thèse s'est focalisé sur l'hybridation dans un plan rapproché (communication directe bi-directionnelle entre l'artificiel et le vivant) et dans un plan plus élargies (interopérabilité des systèmes neuromorphiques). Au début des années 2000, cette technique a permis de connecter un système neuromorphique analogique avec le vivant. Ce travail est dans un premier temps, centré autour de la conception d'un réseau de neurones numérique, en vue d'hybridation, dans deux projets multi-disciplinaires en cours dans l'équipe AS2N de l'IMS, présentés dans ce document : HYRENE (ANR 2010-Blan-031601), ayant pour but le développement d'un système hybride de restauration de l'activité motrice dans le cas d'une lésion de la moelle épinière, BRAINBOW (European project FP7-ICT-2011-C), ayant pour objectif l'élaboration de neuro-prothèses innovantes capables de restaurer la communication autour de lésions cérébrales.Possédant une architecture configurable, un réseau de neurones numérique a été réalisé pour ces deux projets. Pour le premier projet, le réseau de neurones artificiel permet d'émuler l'activitéde CPGs (Central Pattern Generator), à l'origine de la locomotion dans le règne animale. Cette activité permet de déclencher une série de stimulations dans la moelle épinière lésée in vitro et de recréer ainsi la locomotion précédemment perdue. Dans le second projet, la topologie du réseau de neurones sera issue de l'analyse et le décryptage des signaux biologiques issues de groupes de neurones cultivés sur des électrodes, ainsi que de modélisations et simulations réalisées par nos partenaires. Le réseau de neurones sera alors capable de réparer le réseau de neurones lésé. Ces travaux de thèse présentent la démarche de conception des deux différents réseaux et des résultats préliminaires obtenus au sein des deux projets. Dans un second temps, ces travaux élargissent l'hybridation à l'interopérabilité des systèmes neuromorphiques. Au travers d'un protocole de communication utilisant Ethernet, il est possible d'interconnecter des réseaux de neurones électroniques, informatiques et biologiques. Dans un futur proche, il permettra d'augmenter la complexité et la taille des réseaux.

Download or read book Handbook of Marketing Decision Models written by Berend Wierenga and published by Springer Science & Business Media. This book was released on 2008-09-11 with total page 621 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marketing models is a core component of the marketing discipline. The recent developments in marketing models have been incredibly fast with information technology (e.g., the Internet), online marketing (e-commerce) and customer relationship management (CRM) creating radical changes in the way companies interact with their customers. This has created completely new breeds of marketing models, but major progress has also taken place in existing types of marketing models. The HANDBOOK OF MARKETING DECISION MODELS presents the state of the art in marketing decision models, dealing with new modeling areas such as customer relationship management, customer value and online marketing, but also describes recent developments in other areas. In the category of marketing mix models, the latest models for advertising, sales promotions, sales management, and competition are dealt with. New developments are presented in consumer decision models, models for return on marketing, marketing management support systems, and in special techniques such as time series and neural nets. Not only are the most recent models discussed, but the book also pays attention to the implementation of marketing models in companies and to applications in specific industries.

This book was released on 2004-08-19 with total page 535 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 11th Conference “Artificial Intelligence: Methodology, Systems, Applications – Semantic Web Challenges” (AIMSA 2004) continued successfully pursuing the main aim of the AIMSA series of conferences – to foster the multidisciplinary community of artificial intelligence researchers, embracing both the theoretic underpinnings of the field and the practical issues involved in development, deployment, and maintenance of systems with intelligent behavior. Since the first conference in 1984 AIMSA has provided an ideal forum for international scientific exchange between Central/Eastern Europe and the rest of the world and it is even more important nowadays in the uni- ing Europe. The current AIMSA edition is focused on Semantic Web methods and technologies. The Internet is changing the everyday services landscape, and the way we do things in almost every domain of our life. Web services are rapidly becoming the enabling technology of today's e-business and e-commerce systems, and will soon transform the Web as it is now into a distributed computation and application framework. The emerging Semantic Web paradigm promises to annotate Web artefacts to enable automated reasoning about them. When applied to e-services, the paradigm hopes to provide substantial automation for activities such as discovery, invocation, assembly, and monitoring of e-services. One hundred and seventy-six interesting papers were submitted to the conference.

This book was released on 2012 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: La fouille de textes est une activité combinant traitements informatiques et données linguistiques avec comme objectif principal l’extraction et l’organisation automatique des informations présentes dans les textes. Deux familles de méthodes permettent d’atteindre ce but : celles à base de connaissances d’experts et celles reposant sur un apprentissage automatique supervisé. Une campagne d’évaluation consiste à confronter les systèmes développés par plusieurs équipes sur un même jeu de données et en un temps limité. Créé en 2005 à l’image des campagnes anglo-saxonnes, le défi fouille de textes (DEFT) est aujourd’hui la seule campagne d’évaluation francophone en fouille de textes. Cet ouvrage rassemble les méthodes utilisées lors des différentes éditions du défi. Les thématiques relèvent de la classification de documents en genres et thèmes, de la fouille d’opinions et de l’identification de la période de parution d’un document.

Download or read book Geoinformation from the Past written by Hendrik Herold and published by Springer. This book was released on 2017-12-21 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hendrik Herold explores potentials and hindrances of using retrospective geoinformation for monitoring, communicating, modeling, and eventually understanding the complex and gradually evolving processes of land cover and land use change. Based on a comprehensive review of literature, available data sets, and suggested algorithms, the author proposes approaches for the two major challenges: To address the diversity of geographical entity representations over space and time, image segmentation is considered a global non-linear optimization problem, which is solved by applying a metaheuristic algorithm. To address the uncertainty inherent to both the data source itself as well as its utilization for change detection, a probabilistic model is developed. Experimental results demonstrate the capabilities of the methodology, e.g., for geospatial data science and earth system modeling.
