Book excerpt: LES TRAVAUX DE RECHERCHE PRESENTES DANS CE MEMOIRE S'INSCRIVENT DANS LE CADRE DES SYSTEMES DE RECHERCHE DOCUMENTAIRE ET ONT UN DOUBLE OBJECTIF. LE PREMIER CONSISTE A LA REALISATION D'UN SYSTEME DE RECHERCHE D'INFORMATIONS TEXTUELLES VOLUMINEUSES, RECOLTE, UTILISANT LE LANGAGE NATUREL COMME SOURCE D'INFORMATIONS ET COMME MOYEN D'INTERROGATION. NOTRE CONTRIBUTION A ALORS PERMIS: LA CONSTRUCTION D'UN MODELE DE REPRESENTATION ET D'ORGANISATION DES INFORMATIONS, LA MISE EN UVRE D'UNE PROCEDURE D'INTERROGATION QUI PERMET LA COLLABORATION DE METHODES DE RECHERCHES EN LANGAGE QUASI NATUREL ET DE METHODES DE RECHERCHES MULTI-CRITERES. LE SECOND OBJECTIF RENTRE DANS LE CADRE DU DEVELOPPEMENT DES SYSTEMES DYNAMIQUES DE RECHERCHE D'INFORMATIONS. NOTRE BUT EST LA REALISATION D'UN SYSTEME DE RECHERCHE D'INFORMATIONS BASE SUR LES RESEAUX NEURO-MIMETIQUES. LE MODELE QUE NOUS PROPOSONS, PRESENTE LES CARACTERISTIQUES SUIVANTES: IL EST CONSTRUIT SUIVANT UNE ARCHITECTURE A TROIS COUCHES INTERCONNECTEES, POUR MODELISER L'ENSEMBLE DE LA CONNAISSANCE DOCUMENTAIRE. ELLE EST EN EFFET CONSTITUEE D'UNE COUCHE DE REQUETES ET D'UNE COUCHE DE DOCUMENTS CONNECTEES A UNE COUCHE DE TERMES D'INDEXATION; IL PERMET DE REALISER DEUX FONCTIONS. LA PREMIERE EST LA RECHERCHE D'INFORMATIONS. LE RESEAU OFFRE A L'UTILISATEUR DES MOYENS, LORS DE L'INTERROGATION DE LA BASE DE DOCUMENTS, POUR REFORMULER AUTOMATIQUEMENT LES REQUETES ET POUR SELECTIONNER LES DOCUMENTS SUSCEPTIBLES DE REPONDRE A SA DEMANDE. CETTE TACHE EST REALISEE PAR UN PROCESSUS D'ACTIVATION/PROPAGATION POUR LEQUEL NOUS AVONS PROPOSE DES REGLES D'ACTIVATION/PROPAGATION INTER-COUCHES ET INTRA-COUCHES. LA SECONDE FONCTION EST LE MECANISME D'APPRENTISSAGE ET DE RESTRUCTURATION DE LA BASE. IL CONSISTE, D'UNE FACON GENERALE, A MODIFIER LES LIENS ENTRE LES DIFFERENTES CELLULES DU RESEAU

Download or read book Self Organization and Associative Memory written by Teuvo Kohonen and published by Springer. This book was released on 2012-12-06 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two significant things have happened since the writing of the first edition in 1983. One of them is recent arousal of strong interest in general aspects of "neural computing", or "neural networks", as the previous neural models are nowadays called. The incentive, of course, has been to develop new com puters. Especially it may have been felt that the so-called fifth-generation computers, based on conventional logic programming, do not yet contain in formation processing principles of the same type as those encountered in the brain. All new ideas for the "neural computers" are, of course, welcome. On the other hand, it is not very easy to see what kind of restrictions there exist to their implementation. In order to approach this problem systematically, cer tain lines of thought, disciplines, and criteria should be followed. It is the pur pose of the added Chapter 9 to reflect upon such problems from a general point of view. Another important thing is a boom of new hardware technologies for dis tributed associative memories, especially high-density semiconductor circuits, and optical materials and components. The era is very close when the parallel processors can be made all-optical. Several working associative memory archi tectures, based solely on optical technologies, have been constructed in recent years. For this reason it was felt necessary to include a separate chapter (Chap. 10) which deals with the optical associative memories. Part of its con tents is taken over from the first edition.

Download or read book Principles of Neurodynamics written by Frank Rosenblatt and published by . This book was released on 1962 with total page 648 pages. Available in PDF, EPUB and Kindle. Book excerpt: Part I attempts to review the background, basic sources of data, concepts, and methodology to be employed in the study of perceptrons. In Chapter 2, a brief review of the main alternative approaches to the development of brain models is presented. Chapter 3 considers the physiological and psychological criteria for a suitable model, and attempts to evaluate the empirical evidence which is available on several important issues. Chapter 4 contains basic definitions and some of the notation to be used in later sections are presented. Parts II and III are devoted to a summary of the established theoretical results obtained to date. Part II (Chapters 5 through 14) deals with the theory of three-layer series-coupled perceptrons, on which most work has been done to date. Part III (Chapters 15 through 20) deals with the theory of multi-layer and cross-coupled perceptrons. Part IV is concerned with more speculative models and problems for future analysis. Of necessity, the final chapters become increasingly heuristic in character, as the theory of perceptrons is not yet complete, and new possibilities are continually coming to light. (Author).

Download or read book GeoHumanities written by Michael Dear and published by Routledge. This book was released on 2011-04-14 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past decade, there has been a convergence of transdisciplinary thought characterized by geography’s engagement with the humanities, and the humanities’ integration of place and the tools of geography into its studies. GeoHumanities maps this emerging intellectual terrain with thirty cutting edge contributions from internationally renowned scholars, architects, artists, activists, and scientists. This book explores the humanities’ rapidly expanding engagement with geography, and the multi-methodological inquiries that analyze the meanings of place, and then reconstructs those meanings to provoke new knowledge as well as the possibility of altered political practices. It is no coincidence that the geohumanities are forcefully emerging at a time of immense intellectual and social change. This book focuses on a range of topics to address urgent contemporary imperatives, such as the link between creativity and place; altered practices of spatial literacy; the increasing complexity of visual representation in art, culture, and science and the ubiquitous presence of geospatial technologies in the Information Age. GeoHumanties is essential reading for students wishing to understand the intellectual trends and forces driving scholarship and research at the intersections of geography and the humanities disciplines. These trends hold far-reaching implications for future work in these disciplines, and for understanding the changes gripping our societies and our globalizing world.

Download or read book Chemical Principles of Textile Conservation written by Agnes Timar-Balazsy and published by Routledge. This book was released on 2012-09-10 with total page 466 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'Chemical Principles of Textile Conservation' provides must-have knowledge for conservators who do not always have a scientific background. This vital book brings together from many sources the material science necessary to understand the properties, deterioration and investigation of textile artefacts. It also aids understanding of the chemical processes during various treatments, such as: cleaning; humidification; drying; disinfestation; disinfection; and the use of adhesives and consolidants in conservation of historical textiles. Textile conservators will now have ready access to the necessary knowledge to understand the chemistry of the objects they are asked to treat and to make informed decisions about how to preserve textiles. The combination of a chemist and a conservator provides the perfect authorial team. It ensures a unique dual function of the text which provides textile conservators with vital chemical knowledge and gives scientists an understanding of textile conservation necessary to direct their research. The many practical examples and case studies illustrate the utility of the relatively large chemical introduction and the essential chemical information which is included. The case studies, many illustrated in colour, range from the treatment of the Ghandis' clothes, high-altitude flying suits and a Mary Quant raincoat, to the Hungarian Coronation Mantle.

Available in PDF, EPUB and Kindle. Book excerpt: Emphasizing issues of computational efficiency, Michael Kearns and Umesh Vazirani introduce a number of central topics in computational learning theory for researchers and students in artificial intelligence, neural networks, theoretical computer science, and statistics. Emphasizing issues of computational efficiency, Michael Kearns and Umesh Vazirani introduce a number of central topics in computational learning theory for researchers and students in artificial intelligence, neural networks, theoretical computer science, and statistics. Computational learning theory is a new and rapidly expanding area of research that examines formal models of induction with the goals of discovering the common methods underlying efficient learning algorithms and identifying the computational impediments to learning. Each topic in the book has been chosen to elucidate a general principle, which is explored in a precise formal setting. Intuition has been emphasized in the presentation to make the material accessible to the nontheoretician while still providing precise arguments for the specialist. This balance is the result of new proofs of established theorems, and new presentations of the standard proofs. The topics covered include the motivation, definitions, and fundamental results, both positive and negative, for the widely studied L. G. Valiant model of Probably Approximately Correct Learning; Occam's Razor, which formalizes a relationship between learning and data compression; the Vapnik-Chervonenkis dimension; the equivalence of weak and strong learning; efficient learning in the presence of noise by the method of statistical queries; relationships between learning and cryptography, and the resulting computational limitations on efficient learning; reducibility between learning problems; and algorithms for learning finite automata from active experimentation.
