Book excerpt: Nous proposons et développons un modèle original de mémoires associatives s'appuyant sur des réseaux de neurones codés. Les mémoires associatives sont des dispositifs capables d'apprendre des messages binaires puis de les reproduire à partir de fractions de leurs contenus. L'état de l'art est le réseau proposé par Hopfield, dont la diversité de mémorisation - le nombre de messages qu'il peut mémoriser - est inférieure à n/(2log(n)) où n est le nombre de neurones dans le réseau. Notre travail a consisté à tirer parti des techniques de codage et de décodage correcteur d'erreur, plus précisément celle des codes distribués, affn d'accroître considérablement les performances des mémoires associatives. Pour ce faire, nous avons introduit des codes originaux dont les mots de code sont portés par des cliques neurales. Nous montrons que, combinées à des codes locaux parcimonieux, ces cliques neurales offrent une diversité d'apprentissage qui évolue comme le carré du nombre de neurones. Les gains observés viennent de l'utilisation de la parcimonie à plusieurs échelles : d'une part les messages appris sont de longueur bien inférieure à n, d'autre part ils n'utilisent qu'une partie du matériel disponible, que ce soit au niveau des neurones ou de leurs connexions. L'apprentissage est donc localisé, au contraire des réseaux de Hopfield. De plus, ces mémoires bénéficient d'une effcacité - rapport du nombre de bits appris au nombre de bits utilisés - presque maximale. Elles se présentent donc comme une alternative intéressante aux mémoires indexées classiques. Au delà de l'aspect quantitatif, le modèle que nous proposons offre une plausibilité biologique fortement accrue par rapport au modèle de Hopfield. Les concepts de cliques neurales, de winner take all, ou encore de synchronisation temporelle que ce modèle exploite rejoignent les observations récentes rapportées par la littérature neurobiologique. Par ailleurs, elles pourraient ouvrir la voie à la conception de machines cognitives capables de croiser des informations pour en produire de nouvelles car les cliques neurales sont recouvrantes, par leurs sommets ou par leurs arêtes.

This book was released on 2006-06-15 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: As Aristotle stated, scientific explanation is based on deductive argument-yet, Wesley C. Salmon points out, not all deductive arguments are qualified explanations. The validity of the explanation must itself be examined. Four Decades of Scientific Explanation provides a comprehensive account of the developments in scientific explanation that transpired in the last four decades of the twentieth century. It continues to stand as the most comprehensive treatment of the writings on the subject during these years.Building on the historic 1948 essay by Carl G. Hempel and Paul Oppenheim, "Studies in the Logic of Explanation," which introduced the deductive-nomological (D-N) model on which most work on scientific explanation was based for the following four decades, Salmon goes beyond this model's inherent basis of describing empirical knowledge to tells us "not only what, but also why." Salmon examines the predominant models in chronological order and describes their development, refinement, and criticism or rejection.Four Decades of Scientific Explanation underscores the need for a consensus of approach and ongoing evaluations of methodology in scientific explanation, with the goal of providing a better understanding of natural phenomena.

Available in PDF, EPUB and Kindle. Book excerpt: During the First European Congress of Anesthesiology, held in Vienna, Austria, in September, 1962, panel discussions on nineteen different subjects were held, each lasting approxi mately three hours. One, concerning Controversial Aspects of Resuscitation, was later edited by its chairman, PETER SAFAR, and published in 1963. At the request of the publisher, the discussion on hypnosis has been edited in a similar manner. The participants in the discussion on Hypnosis in Anes thesiology had agreed, prior to the meeting, on a list of questions to be debated, and Dr. STOKVIS' introductory statement on the nature of hypnosis was circulated among them in appropriate translations in order to give the debate a starting point. It had also been agreed that no formal papers should be read after this introduction, and that the participants should use at will the German, English or French language. Following each contribution it was the chairman's task to give a brief summary in the two other languages. Discussion was therefore somewhat slowed down and occasionally rendered difficult by misunderstandings or the omission of details. Drs. GUEGUEN, MOSCONI, and VOLGYESI, who were not able. to attend, had sent written contributions which the chairman presented briefly during the discussion. The present text has been worked out of the tape recording of the discussion and the chairman's correspondence with the panelists some time after the meeting. Whenever the original contributions were in French or German, the English translation has been the chairman's.

Available in PDF, EPUB and Kindle. Book excerpt: The environment within which humans interact has changed dramatically since the Industrial Revolution. However, their expectations stem from the same hopes and dreams people have had from the beginning of humankind. When Men Revolt and Why encourages readers to look closer and more deeply into the relationships between humans and the institutions that have originated to help them realize their full potential. The contributors not only examine people, but also the need to change institutions that have outworn their usefulness. When institutions inhibit rather than facilitate everyone's desire to live a full life, the result is likely to be violence. This book offers the ideas of many people who have tried to dig deeper into basic causes of violence. Included in this volume are selections by Aristotle, Tocqueville./Marx and Engels, and Brinton. The ideas they espoused still hold vitality. In his new introduction, James Davies talks about the circumstances under which this book was originally published. In Vietnam, a people were fighting for their autonomy. In the United States, many Americans were protesting against American involvement in the Vietnam War. Blacks were marching for their civil rights. Women were fighting for equality. Time has tempered these conflicts. Davies maintains that we remain ignorant of the elemental forces that impel people and nations to resort to violence. We are usually surprised by their anger and shocked by their violence. Davies asserts that we need to learn more about how humans respond to change so as to prepare ourselves for such responses to change. When Men Revolt and Why is as timely as ever as we deal with uncertainty in various areas of the world— the former Yugoslavia, the Middle East, and Ireland, among others. It is especially pertinent for political scientists, historians, and sociologists.
