Available in PDF, EPUB and Kindle. Book excerpt: Les réseaux de neurones artificiels permettent de résoudre des problèmes que des processeurs classiques ne peuvent pas résoudre sans utiliser une quantité considérable de ressources matérielles. L'analyse et la classification de multiples signaux en sont des exemples. Ces réseaux sont de plus en plus implantés sur des circuits intégrés. Ils ont ainsi pour but d'augmenter les capacités de calcul de processeurs ou d'effectuer leur traitement dans des systèmes embarqués. Dans ce contexte, la surface et la consommation d'énergie du circuit sont prépondérantes. Cependant, le nombre de connexions élevé entre les neurones limite l'intégration d'un réseau contenant un nombre de neurones de l'ordre de la centaine. Le modèle des réseaux de neurones à cliques permet de réduire la densité de connexions au sein d'un réseau, tout en gardant une capacité de stockage d'information plus grande que les modèles standards de réseaux de neurones. Ce modèle est donc approprié pour implanter un réseau de grande taille, à condition de l'intégrer de façon à garder la faible complexité de ses fonctions, pour consommer un minimum d'énergie. Dans cette thèse, un circuit mixte analogique/numérique implantant le modèle des réseaux de neurones à cliques est proposé, ainsi que plusieurs architectures de réseau pouvant contenir un nombre indéterminé de neurones. Cela permet de construire des réseaux de neurones à cliques contenant jusqu'à plusieurs milliers de neurones et consommant peu d'énergie. Pour valider ces concepts, un prototype d'un réseau de neurones à cliques contenant trente neurones sur puce a enfin été fabriqué et testé, en utilisant la technologie Si CMOS 65 nm.

This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les réseaux de neurones artificiels sont particulièrement intéressants pour les implémentations CMOS VLSI (Very Large Scale Integration Complementary Metal-Oxide Semiconductor) car chaque élément parallèle (neurone ou synapse) est relativement simple, permettant l'intégration complète de grands réseaux sur une seule puce. Les multiplieurs, la fonction non-linéaire et sa dérivée sont des éléments clés essentiels dans le traitement du signal analogique et notamment dans la mise en œuvre VLSI analogique de réseaux neuronaux artificiels. Les principales conditions de ce type de circuits sont les suivantes : une faible surface de Silicium et une faible consommation électrique. Pour valider notre approche, nous avons choisi comme type d'application, la classification de cellules cancéreuses (malignes ou bénignes) du sein. Il existe de nombreux types de réseaux de neurones: réseau de neurones à réaction avec rétro-propagation (MLP), réseau de base radiale (RBN), réseau de neurones récurrents (RNN) et autres. Le réseau de neurones étudié dans cette thèse est basé sur l'architecture Multi-Layer Perceptron, formé par la rétro-propagation. L'objectif principal est de trouver les meilleurs compromis et optimisations pour réaliser des circuits avec une technologie mature HCMOS9A 130 nm de STMicroelectronics alimentés sous ±900mV afin d'avoir le coût le plus faible possible. Après avoir choisi le meilleur algorithme (le plus simple et efficace) pour une implémentation VLSI simple, nous avons défini une architecture analogique efficiente. Enfin les briques de base ont été conçues et réalisées avant l'intégration finale sur une faible surface de silicium et une faible consommation de puissance. Pour vérifier et valider le projet de la puce VLSI avant fabrication, une méthodologie de vérification a été proposée dans cette thèse. Elle nous a également permis de définir le cahier des charges de la puce, ainsi que celui des blocs de base.

Jose Delgado-Frias Will Moore April 1991 vii PROLOGUE Artificial intelligence and neural network algorithms/computing have increased in complexity as well as in the number of applications. This in tum has posed a tremendous need for a larger computational power than can be provided by conventional scalar processors which are oriented towards numeric and data manipulations. Due to the artificial intelligence requirements (symbolic manipulation, knowledge representation, non-deterministic computations and dynamic resource allocation) and neural network computing approach (non-programming and learning), a different set of constraints and demands are imposed on the computer architectures for these applications.

Download or read book Introduction to Analog VLSI Design Automation written by Mohammed Ismail and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: Very large scale integration (VLSI) technologies are now maturing with a current emphasis toward submicron structures and sophisticated applications combining digital as well as analog circuits on a single chip. Abundant examples are found on today's advanced systems for telecom munications, robotics, automotive electronics, image processing, intelli gent sensors, etc .. Exciting new applications are being unveiled in the field of neural computing where the massive use of analog/digital VLSI technologies will have a significant impact. To match such a fast technological trend towards single chip ana logi digital VLSI systems, researchers worldwide have long realized the vital need of producing advanced computer aided tools for designing both digital and analog circuits and systems for silicon integration. Ar chitecture and circuit compilation, device sizing and the layout genera tion are but a few familiar tasks on the world of digital integrated circuit design which can be efficiently accomplished by matured computer aided tools. In contrast, the art of tools for designing and producing analog or even analogi digital integrated circuits is quite primitive and still lack ing the industrial penetration and acceptance already achieved by digital counterparts. In fact, analog design is commonly perceived to be one of the most knowledge-intensive design tasks and analog circuits are still designed, largely by hand, by expert intimately familiar with nuances of the target application and integrated circuit fabrication process. The techniques needed to build good analog circuits seem to exist solely as expertise invested in individual designers.

Download or read book Semiorders written by Marc Pirlot and published by Springer Science & Business Media. This book was released on 1997-06-30 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: Semiorder is probably one of the most frequently ordered structures in science. It naturally appears in fields like psychometrics, economics, decision sciences, linguistics and archaeology. It explicitly takes into account the inevitable imprecisions of scientific instruments by allowing the replacement of precise numbers by intervals. The purpose of this book is to dissect this structure and to study its fundamental properties. The main subjects treated are the numerical representations of semiorders, the generalizations of the concept to valued relations, the aggregation of semiorders and their basic role in a general theoretical framework for multicriteria decision-aid methods. Audience: This volume is intended for students and researchers in the fields of decision analysis, management science, operations research, discrete mathematics, classification, social choice theory, and order theory, as well as for practitioners in the design of decision tools.
