Book excerpt: Dans cette thèse, nous étudions à un niveau pratique comment nous pouvons réaliser des processus computationnels avec des potentiels d'action (spikes). Nous étudions le problème de la programmation d'un système dynamique modélisé comme un réseau de neurones, et nous considérons des implémentations en software et en hardware. Tout d'abord, nous révisons le modèle de réseau de neurones à temps discret introduit par Soula et al. (2006) et nommé ici BMS. L'intérêt d'utiliser ce modèle est dû à son habileté à reproduire des dynamiques assez riches (voir la section 1.2.4) et aussi permettre d'établir un lien direct entre le potentiel de la membrane et les impulsions de la neurone (spiking activity). En se basant sur une généralisation de ce modèle, nous proposons une méthode afin d'estimer d'une manière efficace les paramètres (les poids synaptiques à différents délais) d'un réseau de neurones à partir de l'observation de sa dynamique (train d'impulsions). L'idée est d'éviter le problème NP-complet qui se pose dès que nous considérons les poids synaptiques et les délais de transmission. Notre méthode permet de définir un système de programmation linéale à partir du modèle BMS et d'effectuer l'estimation des paramètres de manière polynomiale. Ensuite, nous introduisons un mécanisme de réservoir computing (réseau de neurones cachés) afin de faire une estimation plus robuste. Finalement, nous appliquons cette idée à l'implémentation de transformations entrée-sortie, où la méthode est capable d'apprendre les paramètres implicites correspondant à la fonction de transfert. Dans un second temps, nous travaillons au développement d'implémentations numériques permettant de valider nos algorithmes. De plus, nous faisons des contributions au niveau de la programmation de méthodes pour l'analyse de trains d'impulsions et la simulation de réseaux de neurones à impulsion. Nous co-développons une librairie numérique en C++, nommée EnaS et distribuée sous une licence gratuite CeCILL-C. Cette librairie est également compatible avec d'autres simulateurs et peut être utilisée comme un plugin. La dernière partie de la thèse se focalise sur les implémentations en hardware de modèles bio inspirés. Nous faisons le choix de regarder des technologies à bas coût basées sur les FPGA (réseau de portes programmables in situ) et les GPU (processeur graphique). Nous évaluons la réponse des implémentations en hardware des modèles de neurones du type intègre-et-tire quand ils sont soumis aux différents régimes d'activité neuronale. L'implémentation sur le FPGA a été accomplie en faisant une analyse sur la précision et sa performance a été comparée avec celle du GPU.

Available in PDF, EPUB and Kindle. Book excerpt: Understanding and implementing the brain's computational paradigm is the one true grand challenge facing computer researchers. Not only are the brain's computational capabilities far beyond those of conventional computers, its energy efficiency is truly remarkable. This book, written from the perspective of a computer designer and targeted at computer researchers, is intended to give both background and lay out a course of action for studying the brain's computational paradigm. It contains a mix of concepts and ideas drawn from computational neuroscience, combined with those of the author. As background, relevant biological features are described in terms of their computational and communication properties. The brain's neocortex is constructed of massively interconnected neurons that compute and communicate via voltage spikes, and a strong argument can be made that precise spike timing is an essential element of the paradigm. Drawing from the biological features, a mathematics-based computational paradigm is constructed. The key feature is spiking neurons that perform communication and processing in space-time, with emphasis on time. In these paradigms, time is used as a freely available resource for both communication and computation. Neuron models are first discussed in general, and one is chosen for detailed development. Using the model, single-neuron computation is first explored. Neuron inputs are encoded as spike patterns, and the neuron is trained to identify input pattern similarities. Individual neurons are building blocks for constructing larger ensembles, referred to as "columns". These columns are trained in an unsupervised manner and operate collectively to perform the basic cognitive function of pattern clustering. Similar input patterns are mapped to a much smaller set of similar output patterns, thereby dividing the input patterns into identifiable clusters. Larger cognitive systems are formed by combining columns into a hierarchical architecture. These higher level architectures are the subject of ongoing study, and progress to date is described in detail in later chapters. Simulation plays a major role in model development, and the simulation infrastructure developed by the author is described.

This book was released on 2011-04-29 with total page 629 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organic Computing has emerged as a challenging vision for future information processing systems. Its basis is the insight that we will increasingly be surrounded by and depend on large collections of autonomous systems, which are equipped with sensors and actuators, aware of their environment, communicating freely, and organising themselves in order to perform actions and services required by the users. These networks of intelligent systems surrounding us open fascinating ap-plication areas and at the same time bear the problem of their controllability. Hence, we have to construct such systems as robust, safe, flexible, and trustworthy as possible. In particular, a strong orientation towards human needs as opposed to a pure implementation of the tech-nologically possible seems absolutely central. The technical systems, which can achieve these goals will have to exhibit life-like or "organic" properties. "Organic Computing Systems" adapt dynamically to their current environmental conditions. In order to cope with unexpected or undesired events they are self-organising, self-configuring, self-optimising, self-healing, self-protecting, self-explaining, and context-aware, while offering complementary interfaces for higher-level directives with respect to the desired behaviour. First steps towards adaptive and self-organising computer systems are being undertaken. Adaptivity, reconfigurability, emergence of new properties, and self-organisation are hot top-ics in a variety of research groups worldwide. This book summarises the results of a 6-year priority research program (SPP) of the German Research Foundation (DFG) addressing these fundamental challenges in the design of Organic Computing systems. It presents and discusses the theoretical foundations of Organic Computing, basic methods and tools, learning techniques used in this context, architectural patterns and many applications. The final outlook shows that in the mean-time Organic Computing ideas have spawned a variety of promising new projects.

Book excerpt: Quantum mechanics, the subfield of physics that describes the behavior of very small (quantum) particles, provides the basis for a new paradigm of computing. First proposed in the 1980s as a way to improve computational modeling of quantum systems, the field of quantum computing has recently garnered significant attention due to progress in building small-scale devices. However, significant technical advances will be required before a large-scale, practical quantum computer can be achieved. Quantum Computing: Progress and Prospects provides an introduction to the field, including the unique characteristics and constraints of the technology, and assesses the feasibility and implications of creating a functional quantum computer capable of addressing real-world problems. This report considers hardware and software requirements, quantum algorithms, drivers of advances in quantum computing and quantum devices, benchmarks associated with relevant use cases, the time and resources required, and how to assess the probability of success.
