Повний текст джерелаSince the 1980s a new computational model merging concepts from neural networks and queuing theory was developed. The model was introduced under the name of Random Neural Networks (RNNs), inside the field of Neural Networks. In this thesis, a first contribution consists of an adaptation of quasi-Newton optimisation methods for training the RNN model. In the last decade, a new computational paradigm was introduced in the field of Machine Learning, under the name of Reservoir Computing (RC). One of the pioneers and most diffused RC methods is the Echo State Network (ESN) model. Here, we propose a method based on topographic maps to initialise the ESN procedure. Another contribution of the thesis is the introduction of a new RC model called the Echo State Queueing Network (ESQN), where we use ideas coming from RNNs for the design of the reservoir. An ESQN consists of an ESN where the reservoir has a new dynamics inspired by recurrent RNNs. In this thesis, we position the ESQN method in the global Machine Learning area, and provide examples of their use and performances. Finally, we propose a method for real–time estimation of Speech Quality using the learning tools above described. Audio quality in the Internet can be strongly affected by network conditions. As a consequence, many techniques to evaluate it have been developed. In particular, the ITU-T adopted in 2001 a technique called Perceptual Evaluation of Speech Quality (PESQ) to automatically measuring speech quality. PESQ is a well-known and widely used procedure, providing in general an accurate evaluation of perceptual quality by comparing the original and received voice sequences. The thesis provides a procedure for estimating PESQ output working only with measures taken on the network state and using some properties of the communication system, without any original signal. The experimental results obtained prove the capability of our approach to give good estimations of the speech quality in a real–time context

Повний текст джерелаThis thesis presents research on alternative computing systems, with a focus on analog and neuromimetic computing. The pursuit of more general artificial intelligence has underscored limitations in conventional computing units based on Von Neumann architectures, particularly regarding energy efficiency and complexity. Brain-inspired computing architectures and analog computers are key contenders in this field. Among the various proposed methods, photonic spiking systems offer significant advantages in processing and communication speeds, as well as potential energy efficiency. We propose a novel approach to classification and image recognition tasks using an in-house developed micropillar laser as the artificial neuron. The nonlinearity of the spiking micropillar laser, resulting from the internal dynamics of the system, allows for mapping incoming information, optically injected to the micropillar through gain, into higher dimensions. This enables finding linearly separable regions for classification. The micropillar laser exhibits all fundamental properties of a biological neuron, including excitability, refractory period, and summation effect, with sub-nanosecond characteristic timescales. This makes it a strong candidate in spiking systems where the dynamics of the spike itself carries information, as opposed to systems that consider spiking rates only. We designed and studied several systems using the micropillar laser, based on a reservoir computer with a single physical node that emulates a reservoir computer with several nodes, using different dynamical regimes of the microlaser. These systems achieved higher performance in prediction accuracy of the classes compared to systems without the micropillar. Additionally, we introduce a novel system inspired by receptive fields in the visual cortex, capable of classifying a digit dataset entirely online, eliminating the need for a conventional computer in the process. This system was successfully implemented experimentally using a combined fiber and free-space optical setup, opening promising prospects for ultra-fast, hardware based feature selection and classification systems

Повний текст джерелаL'inversion double-couple et l'inversion du tenseur des moments sont testées sur quatre séismes induits dans le réservoir géothermique de Soultz-sous-Forêts. Les mécanismes obtenus sont en accord avec ceux déterminés par Charléty et al. 2007.
La méthode d'inversion est appliquée à la sismicité de la saline de Vauvert enregistrée par un réseau permanent de deux stations 3-composante. Dans un premier temps, la méthode est testée sur 15 séismes enregistrés durant le déploiement temporaire d'une antenne de quatre capteurs 3-composante. La comparaison entre l'inversion utilisant les deux stations permanentes et l'antenne temporaires et l'inversion utilisant seulement les deux stations permanentes montre des mécanismes au foyer double-couple identiques pour les séismes localisés entre les deux stations permanentes. Dans un deuxième temps, la méthode est appliquée à un essaim de sismicité. Les mécanismes au foyer obtenus pour 532 évènements, indiquent pour la majorité une rupture le long de fractures sub-verticales NE-SW, interprétée comme de probables ruptures sur les plans stratigraphiques des bancs d'insolubles intercalés dans la formation de sel.

Повний текст джерелаMany quantum physics phenomena can only be understood in the context of open system analysis. For example a measurement apparatus is a macroscopic system in contact with a quantum system. Therefore any experiment model needs to take into account open system behaviors. These behaviors can be complex: the interaction of the system with its environment might modify its properties, the interaction may induce memory effects in the system evolution, ... These dynamics are particularly important when studying quantum optic experiments. We are now able to manipulate individual particles. Understanding and controlling the environment influence is therefore crucial. In this thesis we investigate at a theoretical level some commonly used quantum optic procedures. Before the presentation of our results, we introduce and motivate the Markovian approach to open quantum systems. We present both the usual master equation and quantum stochastic calculus. We then introduce the notion of quantum trajectory for the description of continuous indirect measurements. It is in this context that we present the results obtained during this thesis. First, we study the convergence of non demolition measurements. We show that they reproduce the system wave function collapse. We show that this convergence is exponential with a fixed rate. We bound the mean convergence time. In this context, we obtain the continuous time limit of discrete quantum trajectories using martingale change of measure techniques. Second, we investigate the influence of measurement outcome recording on state preparation using reservoir engineering techniques. We show that measurement outcome recording does not influence the convergence itself. Nevertheless, we find that measurement outcome recording modifies the system behavior before the convergence. We recover an exponential convergence with a rate equivalent to the rate without measurement outcome recording. But we also find a new convergence rate corresponding to an asymptotic stability. This last rate is interpreted as an added non demolition measurement. Hence, the system state converges only after a random time. At this time the convergence can be much faster. We also find a bound on the mean convergence time
