Abstract:

In this report we simulate artificial intelligence in animals using genetic algorithms. In similar models, advanced artificial neural networks have been used for decision making. We present two simpler decision-making models. Using two models based on linear and radial basis functions we find similar behaviours as those found in other studies, including food seeking, obstacle avoidance and predator-versus-prey dynamics. The results show that both decision-making models are equally efficient at gathering food and avoiding obstacles. The models differed in survival strategies when faced with dan

Abstract:

Animals evolved to survive in dynamic environments by developing multiple behavioral strategies to adapt and to learn from their interaction with the world. Associative mechanisms and internal representations are at the core brain computation, however, to acquire a complete knowledge of their relevance for behavior it is necessary to take into consideration their embodied nature. In an interdisciplinary effort which integrates methods from computational modeling, robotics, and electrophysiology, this dissertation presents a series of studies that aim at advancing the understanding of the autom

Lors de l’apprentissage, le cerveau est confronté à un problème difficile. Il apprend d’un environnement qui est à la fois stochastique et dynamique, c’est-à-dire qui se caractérise par des distributions de probabilité qui sont susceptibles de changer. La stochasticité incite le cerveau à intégrer un grand nombre d’observations passées pour arriver à une meilleure précision des connaissances acquises, tandis que la propension au changement l’incite à ne prendre en compte que les observations les plus récentes. Cette tension donne lieu à un compromis dans le taux d’apprentissage à utiliser, que

Abstract:

An ambitious long-term goal for neuroevolution, which studies how artificial evolutionary processes can be driven to produce brain-like structures, is to evolve neurocontrollers with a high density of neurons and connections that can adapt and learn from past experience. Yet while neuroevolution has produced successful results in a variety of domains, the scale of natural brains remains far beyond reach. In this dissertation two extensions to the recently introduced Hypercube-based NeuroEvolution of Augmenting Topologies (HyperNEAT) approach are presented that are a step towards more brain-lik

Abstract:

A method for simultaneously segmenting multiple anatomical brain structures from multi-modal MR images has been developed. An artificial neural network (ANN) was trained from a set of feature vectors created by a combination of high-resolution registration methods, atlas based spatial probability distributions, and a training set of 16 expert traced data sets. A set of feature vectors were adapted to increase performance of ANN segmentation; 1) a modified spatial location for structural symmetry of human brain, 2) neighbors along the priors' descent for directional consistency, and 3) candidat

Abstract:

Neuroscience focuses largely on how the brain mediates perception and cognition. However, this leaves open the basic organization and hierarchies of the brain’s neural activity by itself prior to and independent of its role in cognition. A recent model characterizes the brain’s intrinsic features in terms of temporo- spatial dynamical (rather than cognitive) terms – the brain’s spatiotemporal hierarchies shape what is called ‘brain’s intrinsicality’. The brain’s intrinsicality may provide potential applications in designing artificial intelligence (AI). In this dissertation, I explore ‘intrins

Abstract:

The job of classifying or annotating brain tumors from MRI images can be time-consuming and difficult, even for radiologists. To increase the survival chances of a patient, medical practitioners desire a means for quick and accurate diagnosis. While datasets like CIFAR, ImageNet, and SVHN have tens of thousands, hundreds of thousands, or millions of samples, an MRI dataset may not have the same luxury of receiving accurate labels for each image containing a tumor. This work covers three models that classify brain tumors using a combination of convolutional neural networks and of the concept of

Abstract:

La plasticité corticale du cerveau est l'une des principales caractéristiques qui nous permettent d'apprendre et de nous adapter à notre environnement. En effet, le cortex cérébral a la capacité de s'auto-organiser grâce à deux formes de plasticité : la plasticité structurelle qui crée ou coupe les connexions synaptiques entre les neurones, et la plasticité synaptique qui modifie la force des connexions synaptiques. Ces mécanismes sont très probablement à la base d'une caractéristique extrêmement intéressante du développement du cerveau humain : l'association multimodale. Malgré la diversité d

Abstract:

This paper proposes an end-to-end, scale invariant, visual object recognition system, composed of computational components that mimic the cortex in the brain. The system uses a two stage process. The first stage is a filter that extracts scale invariant features from the visual field. The second stage uses inference based spacio-temporal analysis of these features to identify objects in the visual field. The proposed model combines Numenta's Hierarchical Temporal Memory (HTM), with HMAX developed by MIT's Brain and Cognitive Science Department. While these two biologically inspired paradigms a

Abstract:

L'avancement rapide de l'intelligence artificielle (IA) au XXIe siècle a conduit à des percées remarquables dans divers domaines, du traitement du langage naturel à la vision par ordinateur. Cependant, la croissance exponentielle de l'IA pousse les technologies traditionnelles des semi-conducteurs à leurs limites, nécessitant des approches fondamentalement nouvelles en matière de calcul pouvant fournir la puissance et l'efficacité nécessaires. Les nanodispositifs spintroniques, en particulier les nano-oscillateurs à couple de spin (STNOs) et les jonctions tunnel superparamagnétiques perpendicu

Abstract:

Le stress prénatal est un sujet d'intérêt éthologique croissant en raison de ses effets sur la santé humaine et le bien-être des animaux. Cette thése de doctorat s’intéresse à la seiche Sepia officinalis, un modèle pratique dans lequel la progéniture en développement peut être séparée de leurs mères pour examiner diverses sources potentielles de stress en isolement expérimental. Plusieurs catégories de facteurs de stress ont été appliquées aux embryons et aux juvéniles et la progéniture résultante a été testée dans une série d'épreuves physiologiques et comportementales. L'objectif était de dé

Abstract:

After a short introduction concerning the problem of "Artificial Intelligence" (AI) the work continues with a summary of the state of the art.Thereafter, it goes on to profile four different basic scientific views of human beings and AI: symbolism, connectionism, biologism and physicalism. The emphasis is on the elucidation of anthropologically relevant statements to intelligence, spirit, thinking, perception, will, consciousness, self-consciousness, feelings and life.It is demonstrated that the basic views referred to represent greatly abbreviated and distorted pictures of human beings.
