This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les méthodes d'apprentissage profond connaissent une croissance fulgurante. Une explication de ce phénomène est l'essor de la puissance de calcul combiné à l'accessibilité de données en grande quantité. Néanmoins, plusieurs applications de la vie réelle présentent des difficultés: la disponibilité et la qualité des données peuvent être faibles, l'étiquetage des données peut être ardu, etc. Dans ce mémoire, nous examinons deux contextes : celui des données limitées et celui du modèle économique CATS. Pour pallier les difficultés rencontrées dans ces contextes, nous utilisons des modèles d'apprentissage profond pour images avec structure additionnelle. Dans un premier temps, nous examinons les réseaux de scattering et étudions leur version paramétrée sur des petits jeux de données. Dans un second temps, nous adaptons les modèles de diffusion afin de proposer une alternative aux modèles à base d'agents qui sont complexes à construire et à optimiser. Nous vérifions empiriquement la faisabilité de cette démarche en modélisant le marché de l'emploi du modèle CATS. Nous constatons tout d'abord que les réseaux de scattering paramétrés sont performants sur des jeux de données de classification pour des petits échantillons de données. Nous démontrons que les réseaux de scattering paramétrés performent mieux que ceux non paramétrés, c'est-à-dire les réseaux de scattering traditionnels. En effet, nous constatons que des banques de filtres adaptés aux jeux de données permettent d'améliorer l'apprentissage. En outre, nous observons que les filtres appris se différencient selon les jeux de données. Nous vérifions également la propriété de robustesse aux petites déformations lisses expérimentalement. Ensuite, nous confirmons que les modèles de diffusion peuvent être adaptés pour modéliser le marché de l'emploi du modèle CATS dans une approche d'apprentissage profond. Nous vérifions ce fait pour deux architectures de réseau de neurones différentes. De plus, nous constatons que les performances sont maintenues pour différents scénarios impliquant l'apprentissage avec une ou plusieurs séries temporelles issues de CATS, lesquelles peuvent être tirées à partir d'hyperparamètres standards ou de perturbations de ceux-ci.

This book was released on 2014-02-26 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: Le terme promotion de la santé en Afrique, près de 30 ans après l'adoption de la Charte d'Ottawa, continue d'avoir des connotations complètement hors du sens que lui confère cette charte. Cela n'est pas étonnant quand on sait que la notion de santé dans ce contexte africain équivaut à la lutte contre la maladie à travers les soins de santé dispensés par des professionnels de la santé dans des formations sanitaires et les hôpitaux. L'évolution que connait le continent depuis quelques décennies est de donner un peu plus de place à la communauté à travers les relais communautaires dans une participation communautaire vidée de son contenu, car le pouvoir n'est jamais passé entre les mains des communautés.C'est au vu de tout ceci que le présent ouvrage à sa raison d'être pour expliquer les fondements de l'autonomisation communautaire et de la promotion de la santé avec leur importance pour la région africaine en proie aux mauvais indicateurs de santé comparativement aux autres régions du monde.

Available in PDF, EPUB and Kindle. Book excerpt: Emphasizing issues of computational efficiency, Michael Kearns and Umesh Vazirani introduce a number of central topics in computational learning theory for researchers and students in artificial intelligence, neural networks, theoretical computer science, and statistics. Emphasizing issues of computational efficiency, Michael Kearns and Umesh Vazirani introduce a number of central topics in computational learning theory for researchers and students in artificial intelligence, neural networks, theoretical computer science, and statistics. Computational learning theory is a new and rapidly expanding area of research that examines formal models of induction with the goals of discovering the common methods underlying efficient learning algorithms and identifying the computational impediments to learning. Each topic in the book has been chosen to elucidate a general principle, which is explored in a precise formal setting. Intuition has been emphasized in the presentation to make the material accessible to the nontheoretician while still providing precise arguments for the specialist. This balance is the result of new proofs of established theorems, and new presentations of the standard proofs. The topics covered include the motivation, definitions, and fundamental results, both positive and negative, for the widely studied L. G. Valiant model of Probably Approximately Correct Learning; Occam's Razor, which formalizes a relationship between learning and data compression; the Vapnik-Chervonenkis dimension; the equivalence of weak and strong learning; efficient learning in the presence of noise by the method of statistical queries; relationships between learning and cryptography, and the resulting computational limitations on efficient learning; reducibility between learning problems; and algorithms for learning finite automata from active experimentation.

Download or read book Reinforcement Learning second edition written by Richard S. Sutton and published by MIT Press. This book was released on 2018-11-13 with total page 549 pages. Available in PDF, EPUB and Kindle. Book excerpt: The significantly expanded and updated new edition of a widely used text on reinforcement learning, one of the most active research areas in artificial intelligence. Reinforcement learning, one of the most active research areas in artificial intelligence, is a computational approach to learning whereby an agent tries to maximize the total amount of reward it receives while interacting with a complex, uncertain environment. In Reinforcement Learning, Richard Sutton and Andrew Barto provide a clear and simple account of the field's key ideas and algorithms. This second edition has been significantly expanded and updated, presenting new topics and updating coverage of other topics. Like the first edition, this second edition focuses on core online learning algorithms, with the more mathematical material set off in shaded boxes. Part I covers as much of reinforcement learning as possible without going beyond the tabular case for which exact solutions can be found. Many algorithms presented in this part are new to the second edition, including UCB, Expected Sarsa, and Double Learning. Part II extends these ideas to function approximation, with new sections on such topics as artificial neural networks and the Fourier basis, and offers expanded treatment of off-policy learning and policy-gradient methods. Part III has new chapters on reinforcement learning's relationships to psychology and neuroscience, as well as an updated case-studies chapter including AlphaGo and AlphaGo Zero, Atari game playing, and IBM Watson's wagering strategy. The final chapter discusses the future societal impacts of reinforcement learning.

Download or read book Your Mindful Compass written by Andrea Maloney Schara and published by . This book was released on 2013-12-01 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Your Mindful Compass" takes us behind the emotional curtain to see the mechanisms regulating individuals in social systems. There is great comfort and wisdom in knowing we can increase our awareness to manage the swift and ancient mechanisms of social control. We can gain greater flexibility by seeing how social controls work in systems from ants to humans. To be less controlled by others, we learn how emotional systems influence our relationship-oriented brain. People want to know what goes on in families that give rise to amazing leaders and/or terrorists. For the first time in history we can understand the systems in which we live. The social sciences have been accumulating knowledge since the early fifties as to how we are regulated by others. S. Milgram, S. Ashe, P. Zimbardo and J. Calhoun, detail the vulnerability to being duped and deceived and the difficulty of cooperating when values differ. Murray Bowen, M.D., the first researcher to observe several live-in families, for up to three years, at the National Institute of Mental Health. Describing how family members overly influence one another and distribute stress unevenly, Bowen described both how symptoms and family leaders emerge in highly stressed families. Our brain is not organized to automatically perceive that each family has an emotional system, fine-tuned by evolution and "valuing" its survival as a whole, as much as the survival of any individual. It is easier to see this emotional system function in ants or mice but not in humans. The emotional system is organized to snooker us humans: encouraging us to take sides, run away from others, to pressure others, to get sick, to blame others, and to have great difficulty in seeing our part in problems. It is hard to see that we become anxious, stressed out and even that we are difficult to deal with. But "thinking systems" can open the doors of perception, allowing us to experience the world in a different way. This book offers both coaching ideas and stories from leaders as to strategies to break out from social control by de-triangling, using paradoxes, reversals and other types of interruptions of highly linked emotional processes. Time is needed to think clearly about the automatic nature of the two against one triangle. Time and experience is required as we learn strategies to put two people together and get self outside the control of the system. In addition, it takes time to clarify and define one's principles, to know what "I" will or will not do and to be able to take a stand with others with whom we are very involved. The good news is that systems' thinking is possible for anyone. It is always possible for an individual to understand feelings and to integrate them with their more rational brains. In so doing, an individual increases his or her ability to communicate despite misunderstandings or even rejection from important others. The effort involved in creating your Mindful Compass enables us to perceive the relationship system without experiencing it's threats. The four points on the Mindful Compass are: 1) Action for Self, 2) Resistance to Forward Progress, 3) Knowledge of Social Systems and the 4) The Ability to Stand Alone. Each gives us a view of the process one enters when making an effort to define a self and build an emotional backbone. It is not easy to find our way through the social jungle. The ability to know emotional systems well enough to take a position for self and to become more differentiated is part of the natural way humans cope with pressure. Now people can use available knowledge to build an emotional backbone, by thoughtfully altering their part in the relationship system. No one knows how far one can go by making an effort to be more of a self-defined individual in relationships to others. Through increasing emotional maturity, we can find greater individual freedom at the same time that we increase our ability to cooperate and to be close to others.

Available in PDF, EPUB and Kindle. Book excerpt: "'Gender Matters' is a manual aimed to assist educators and youth leaders work on issues of gender and gender-based violence with young people. This publication presents theoretical information, methods and resources for education and training activities, along with concrete exercises that users can put into practice in their daily work. Violence is a serious issue which directly affects the lives of many young people. It often results in lasting damage to their well-being and integrity, putting even their lives at risk. Gender-based violence, including violence against women, remains a key human rights challenge in contemporary Europe and in the world. Working with young people on human rights education is one way of preventing gender-based violence from occurring. By raising awareness on why and how it manifests and exploring its impact on people and in society, gender-based violence will no longer go undetected. Gender really does matter, to women, to men, to young people - to all of us. This manual serves to explore these human rights issues and act upon them."--Book jacket.

Download or read book Recent Progress in Artificial Neural Networks written by Jeremy Rogerson and published by . This book was released on 2019-06-13 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: Artificial neural networks (ANNs) are computing systems that are motivated by the design and functioning of biological neural networks. Its design is driven by the goal of solving problems in a manner that mimics the working of the human brain. To achieve this, a system of artificial neurons is constructed, which transmits signals through connections. ANN can be programmed to deliver on the functionalities of data processing, classification, function approximation, robotics and control. Its use, however, requires an understanding of the learning algorithm, choice of model and robustness. Due to its diverse capabilities, ANN has potential applications in medical diagnosis, finance, ocean modeling, vehicle control, face identification, among many others. This book contains some path-breaking studies in the field of artificial neural networks. The ever-growing need of advanced technology is the reason that has fueled the research in the field of artificial neural networks in recent times. Coherent flow of topics, student-friendly language and extensive use of examples make this book an invaluable source of knowledge.
