Available in PDF, EPUB and Kindle. Book excerpt: Building algorithms that classify images on a large scale is an essential task due to the difficulty in searching massive amount of unlabeled visual data available on the Internet. We aim at classifying images based on their content to simplify the manageability of such large-scale collections. Large-scale image classification is a difficult problem as datasets are large with respect to both the number of images and the number of classes. Some of these classes are fine grained and they may not contain any labeled representatives. In this thesis, we use state-of-the-art image representations and focus on efficient learning methods. Our contributions are (1) a benchmark of learning algorithms for large scale image classification, and (2) a novel learning algorithm based on label embedding for learning with scarce training data. Firstly, we propose a benchmark of learning algorithms for large scale image classification in the fully supervised setting. It compares several objective functions for learning linear classifiers such as one-vs-rest, multiclass, ranking and weighted average ranking using the stochastic gradient descent optimization. The output of this benchmark is a set of recommendations for large-scale learning. We experimentally show that, online learning is well suited for large-scale image classification. With simple data rebalancing, One-vs-Rest performs better than all other methods. Moreover, in online learning, using a small enough step size with respect to the learning rate is sufficient for state-of-the-art performance. Finally, regularization through early stopping results in fast training and a good generalization performance. Secondly, when dealing with thousands of classes, it is difficult to collect sufficient labeled training data for each class. For some classes we might not even have a single training example. We propose a novel algorithm for this zero-shot learning scenario. Our algorithm uses side information, such as attributes to embed classes in a Euclidean space. We also introduce a function to measure the compatibility between an image and a label. The parameters of this function are learned using a ranking objective. Our algorithm outperforms the state-of-the-art for zero-shot learning. It is flexible and can accommodate other sources of side information such as hierarchies. It also allows for a smooth transition from zero-shot to few-shots learning.

Available in PDF, EPUB and Kindle. Book excerpt: Le Transfert de Connaissance (Knowledge Transfer or Transfer Learning) est une solution prometteuse au difficile problème de l'apprentissage des réseaux profonds au moyen de bases d'apprentissage de petite taille, en présence d'une grande variabilité visuelle intra-classe. Dans ce travail, nous reprenons ce paradigme, dans le but d'étendre les capacités des CNN les plus récents au problème de la classification. Dans un premier temps, nous proposons plusieurs techniques permettant, lors de l'apprentissage et de la prédiction, une réduction des ressources nécessaires - une limitation connue des CNN. (i) En utilisant une méthode hybride combinant des techniques classiques comme des Bag-Of-Words (BoW) avec des CNN. (iv) En introduisant une nouvelle méthode d'agrégation intégrée à une structure de type CNN ainsi qu'un modèle non-linéaire s'appuyant sur des parties de l'image. La contribution clé est, finalement, une technique capable d'isoler les régions des images utiles pour une représentation locale. De plus, nous proposons une méthode nouvelle pour apprendre une représentation structurée des coefficients des réseaux de neurones. Nous présentons des résultats sur des jeux de données difficiles, ainsi que des comparaisons avec des méthodes concurrentes récentes. Nous prouvons que les méthodes proposées s'étendent à d'autres tâches de reconnaissance visuelles comme la classification d'objets, de scènes ou d'actions.

Download or read book Cognitive Remediation Therapy for Schizophrenia written by Professor Til Wykes and published by Routledge. This book was released on 2006-05-02 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Could CRT provide the first structured method of alleviating cognitive deficits associated with schizophrenia? Cognitive Remediation Therapy for Schizophrenia describes the background and development of this new psychological therapy and demonstrates how it provides the first structured help to overcome the thinking problems associated with schizophrenia. In three sections, the book covers the theoretical and empirical underpinning of cognitive remediation therapy and explores its application. Part I, 'The Development of Therapy', provides the historical context and theoretical background to the therapy and emphasizes the value of rehabilitating cognitive deficits. In Part II, 'Improving Cognitive Processes', the process and effects of changing cognition are examined. Finally, in Part III, 'The Process of Therapy', the authors provide a clinical guide to the delivery of cognitive remediation therapy and use case examples to support its efficacy. This book is the first to describe an individual cognitive remediation therapy programme based on a clear model of the relationship between thinking and behaviour. It will be of both academic and clinical value to all those health professionals and clinical academics who want not only to understand the relationships between thought and action but also to intervene to improve therapy.

Download or read book The Power of Interest for Motivation and Engagement written by K Ann Renninger and published by Routledge. This book was released on 2015-11-19 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Power of Interest for Motivation and Engagement describes the benefits of interest for people of all ages. Using case material as illustrations, the volume explains that interest can be supported to develop, and that the development of a person's interest is always motivating and results in meaningful engagement. This volume is written for people who would like to know more about the power of their interests and how they could develop them: students who want to be engaged, educators and parents wondering about how to facilitate motivation, business people focusing on ways in which they could engage their employees and associates, policy-makers whose recognition of the power of interest may lead to changes resulting in a new focus supporting interest development for schools, out of school activity, industry, and business, and researchers studying learning and motivation. It draws on research in cognitive, developmental, educational, and social psychology, as well as in the learning sciences, and neuroscience to demonstrate that there is power for everyone in leveraging interest for motivation and engagement.

Download or read book The Future of the Mind written by Michio Kaku and published by Anchor. This book was released on 2015-02-17 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Michio Kaku, the New York Times bestselling author of Physics of the Impossible and Physics of the Future tackles the most fascinating and complex object in the known universe: the human brain. The Future of the Mind brings a topic that once belonged solely to the province of science fiction into a startling new reality. This scientific tour de force unveils the astonishing research being done in top laboratories around the world—all based on the latest advancements in neuroscience and physics—including recent experiments in telepathy, mind control, avatars, telekinesis, and recording memories and dreams. The Future of the Mind is an extraordinary, mind-boggling exploration of the frontiers of neuroscience. Dr. Kaku looks toward the day when we may achieve the ability to upload the human brain to a computer, neuron for neuron; project thoughts and emotions around the world on a brain-net; take a “smart pill” to enhance cognition; send our consciousness across the universe; and push the very limits of immortality.

Download or read book Staying with the Trouble written by Donna J. Haraway and published by Duke University Press. This book was released on 2016-08-25 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the midst of spiraling ecological devastation, multispecies feminist theorist Donna J. Haraway offers provocative new ways to reconfigure our relations to the earth and all its inhabitants. She eschews referring to our current epoch as the Anthropocene, preferring to conceptualize it as what she calls the Chthulucene, as it more aptly and fully describes our epoch as one in which the human and nonhuman are inextricably linked in tentacular practices. The Chthulucene, Haraway explains, requires sym-poiesis, or making-with, rather than auto-poiesis, or self-making. Learning to stay with the trouble of living and dying together on a damaged earth will prove more conducive to the kind of thinking that would provide the means to building more livable futures. Theoretically and methodologically driven by the signifier SF—string figures, science fact, science fiction, speculative feminism, speculative fabulation, so far—Staying with the Trouble further cements Haraway's reputation as one of the most daring and original thinkers of our time.
