Nearest-Neighbor Methods in Learning and Vision: Theory and Practice by Gregory Shakhnarovich

Recent advances in computational geometry and machine learning,MoreRegression and classification methods based on similarity of the input to stored examples have not been widely used in applications involving very large sets of high-dimensional data. Recent advances in computational geometry and machine learning, however, may alleviate the problems in using these methods on large data sets. This volume presents theoretical and practical discussions of nearest-neighbor NN methods in machine learning and examines computer vision as an application domain in which the benefit of these advanced methods is often dramatic. It brings together contributions from researchers in theory of computation, machine learning, and computer vision with the goals of bridging the gaps between disciplines and presenting state-of-the-art methods for emerging applications. The contributors focus on the importance of designing algorithms for NN search, and for the related classification, regression, and retrieval tasks, that remain efficient even as the number of points or the dimensionality of the data grows very large.

I also hold a part-time faculty appointment at the University of Chicago Department of Computer Science. Please contact me for details. My thesis topic was Learning Task-Specific Similarity. Jiang, G. Larsson, M. Maire, G.

Nearest neighbor search NNS , as a form of proximity search , is the optimization problem of finding the point in a given set that is closest or most similar to a given point. Closeness is typically expressed in terms of a dissimilarity function: the less similar the objects, the larger the function values. Donald Knuth in vol. A direct generalization of this problem is a k -NN search, where we need to find the k closest points. Most commonly M is a metric space and dissimilarity is expressed as a distance metric , which is symmetric and satisfies the triangle inequality. Even more common, M is taken to be the d -dimensional vector space where dissimilarity is measured using the Euclidean distance , Manhattan distance or other distance metric. However, the dissimilarity function can be arbitrary.

Okay, it shuffled past the half open door and continued up the stairs, the outdated tags on her van were stolen and she lived somewhere around here, you need to die? In both cases, the input consists of the k closest training examples in the feature output depends on whether k-NN is used for classification or regression:. In k-NN classification, the output is a class membership. He was one of those babies who looked like a grizzled old man, and her eyes the soulless blue-gray of a winter river. I could not hear what was happening below me-the voices were too soft to distinguish-and so, near Klessheim, for there was only a narrow path between the Scylla and Charybdis of their becoming either heartless ruffians unable any longer to treasure human life.

Nearest neighbor NN methods, that is regression and classification methods based on similarity of the input to stored examples, have been known and used for decades. The book presents a suite of recent results and techniques aimed to extending the range of problems for which nearest neighbor methods are tractable. Shakhnarovich, T.

Кульминация развития докомпьютерного шифрования пришлась на время Второй мировой войны. Нацисты сконструировали потрясающую шифровальную машину, которую назвали Энигма. Она была похожа на самую обычную старомодную пишущую машинку с медными взаимосвязанными роторами, вращавшимися сложным образом и превращавшими открытый текст в запутанный набор на первый взгляд бессмысленных групп знаков.

Фонтейн тотчас повернулся к стене-экрану. Пятнадцать секунд спустя экран ожил. Сначала изображение на экране было смутным, точно смазанным сильным снегопадом, но постепенно оно становилось все четче и четче. Это была цифровая мультимедийная трансляция - всего пять кадров в секунду. На экране появились двое мужчин: один бледный, коротко стриженный, другой - светловолосый, с типично американской внешностью.

 Данные? - спросил Бринкерхофф.  - Какие такие данные. Танкадо отдал кольцо. Вот и все доказательства. - Агент Смит, - прервал помощника директор.
