This book was released on 2016-07-21 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientific Essay from the year 2015 in the subject Mathematics - Miscellaneous, language: English, abstract: Representation of two dimensional objects into one dimensional space is simple and efficient when using a two coordinate system imposed upon a grid. However, when the two dimensions are expanded far beyond visual and sometimes mental understanding, techniques are used to quantify and simplify the representation of such objects. These techniques center around spatial interpretations by means of a space-filling curve. Since the late 1800's, mathematicians and computer scientists have succeeded with algorithms that express high dimensional geometries. However, very few implementations of the algorithms beyond three dimensions for computing these geometries exist. We propose using the basic spatial computations developed by pioneers in the field like G. Peano, D. Hilbert, E. H. Moore, and others in a working model. The algorithms in this paper are fully implemented in high-level programming languages utilizing a relation database management system. We show the execution speeds of the algorithms using a space-filling curve index for searching compared to brute force searching. Finally, we contrast three space-filling curve algorithms: Moore, Hilbert, and Morton, in execution time of searching for high dimensional data in point queries and range queries.
Book Synopsis High-Dimensional Indexing by : Cui Yu
Download or read book High-Dimensional Indexing written by Cui Yu and published by Springer. This book was released on 2003-08-01 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this monograph, we study the problem of high-dimensional indexing and systematically introduce two efficient index structures: one for range queries and the other for similarity queries. Extensive experiments and comparison studies are conducted to demonstrate the superiority of the proposed indexing methods. Many new database applications, such as multimedia databases or stock price information systems, transform important features or properties of data objects into high-dimensional points. Searching for objects based on these features is thus a search of points in this feature space. To support efficient retrieval in such high-dimensional databases, indexes are required to prune the search space. Indexes for low-dimensional databases are well studied, whereas most of these application specific indexes are not scaleable with the number of dimensions, and they are not designed to support similarity searches and high-dimensional joins.

Book Synopsis R-tree Index Optimization by : D. M. Gavrila
Download or read book R-tree Index Optimization written by D. M. Gavrila and published by . This book was released on 1994 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "The optimization of spatial indexing is an increasingly important issue considering the fact that spatial databases, in such diverse areas as geographical, CAD/CAM and image applications, are growing rapidly in size and often contain on the order of millions of items or more. This necessitates the storage of the index on disk, which has the potential of slowing down the access time significantly. In this paper, we discuss ways of minimizing the disk access frequency by grouping together data items which are close to one another in the spatial domain ('packing'). The data structure which we seek to optimize here is the R- tree for a given set of data objects. Existing methods of building an R- tree index based on space-filling curves (Peano, Hilbert) are computationally cheap, but they do not preserve spatial locality well, in particular when dealing with higher-dimensional data of non-zero extent. On the other hand, existing methods of packing based on all dimensions of the data, such as the several proposed dynamic R-tree insertion algorithms, do not take advantage of the fact that all the data objects are known beforehand. Furthermore, they are essentially serial in nature. In this paper, we regard packing as an optimization problem and propose an iterative method of finding a close-to-optimal solution to the packing of a given set of spatial objects in D dimensions. The method achieves a high degree of parallelism by constructing the R-tree bottom-up. In experiments on data of various dimensionalities and distributions, we have found that the proposed method can significantly improve on the packing performance of the R* insertion algorithm and the Hilbert curve. It is shown that the improvements increase with the skewness of the data and, in some cases, can even amount to an order of magnitude in terms of decreased response time."

Book Synopsis Spatial Data Management by : Nikos Mamoulis
Download or read book Spatial Data Management written by Nikos Mamoulis and published by Morgan & Claypool Publishers. This book was released on 2012 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spatial database management deals with the storage, indexing, and querying of data with spatial features, such as location and geometric extent. Many applications require the efficient management of spatial data, including Geographic Information Systems, Computer Aided Design, and Location Based Services. The goal of this book is to provide the reader with an overview of spatial data management technology, with an emphasis on indexing and search techniques. It first introduces spatial data models and queries and discusses the main issues of extending a database system to support spatial data. It presents indexing approaches for spatial data, with a focus on the R-tree. Query evaluation and optimization techniques for the most popular spatial query types (selections, nearest neighbor search, and spatial joins) are portrayed for data in Euclidean spaces and spatial networks. The book concludes by demonstrating the ample application of spatial data management technology on a wide range of related application domains: management of spatio-temporal data and high-dimensional feature vectors, multi-criteria ranking, data mining and OLAP, privacy-preserving data publishing, and spatial keyword search. Table of Contents: Introduction / Spatial Data / Indexing / Spatial Query Evaluation / Spatial Networks / Applications of Spatial Data Management Technology

Book Synopsis Handbook of Data Structures and Applications by : Dinesh P. Mehta
Download or read book Handbook of Data Structures and Applications written by Dinesh P. Mehta and published by CRC Press. This book was released on 2004-10-28 with total page 1387 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although there are many advanced and specialized texts and handbooks on algorithms, until now there was no book that focused exclusively on the wide variety of data structures that have been reported in the literature. The Handbook of Data Structures and Applications responds to the needs of students, professionals, and researchers who need a mainstream reference on data structures by providing a comprehensive survey of data structures of various types. Divided into seven parts, the text begins with a review of introductory material, followed by a discussion of well-known classes of data structures, Priority Queues, Dictionary Structures, and Multidimensional structures. The editors next analyze miscellaneous data structures, which are well-known structures that elude easy classification. The book then addresses mechanisms and tools that were developed to facilitate the use of data structures in real programs. It concludes with an examination of the applications of data structures. The Handbook is invaluable in suggesting new ideas for research in data structures, and for revealing application contexts in which they can be deployed. Practitioners devising algorithms will gain insight into organizing data, allowing them to solve algorithmic problems more efficiently.
