Book Synopsis Alternating Projection Methods by : Ren Escalante
Download or read book Alternating Projection Methods written by Ren Escalante. This book was released on 2011-01-01. Available in PDF, EPUB and Kindle. Book excerpt: This book describes and analyzes all available alternating projection methods for solving the general problem of finding a point in the intersection of several given sets belonging to a Hilbert space. For each method the authors describe and analyze convergence, speed of convergence, acceleration techniques, stopping criteria, and applications. Different types of algorithms and applications are studied for subspaces, linear varieties, and general convex sets. The authors also unify these algorithms into a common theoretical framework. The book provides readers with the theoretical and practical aspects of the most relevant alternating projection methods in a single accessible source; it gives several acceleration techniques for every method it presents and analyzes, including schemes that cannot be found in other books; and it provides full descriptions of several important mathematical problems and specific applications for which the alternating projection methods represent an efficient option including examples and problems that illustrate this material.

Book Synopsis Projectors and Projection Methods by : Aurél Galántai
Download or read book Projectors and Projection Methods written by Aurél Galántai. This book was released on 2013-12-11. Available in PDF, EPUB and Kindle. Book excerpt: The projectors are considered as simple but important type of matrices and operators. Their basic theory can be found in many books, among which Hal mas [177], [178] are of particular significance. The projectors or projections became an active research area in the last two decades due to ideas generated from linear algebra, statistics and various areas of algorithmic mathematics. There has also grown up a great and increasing number of projection meth ods for different purposes. The aim of this book is to give a unified survey on projectors and projection methods including the most recent results. The words projector, projection and idempotent are used as synonyms, although the word projection is more common. We assume that the reader is familiar with linear algebra and mathemati cal analysis at a bachelor level. The first chapter includes supplements from linear algebra and matrix analysis that are not incorporated in the standard courses. The second and the last chapter include the theory of projectors. Four chapters are devoted to projection methods for solving linear and non linear systems of algebraic equations and convex optimization problems.

Book Synopsis Greedy Approximation by : Vladimir Temlyakov
Download or read book Greedy Approximation written by Vladimir Temlyakov. This book was released on 2011-09-08. Available in PDF, EPUB and Kindle. Book excerpt: This first book on greedy approximation gives a systematic presentation of the fundamental results. It also contains an introduction to two hot topics in numerical mathematics: learning theory and compressed sensing. Nonlinear approximation is becoming increasingly important, especially since two types are frequently employed in applications: adaptive methods are used in PDE solvers, while m-term approximation is used in image/signal/data processing, as well as in the design of neural networks. The fundamental question of nonlinear approximation is how to devise good constructive methods (algorithms) and recent results have established that greedy type algorithms may be the solution. The author has drawn on his own teaching experience to write a book ideally suited to graduate courses. The reader does not require a broad background to understand the material. Important open problems are included to give students and professionals alike ideas for further research.
