Informations- und Kodierungstheorie
€ 34.99 *
ggf. zzgl. Versand

Was ist Information? Wie kann man sie darstellen, sicher übertragen oder speichern? Viele Fragen, auf die das Buch Antworten gibt. Die Informationstheorie liefert die Grundlage für die Berechnung des Informationsgehalts von diskreten und kontinuierlichen Quellen und deren Darstellung in kodierter Form. So können erforderliche Speicher- und Kanalkapazitäten bei der Informationsverarbeitung und -übertragung in IT-Systemen bestimmt werden. Abschnitte im Kapitel Kanalkodierung wurden inhaltlich neu gestaltet und erweitert. Es zeigt Lösungen für eine sichere Informationsübertragung über gestörte Kanäle. Ausführlich werden Block- und blockfreie Kodes, serielle und parallele Kodeverkettungen mit hard decision- und (iterativer) soft decision-Dekodierung beschrieben, die zur Fehlererkennung und Fehlerkorrektur dienen. Der Inhalt Informationsquellen und deren Beschreibung - Kodierung diskreter Quellen - Nachrichten und Kanäle - Diskrete Kanäle - Analoge Kanäle - Quantisierung analoger Signale - Kanalkodierung und Fehlerkorrekturverfahren - Bewertung von Kanalkodes Die Zielgruppen Studierende der Informatik, Medieninformatik, Nachrichtentechnik, Mathematik an Universitäten und FachhochschulenInformatiklehrer und Praktiker Die Autoren Dr. Dagmar Schönfeld, TU Dresden Dr. Herbert Klimant, TU Dresden Dr. Rudi Piotraschke, TU Dresden

Information Theory
€ 20.99 *
ggf. zzgl. Versand

Originally developed by Claude Shannon in the 1940s, the theory of information laid the foundations for the digital revolution, and is now an essential tool in deep space communication, genetics, linguistics, data compression, and brain sciences. In this richly illustrated book, accessible examples are used to show how information theory can be understood in terms of everyday games like ´20 Questions´, and the simple MatLab programs provided give hands-on experience of information theory in action. Written in a tutorial style, with a comprehensive glossary, this text represents an ideal primer for novices who wish to become familiar with the basic principles of information theory.

Information Retrieval

Interested in how an efficient search engine works? Want to know what algorithms are used to rank resulting documents in response to user requests? The authors answer these and other key information retrieval design and implementation questions. This book is not yet another high level text. Instead, algorithms are thoroughly described, making this book ideally suited for both computer science students and practitioners who work on search-related applications. As stated in the foreword, this book provides a current, broad, and detailed overview of the field and is the only one that does so. Examples are used throughout to illustrate the algorithms. The authors explain how a query is ranked against a document collection using either a single or a combination of retrieval strategies, and how an assortment of utilities are integrated into the query processing scheme to improve these rankings. Methods for building and compressing text indexes, querying and retrieving documents in multiple languages, and using parallel or distributed processing to expedite the search are likewise described. This edition is a major expansion of the one published in 1998. Besides updating the entire book with current techniques, it includes new sections on language models, cross-language information retrieval, peer-to-peer processing, XML search, mediators, and duplicate document detection.

Quantum Information Theory
€ 58.99 *
ggf. zzgl. Versand

Developing many of the major, exciting, pre- and post-millennium developments from the ground up, this book is an ideal entry point for graduate students into quantum information theory. Significant attention is given to quantum mechanics for quantum information theory, and careful studies of the important protocols of teleportation, superdense coding, and entanglement distribution are presented. In this new edition, readers can expect to find over 100 pages of new material, including detailed discussions of Bell´s theorem, the CHSH game, Tsirelson´s theorem, the axiomatic approach to quantum channels, the definition of the diamond norm and its interpretation, and a proof of the Choi-Kraus theorem. Discussion of the importance of the quantum dynamic capacity formula has been completely revised, and many new exercises and references have been added. This new edition will be welcomed by the upcoming generation of quantum information theorists and the already established community of classical information theorists.

Introduction to Information Retrieval
€ 46.99 *
ggf. zzgl. Versand

Class-tested and coherent, this textbook teaches classical and web information retrieval, including web search and the related areas of text classification and text clustering from basic concepts. It gives an up-to-date treatment of all aspects of the design and implementation of systems for gathering, indexing, and searching documents; methods for evaluating systems; and an introduction to the use of machine learning methods on text collections. All the important ideas are explained using examples and figures, making it perfect for introductory courses in information retrieval for advanced undergraduates and graduate students in computer science. Based on feedback from extensive classroom experience, the book has been carefully structured in order to make teaching more natural and effective. Slides and additional exercises (with solutions for lecturers) are also available through the book´s supporting website to help course instructors prepare their lectures.
