Khinchin. Comprehensive, rigorous introduction to work of Shannon, McMillan, Feinstein and Khinchin. Translated by R. A. Silverman and M. D. Friedman.
This extraordinary three-volume work, written in an engaging and rigorous style by a world authority in the field, provides an accessible, comprehensive introduction to the full spectrum of mathematical and statistical techniques underpinning contemporary methods in data-driven learning and inference. This second volume, Inference, builds on the foundational topics established in volume I to introduce students to techniques for inferring unknown variables and quantities, including Bayesian inference, Monte Carlo Markov Chain methods, maximum-likelihood estimation, hidden Markov models, Bayesian networks, and reinforcement learning. A consistent structure and pedagogy is employed throughout this volume to reinforce student understanding, with over 350 end-of-chapter problems (including solutions for instructors), 180 solved examples, almost 200 figures, datasets and downloadable Matlab code. Supported by sister volumes Foundations and Learning, and unique in its scale and depth, this textbook sequence is ideal for early-career researchers and graduate students across many courses in signal processing, machine learning, statistical analysis, data science and inference.

Foreword by Professor Annemaree Lloyd, Swedish School of Library and Information Science, University of Boras Today's society is characterized by quick technological developments and constant changes to our information environments. One of the biggest changes has been on our workplace environments where technological developments have automated work processes that were previously done by manual labour whilst new professions and work tasks have emerged in response to new methods of creating, sharing and using information. Information at Work: Information management in the workplace provides a comprehensive account of information in the modern workplace. It includes a set of chapters examining and reviewing the major concepts within workplace information, from over-arching themes of information cultures and ecologies, to strategic concerns of information management and governance, and to detailed accounts of questions and current debates. This book will be useful reading for researchers in Information Science and Information Management and students on related courses. It is also suitable to be used as an introductory text for those working in allied fields such as Management and Business Studies.
Whilst a great deal of progress has been made in recent decades, concerns persist about the course of the social sciences. Progress in these disciplines is hard to assess and core scientific goals such as discovery, transparency, reproducibility, and cumulation remain frustratingly out of reach. Despite having technical acumen and an array tools at their disposal, today's social scientists may be only slightly better equipped to vanquish error and construct an edifice of truth than their forbears - who conducted analyses with slide rules and wrote up results with typewriters. This volume considers the challenges facing the social sciences, as well as possible solutions. In doing so, we adopt a systemic view of the subject matter. What are the rules and norms governing behavior in the social sciences? What kinds of research, and which sorts of researcher, succeed and fail under the current system? In what ways does this incentive structure serve, or subvert, the goal of scientific progress?
Discover the very latest game-theoretic approaches for designing, modeling, and optimizing emerging wireless communication networks and systems with this unique text. Providing a unified and comprehensive treatment throughout, it explains basic concepts and theories for designing novel distributed wireless networking mechanisms, describes emerging game-theoretic tools from an engineering perspective, and provides an extensive overview of recent applications. A wealth of new tools is covered - including matching theory and games with bounded rationality - and tutorial chapters show how to use these tools to solve current and future wireless networking problems in areas such as 5G networks, network virtualization, software defined networks, cloud computing, the Internet of Things, context-aware networks, green communications, and security. This is an ideal resource for telecommunications engineers, and researchers in industry and academia who are working on the design of efficient, scalable, and robust communication protocols for future wireless networks, as well as graduate students in these fields.
This is the second of six volumes in a series of selected scientific papers by one of the world's most distinguished economists. Volume I presented the basic concepts in the Economics of Information, showing that markets in which information was imperfect or asymmetric (where some individuals know things that others don't) behave markedly different from how they would if information were perfect. Volume II, with papers written between 1969 and 2009, explores the implications of the New Information Paradigm for labor, capital, and product markets. This New Paradigm, for which Stiglitz was awarded the Nobel Memorial Prize in Economics in 2001, has fundamentally changed the way we think about every aspect of economics, raising new questions on corporate governance, and leading us to reconsider old questions on corporate finance, the relationship between finance and the economy, and the theory of economic incentives. While this volume focuses on the application of basic principles, it also extends the theory in important ways, showing the fruitfulness of Stiglitz's research strategy. In doing so, the papers set the ground for questioning some prevailing doctrines: key market phenomena cannot be explained by markets with rational expectations, even when information is imperfect. It demonstrates that how societies organize the obtainment, processing, and transmitting of information is as important as how they organize the production and distribution of goods. Indeed, the two issues are inseparable. The papers thus lay the foundations of a New Institutional Economics, not only describing how institutions (like sharecropping or banks) work and affect resource allocations, but why they arise and take on particular forms.
The production and consumption of Information and Communication
Technologies (or ICTs) has become embedded within our societies.
The influence and implications of this have an impact at a macro
level, in the way our governments, economies, and businesses
operate, and in our everyday lives. This handbook is about the many
challenges presented by ICTs. It sets out an intellectual agenda
that examines the implications of ICTs for individuals,
organizations, democracy, and the economy.
Information is a key issuein decision making in economics and
business. Being 'in the know' confers strategic advantages to
people, allowing them to lie and/or cheat on their uninformed
opponents. However, itis possible that all sides end up worse off
in such situations, compared with the likely outcome under full
information. This new text is designed to take students through the key
issues to give an understanding of the impact of imperfect and
asymmetric information in an economic context. At each stage Molho
analyses and explains the key points using clear models that set
the outcome under imperfect information against that under full
information. The book is divided into four major sections
covering: Each section also covers experimental studies that test the predictions of theory. This text is aimed mainly at undergraduate students and gives an accessible introduction to this crucial area of economic theory.

Luciano Floridi develops an original ethical framework for dealing with the new challenges posed by Information and Communication Technologies (ICTs). ICTs have profoundly changed many aspects of life, including the nature of entertainment, work, communication, education, health care, industrial production and business, social relations, and conflicts. They have had a radical and widespread impact on our moral lives and on contemporary ethical debates. Privacy, ownership, freedom of speech, responsibility, technological determinism, the digital divide, and pornography online are only some of the pressing issues that characterise the ethical discourse in the information society. They are the subject of Information Ethics (IE), the new philosophical area of research that investigates the ethical impact of ICTs on human life and society. Since the seventies, IE has been a standard topic in many curricula. In recent years, there has been a flourishing of new university courses, international conferences, workshops, professional organizations, specialized periodicals and research centres. However, investigations have so far been largely influenced by professional and technical approaches, addressing mainly legal, social, cultural and technological problems. This book is the first philosophical monograph entirely and exclusively dedicated to it. Floridi lays down, for the first time, the conceptual foundations for IE. He does so systematically, by pursuing three goals: a) a metatheoretical goal: it describes what IE is, its problems, approaches and methods; b) an introductory goal: it helps the reader to gain a better grasp of the complex and multifarious nature of the various concepts and phenomena related to computer ethics; c) an analytic goal: it answers several key theoretical questions of great philosophical interest, arising from the investigation of the ethical implications of ICTs. Although entirely independent of The Philosophy of Information (OUP, 2011), Floridi's previous book, The Ethics of Information complements it as new work on the foundations of the philosophy of information.

Andre Koehler entwickelt eine Architektur fur den intelligenten Geschaftsdatenaustausch (IDI), die es Unternehmen ermoeglicht, strukturierte Geschaftsdokumente ad hoc und mit unbekannten Partnern austauschen zu koennen. Zentrale Bestandteile dieser Architektur sind Ontologien und semantische Matchingverfahren, die von sogenannten IDI-Agenten zur Interpretation von Geschaftsdokumenten sowie zur Protokollvereinbarung genutzt werden.
Die Autoren diskutieren die Problematik der Datenqualitat, und entwickeln ein webbasiertes Werkzeug, welches die Integration der Daten ermoglicht und die Qualitat der Datenbestande testet. Die Analyse der Bestande, das Auffinden von Duplikaten und die Bereinigung der Daten stehen dabei im Fokus dieses Werkzeuges, welches eine Grundlage fur eine umfassende Datenqualitats- und Bereinigungslosung darstellen kann."
Kryptografie hat sich in jungster Zeit als eine Wissenschaft gezeigt, bei der mathematische Methoden mit besonderem Erfolg eingesetzt werden konnen. Das Buch stellt die gesamte Kryptografie unter diesem Aspekt vor: Grundlagen und Anwendungen, Verschlusselung und Authentifikation, symmetrische Algorithmen und Public-Key-Verfahren werden entsprechend ihrer Wichtigkeit prasentiert. Das Buch hat den Umfang einer 2-semestrigen Vorlesung, aufgrund seiner klaren Darstellung eignet es sich aber auch hervorragend zum Selbststudium. Zahlreiche Ubungsaufgaben von unterschiedlichem Schwierigkeitsgrad dienen zur Kontrolle des Verstandnisses."
Mit Erfindung der Schrift entstand gleichzeitig der Bedarf, Geschriebenes vor unbefugten Lesern zu verbergen. Die Lehre von den Geheimschriften ist daher fast ebenso alt wie die Schrift selbst. Als Wissenschaft im modernen Sinne ist die Kryptographie jedoch noch sehr jung. 1994 erfanden Naor und Shamir folgendes Verfahren: Sie verteilten ein Bild so auf zwei Folien, dass auf jeder einzelnen Folie nur ein zufalliges Punktmuster zu sehen ist, aber beide Folien ubereinander gelegt ein geheimes Bild ergeben. Das Buch gibt einen Einblick in die aktuelle Forschung, wobei es bewusst auf Hoehere Mathematik verzichtet. Es eignet sich daher ideal als Grundlage fur Proseminare und Mathematik-AGs der Sekundarstufe. Plus: Aufgaben mit Musterloesungen.
Information und Codierung sind Schlusselbegriffe der modernen
Informationstechnik. Dieses Buch gibt dazu eine fundierte
Einfuhrung in Grundlagen und Anwendungen. Ausser der ublichen
Oberstufenmathematik (Vektor- und Matrizenrechnung, elementare
Wahrscheinlichkeitsrechung) werden keine besonderen Vorkenntnisse
vorausgesetzt. Durch zahlreiche Bilder, Beispiele und geloste
Aufgaben, sowie Hinweise auf Anwendungen wird die selbstandige
Erarbeitung des Lehrstoffes unterstutzt.
Modulationsverfahren, Codierungstechniken und Kryptologie sind eng
verwandte Gebiete. Das vorliegende Lehrbuch stellt sie mit ihren
Verzahnungen thematisch umfassend, methodisch genau und
mathematisch verstandlich dar. Ausgehend von einer Einfuhrung in
die Informationstheorie werden Themen behandelt, deren Kenntnis fur
die systematische Analyse von Systemen zur Informationsubertragung
notwendig ist. Dazu gehoren die Quellen- und Kanalcodierung, die
analogen und digitalen Modulationsverfahren sowie die Beschreibung
von stochastischen Prozessen. Das Buch wird durch eine ausgedehnte
Einfuhrung in die Kryptologie abgerundet, in der neben den
gebrauchlichsten Algorithmen auch die wichtigsten Protokolle
vorgestellt und analysiert werden. Besonderer Wert wurde darauf
gelegt, modernen Verfahren wie z.B. Turbo Codes, OFDM, Elliptische
Kurven oder auch die Quantenkryptographie einzubeziehen. |
