Robust and Distributed Hypothesis Testing (Lecture Notes in Electrical Engineering #414)
by Gökhan GülThis book generalizes and extends the available theory in robust and decentralized hypothesis testing. In particular, it presents a robust test for modeling errors which is independent from the assumptions that a sufficiently large number of samples is available, and that the distance is the KL-divergence. Here, the distance can be chosen from a much general model, which includes the KL-divergence as a very special case. This is then extended by various means. A minimax robust test that is robust against both outliers as well as modeling errors is presented. Minimax robustness properties of the given tests are also explicitly proven for fixed sample size and sequential probability ratio tests. The theory of robust detection is extended to robust estimation and the theory of robust distributed detection is extended to classes of distributions, which are not necessarily stochastically bounded. It is shown that the quantization functions for the decision rules can also be chosen as non-monotone. Finally, the book describes the derivation of theoretical bounds in minimax decentralized hypothesis testing, which have not yet been known. As a timely report on the state-of-the-art in robust hypothesis testing, this book is mainly intended for postgraduates and researchers in the field of electrical and electronic engineering, statistics and applied probability. Moreover, it may be of interest for students and researchers working in the field of classification, pattern recognition and cognitive radio.

Rock • Paper • Pixels: How Our Need to Communicate Created a New Economy, Society, and Individual: What will be the Effects of Artificial Intelligence and Quantum Computing?
by Patrick AievoliThe purpose of this book is to avail faculty, and students of the many different innovations, events, effects, and back-stories equated with the advent of this new era of communications and its impact on our world. At our core we are a species that needs to communicate and to find a way to properly represent those messages. Since the beginning of recorded history mankind has always attempted to communicate and to keep track of its endeavors and accomplishments. Now by using interaction design and modern digital media it has become possible to present “our story” through many current and evocative platforms.As each generation comes of age this new method is being utilized in all areas of their communication choices. These new generations desire their communication at a different rate than its predecessors. They want their information Internet ready and interactive. They are involved in the immediate and that choice is not going away. Interactive media is here to stay and has new rules and new effects. It is changing our economies, our societies and especially us - as individuals.The main goal of this book is to help you see how it started, where it is going and how to be on the right side of this transformation. How to take your first steps in that new direction and how to understand the effects of this new form of communication while being aware of its abilities and its dangers.As a friend once said, “no matter how thin you slice it there are always two sides.”

Rogue Archives: Digital Cultural Memory and Media Fandom
by Abigail De KosnikThe task of archiving was once entrusted only to museums, libraries, and other institutions that acted as repositories of culture in material form. But with the rise of digital networked media, a multitude of self-designated archivists -- fans, pirates, hackers -- have become practitioners of cultural preservation on the Internet. These nonprofessional archivists have democratized cultural memory, building freely accessible online archives of whatever content they consider suitable for digital preservation. In Rogue Archives, Abigail De Kosnik examines the practice of archiving in the transition from print to digital media, looking in particular at Internet fan fiction archives.De Kosnik explains that media users today regard all of mass culture as an archive, from which they can redeploy content for their own creations. Hence, "remix culture" and fan fiction are core genres of digital cultural production. De Kosnik explores, among other things, the anticanonical archiving styles of Internet preservationists; the volunteer labor of online archiving; how fan archives serve women and queer users as cultural resources; archivists' efforts to attract racially and sexually diverse content; and how digital archives adhere to the logics of performance more than the logics of print. She also considers the similarities and differences among free culture, free software, and fan communities, and uses digital humanities tools to quantify and visualize the size, user base, and rate of growth of several online fan archives.

Role of IT- ITES in Economic Development of Asia: Issues of Growth, Sustainability and Governance
by Soumyen Sikdar Ramesh Chandra Das Rajib BhattacharyyaThis book focuses on the contribution of Information Technology (IT) and Information Technology Enabled Services (ITES) in shaping the current and future global economic scenario, with a special focus on Asia, and taking into account the three broad macroeconomic dimensions — growth, sustainability and governance mechanisms. The last two decades have witnessed a structural shift in the world economy due to the tremendous growth in gross domestic product share for the service sector; in fact, service has emerged as the dominant sector and the main driver of GDP growth. This is mainly attributable to the spectacular success of the IT sector in the new knowledge economy. Tradability, technology and transportability – the three T’s – govern productivity growth in today’s services. Growing Asian economies such as India, China and Vietnam, using their demographic advantages, have been reaping the benefits of this boom. The book’s content focuses on recent debates and discussions concerning the issue of long-term sustainability and governance, especially in India, as these companies are facing continuous challenges in terms of international competition, salary inflation, health hazards, scarcity of talent, employee attrition, security concerns, global slowdown and many other technology-related issues. The book further highlights how the increased application of IT-based products and services is resulting in harsh inequalities concerning income distribution in many developing countries of Asia, mainly because of its labor shedding nature, and hence might be detrimental to sustainable development, if suitable policy measures are not implemented to counter these effects. The book provides a wealth of information for researchers, graduate students and political scientists alike, as well as thought-provoking insights for social scientists, policymakers and government officials. It also offers a valuable source of data for business and management professionals, and for members of Chambers of Commerce and Industry.

Roles, Trust, and Reputation in Social Media Knowledge Markets
by Sorin Adam Matei Elisa BertinoKnowledge and expertise, especially of the kind that can shape public opinion, have been traditionally the domain of individuals holding degrees awarded by higher learning institutions or occupying formal positions in notable organizations. Expertise is validated by reputations established in an institutionalized marketplace of ideas with a limited number of "available seats" and a stringent process of selection and retention of names, ideas, topics and facts of interest. However, the social media revolution, which has enabled over two billion Internet users not only to consume, but also to produce information and knowledge, has created a secondary and very active informal marketplace of ideas and knowledge. Anchored by platforms like Wikipedia, YouTube, Facebook and Twitter, this informal marketplace has low barriers to entry and has become a gigantic and potentially questionable, knowledge resource for the public at large. Roles, Trust and Reputation in Social Media Knowledge Markets will discuss some of the emerging trends in defining, measuring and operationalizing reputation as a new and essential component of the knowledge that is generated and consumed online. The book will propose a future research agenda related to these issues. The ultimate goal of research agenda being to shape the next generation of theoretical and analytic strategies needed for understanding how knowledge markets are influenced by social interactions and reputations built around functional roles. The authors, including leading scholars and young innovators, will share with the readers some of the main lessons they have learned from their own work in these areas and will discuss the issues, topics and sub-areas that they find under-studied or that promise the greatest intellectual payoff in the future. The discussion will be placed in the context of social network analysis and "big data" research. Roles, Trust and Reputation in Social Media Knowledge Markets exposes issues that have not been satisfactorily dealt with in the current literature, as the research agenda in reputation and authorship is still emerging. In a broader sense, the volume aims to change the way in which knowledge generation in social media spaces is understood and utilized. The tools, theories and methodologies proposed by the contributors offer concrete avenues for developing the next generation of research strategies and applications that will help: tomorrow's information consumers make smarter choices, developers to create new tools and researchers to launch new research programs.
