Nonnegative matrix factorization (NMF) in its modern form has become a standard tool in the analysis of high-dimensional data sets. This book provides a comprehensive and up-to-date account of the most important aspects of the NMF problem and is the first to detail its theoretical aspects, including geometric interpretation, nonnegative rank, complexity, and uniqueness. It explains why understanding these theoretical insights is key to using this computational tool effectively and meaningfully. Nonnegative Matrix Factorization is accessible to a wide audience and is ideal for anyone interested in the workings of NMF. It discusses some new results on the nonnegative rank and the identifiability of NMF and makes available MATLAB codes for readers to run the numerical examples presented in the book. Graduate students starting to work on NMF and researchers interested in better understanding the NMF problem and how they can use it will find this book useful. It can be used in advanced undergraduate and graduate-level courses on numerical linear algebra and on advanced topics in numerical linear algebra and requires only a basic knowledge of linear algebra and optimization.

It is widely recognized that internet technology has had a profound effect on political participation in China, but this new use of technology is not unprecedented in Chinese history. This is a pioneering work that systematically describes and analyzes the manner in which the Chinese used telegraphy during the late Qing, and the internet in the contemporary period, to participate in politics. Drawing upon insights from the fields of anthropology, history, political science, and media studies, this book historicizes the internet in China and may change the direction of the emergent field of Chinese internet studies. In contrast to previous works, this book is unprecedented in its perspective, in the depth of information and understanding, in the conclusions it reaches, and in its methodology. Written in a clear and engaging style, this book is accessible to a broad audience.

The growth in popularity and complexity of video games has spurred new interest in how games are developed and in the research and technology behind them. David Heineman brings together some of the most iconic, influential, and interesting voices from across the gaming industry and asks them to weigh in on the past, present, and future of video games. Among them are legendary game designers Nolan Bushnell (Pong) and Eugene Jarvis (Defender), who talk about their history of innovations from the earliest days of the video game industry through to the present; contemporary trailblazers Kellee Santiago (Journey) and Casey Hudson (Mass Effect), who discuss contemporary relationships between those who create games and those who play them; and scholars Ian Bogost (How to Do Things With Videogames) and Edward Castronova (Exodus to the Virtual World), who discuss how to research and write about games in ways that engage a range of audiences. These experts and others offer fascinating perspectives on video games, game studies, gaming culture, and the game industry more broadly.

Rapidly growing cognitive technologies (such as word processors, web browsers, cell phones, and personal data assistants) aid learning, memory, and problem solving, and contribute to every part of modern life from interviewing crime witnesses to learning a foreign language to calling one's mother. This collection of essays on cognitive technology examines the interaction between the human mind and the tools people create to enhance it, studying which technologies assist cognition the most and what features are most effective. It also considers the point at which the technological enhancement of human ability begins to restrict that very ability, such as the risk of some cognitive technologies impairing cognition or creating disadvantages for individuals or groups. This collection of 11 essays discusses the most recent psychological research in cognitive technology, showcasing the paradigms and theories that have driven the development of new cognitive technologies. It explores the impact of technology on cognitive psychology, the classroom, and social interaction and group problem solving. Topics covered include the distracting characteristics of new technologies (such as the effects of cell phone use on driving ability and of distracting advertisements on problem solving), the study of mass media through assessing memories for media experiences, the media's role in advancing gender and racial prejudices, and the misuse of cognitive technology through identity theft and cyberterrorism. Each essay concludes with a bibliography.

The prefix "hyper" refers to multiplicity and abundance. More than a physical space, a hypercity is a real city overlaid with information networks that document the past, catalyze the present, and project future possibilities. Hypercities are always under construction. Todd Presner, David Shepard, and Yoh Kawano put digital humanities theory into practice to chart the proliferating cultural records of places around the world. A digital platform transmogrified into a book, it explains the ambitious online project of the same name that maps the historical layers of city spaces in an interactive, hypermedia environment. The authors examine the media archaeology of Google Earth and the cultural-historical meaning of map projections, and explore recent events-the "Arab Spring" and the Fukushima nuclear power plant disaster-through social media mapping that incorporates data visualizations, photographic documents, and Twitter streams. A collaboratively authored and designed work, HyperCities includes a "ghost map" of downtown Los Angeles, polyvocal memory maps of LA's historic Filipinotown, avatar-based explorations of ancient Rome, and hour-by-hour mappings of the Tehran election protests of 2009. Not a book about maps in the literal sense, HyperCities describes thick mapping: the humanist project of participating and listening that transforms mapping into an ethical undertaking. Ultimately, the digital humanities do not consist merely of computer-based methods for analyzing information. They are a means of integrating scholarship with the world of lived experience, making sense of the past in the layered spaces of the present for the sake of the open future.

Industrial innovation is essential for national and corporate competitiveness. Understanding the nature, determinants and consequences of innovation is a key task of managers, public policymakers and all students of industry and business. This major new reference book brings together specially commissioned contributions by many leading world experts on a wide range of issues concerning innovation. The first section provides an introduction to the significance and process of industrial innovation, and to the contexts or 'systems' within which it occurs. A series of sectoral and industrial studies is followed by assessments of the key issues affecting innovation. Another section examines one of the main constraints on successful innovation: the strategic management of technology in both products and processes. As well as the benefits of innovation, the problems and challenges of the processes, management and outcomes of innovation are raised throughout the book. Select bibliographies chosen by international experts are included to ensure that this comprehensive reference tool is an indispensable guide for students, scholars, innovators and policymakers.

Teaches readers to identify and avoid deceit and misinformation online. We are commonly deceived by numbers in our everyday lives. From lotteries, product warranties, and weight loss fads to misleading headlines, numbers are used in manipulative ways to lure us into making decisions about our life. Data Duped will help you avoid common pitfalls and develop a sense of ‘data defense’ by learning what types of questions to ask and how to maintain a healthy level of curiosity and data skepticism. Data Duped gives readers a super power, or at least we hope so. Knowledge is power. With knowledge of how data can be manipulated, how it can influence our decisions and how it can deceive, readers will face data with a new empowered approach. This book purposefully raises more questions than answers and guides readers to seek the differences between the plausible and the ridiculous along a journey of informed critical thinking and data literacy. With historical parallels and both practical and relatable examples, readers will learn how to separate the ‘malarkey’ from the truth, become able to comfortably bring a little more data into their lives, and ultimately avoid being hoodwinked by misinformation.
