Coherence: In Signal Processing and Machine Learning
by David Ramírez Ignacio Santamaría Louis ScharfThis book organizes principles and methods of signal processing and machine learning into the framework of coherence. The book contains a wealth of classical and modern methods of inference, some reported here for the first time. General results are applied to problems in communications, cognitive radio, passive and active radar and sonar, multi-sensor array processing, spectrum analysis, hyperspectral imaging, subspace clustering, and related. The reader will find new results for model fitting; for dimension reduction in models and ambient spaces; for detection, estimation, and space-time series analysis; for subspace averaging; and for uncertainty quantification. Throughout, the transformation invariances of statistics are clarified, geometries are illuminated, and null distributions are given where tractable. Stochastic representations are emphasized, as these are central to Monte Carlo simulations. The appendices contain a comprehensive account of matrix theory, the SVD, the multivariate normal distribution, and many of the important distributions for coherence statistics. The book begins with a review of classical results in the physical and engineering sciences where coherence plays a fundamental role. Then least squares theory and the theory of minimum mean-squared error estimation are developed, with special attention paid to statistics that may be interpreted as coherence statistics. A chapter on classical hypothesis tests for covariance structure introduces the next three chapters on matched and adaptive subspace detectors. These detectors are derived from likelihood reasoning, but it is their geometries and invariances that qualify them as coherence statistics. A chapter on independence testing in space-time data sets leads to a definition of broadband coherence, and contains novel applications to cognitive radio and the analysis of cyclostationarity. The chapter on subspace averaging reviews basic results and derives an order-fitting rule for determining the dimension of an average subspace. These results are used to enumerate sources of acoustic and electromagnetic radiation and to cluster subspaces into similarity classes. The chapter on performance bounds and uncertainty quantification emphasizes the geometry of the Cramèr-Rao bound and its related information geometry.
Cohesive Subgraph Search Over Large Heterogeneous Information Networks (SpringerBriefs in Computer Science)
by Yixiang Fang Kai Wang Xuemin Lin Wenjie ZhangThis SpringerBrief provides the first systematic review of the existing works of cohesive subgraph search (CSS) over large heterogeneous information networks (HINs). It also covers the research breakthroughs of this area, including models, algorithms and comparison studies in recent years. This SpringerBrief offers a list of promising future research directions of performing CSS over large HINs.The authors first classify the existing works of CSS over HINs according to the classic cohesiveness metrics such as core, truss, clique, connectivity, density, etc., and then extensively review the specific models and their corresponding search solutions in each group. Note that since the bipartite network is a special case of HINs, all the models developed for general HINs can be directly applied to bipartite networks, but the models customized for bipartite networks may not be easily extended for other general HINs due to their restricted settings. The authors also analyze and compare these cohesive subgraph models (CSMs) and solutions systematically. Specifically, the authors compare different groups of CSMs and analyze both their similarities and differences, from multiple perspectives such as cohesiveness constraints, shared properties, and computational efficiency. Then, for the CSMs in each group, the authors further analyze and compare their model properties and high-level algorithm ideas.This SpringerBrief targets researchers, professors, engineers and graduate students, who are working in the areas of graph data management and graph mining. Undergraduate students who are majoring in computer science, databases, data and knowledge engineering, and data science will also want to read this SpringerBrief.

Coin-Operated Americans: Rebooting Boyhood at the Video Game Arcade
by Carly A. KocurekVideo gaming: it's a boy's world, right? That's what the industry wants us to think. Why and how we came to comply are what Carly A. Kocurek investigates in this provocative consideration of how an industry's craving for respectability hooked up with cultural narratives about technology, masculinity, and youth at the video arcade.From the dawn of the golden age of video games with the launch of Atari's Pong in 1972, through the industry-wide crash of 1983, to the recent nostalgia-bathed revival of the arcade, Coin-Operated Americans explores the development and implications of the "video gamer" as a cultural identity. This cultural-historical journey takes us to the Twin Galaxies arcade in Ottumwa, Iowa, for a close look at the origins of competitive gaming. It immerses us in video gaming's first moral panic, generated by Exidy's Death Race (1976), an unlicensed adaptation of the film Death Race 2000. And it ventures into the realm of video game films such as Tron and WarGames, in which gamers become brilliant, boyish heroes.Whether conducting a phenomenological tour of a classic arcade or evaluating attempts, then and now, to regulate or eradicate arcades and coin-op video games, Kocurek does more than document the rise and fall of a now-booming industry. Drawing on newspapers, interviews, oral history, films, and television, she examines the factors and incidents that contributed to the widespread view of video gaming as an enclave for young men and boys.A case study of this once emergent and now revived medium became the presumed enclave of boys and young men, Coin-Operated Americans is history that holds valuable lessons for contemporary culture as we struggle to address pervasive sexism in the domain of video games--and in the digital working world beyond.
Cold Cases: Evaluation Models with Follow-up Strategies for Investigators, Second Edition (Advances in Police Theory and Practice)
by James M. Adcock Sarah L. SteinBecause the investigation of cold cases is usually an arduous and time-consuming task, most law enforcement agencies in the United States are not able to dedicate the resources necessary to support the cold case investigation process. However, when those cases are fully pursued and prosecuted, they often result in convictions and lengthy prison terms. Cold Cases: Evaluation Models with Follow-up Strategies for Investigators, Second Edition saves law enforcement time by providing detailed guidelines for determining if a cold case is solvable, and if so, how to organize, manage, and evaluate the investigation. It also provides techniques for developing investigative strategies to complement the evaluation process and resolve the crime.This second edition features a new revised model and methodology for investigating cold cases suitable for all police and public safety agencies—large or small, domestic or international. This new model is more expeditious and convenient for departments that have less manpower and experience in dealing with cold cases. It emphasizes the prioritization of cold cases based on the availability of physical evidence and the chances of deriving matches from said evidence and an identified person of interest.Additional topics covered in the second edition include: How cases go cold Strategies for creating a cold case unit Cold case investigations in a Dutch educational environment—a chapter written by members of the Dutch Police Academy New forensic science technologies, including DNA, CODIS, and AFIS Case studies demonstrating advances in suspectology Strategies for effective investigative interviewing Challenges posed by staged crime scenes in cold cases How to craft a cold case evaluation report The expert authors of this book maintain The Center for the Resolution of Unresolved Crimes and conduct training and consulting worldwide. Their practical book is designed to help law enforcement agencies resurrect long-forgotten cases, bringing closure to victims and holding accountable those who are responsible. This book is part of the Advances in Police Theory and Practice series
The Cold Start Problem: How to Start and Scale Network Effects
by Andrew ChenA startup executive and investor draws on expertise developed at the premier venture capital firm Andreessen Horowitz and as an executive at Uber to address how tech’s most successful products have solved the dreaded "cold start problem”—by leveraging network effects to launch and scale toward billions of users.Although software has become easier to build, launching and scaling new products and services remains difficult. Startups face daunting challenges entering the technology ecosystem, including stiff competition, copycats, and ineffective marketing channels. Teams launching new products must consider the advantages of “the network effect,” where a product or service’s value increases as more users engage with it. Apple, Google, Microsoft, and other tech giants utilize network effects, and most tech products incorporate them, whether they’re messaging apps, workplace collaboration tools, or marketplaces. Network effects provide a path for fledgling products to break through, attracting new users through viral growth and word of mouth.Yet most entrepreneurs lack the vocabulary and context to describe them—much less understand the fundamental principles that drive the effect. What exactly are network effects? How do teams create and build them into their products? How do products compete in a market where every player has them? Andrew Chen draws on his experience and on interviews with the CEOs and founding teams of LinkedIn, Twitch, Zoom, Dropbox, Tinder, Uber, Airbnb, and Pinterest to offer unique insights in answering these questions. Chen also provides practical frameworks and principles that can be applied across products and industries. The Cold Start Problem reveals what makes winning networks thrive, why some startups fail to successfully scale, and, most crucially, why products that create and compete using the network effect are vitally important today.

Collaboration and Technology: 23rd International Conference, CRIWG 2017, Saskatoon, SK, Canada, August 9-11, 2017, Proceedings (Lecture Notes in Computer Science #10391)
by Julita Vassileva Sergio F. Ochoa Tomoo Inoue Carl GutwinIt was approximately two decades ago that the support of communication and collaboration became an important research issue. The technical stimulation for this was the spread of personal computers and computer networks, whilst the social driver was the demand for the support of everyday work, frequently including group work and teamwork. This field of research has become known as Computer-Supported Cooperative Work whilst the systems to support group work are called groupware. Over the two decades, research has been extensively conducted. Various Web-based systems have been researched, some of which are aimed at the support of communication and collaboration. Mobile phones have spread rapidly and communication and collaboration support systems have also been researched on this platform. There are many other technologies such as virtual reality, robotics, multimedia, and ubiquitous computing, each of which provides opportunities for the research field. As the research field is not dependent on the type of technology, but is dependent on the needs of human activity and human beings are social animals, the technical demands of supporting social activities do not diminish. Technologies that potentially are useful for this purpose are being investigated whilst new technologies are invented. As a result of the development of IT, the research and development of communication and collaboration systems is increasingly active. The scope of this publication extends from perspectives, design principles, guidelines, and social aspects of communication and collaboration support systems to the various application systems and the platform technologies.

Collaboration in the Digital Age: How Technology Enables Individuals, Teams and Businesses (Progress in IS)
by Kai Riemer Stefan Schellhammer Michaela MeinertThis book examines how digital technologies enable collaboration as a way for individuals, teams and businesses to connect, create value, and harness new opportunities. Digital technologies have brought the world closer together but also created new barriers and divides. While it is now possible to connect almost instantly and seamlessly across the globe, collaboration comes at a cost; it requires new skills and hidden ‘collaboration work’, and the need to renegotiate the fair distribution of value in multi-stakeholder network arrangements. Presenting state-of-the-art research, case studies, and leading voices in the field, the book provides academics and professionals with insights into the diverse powers of collaboration in the digital age, spanning collaboration among professionals, organisations, and consumers. It brings together contributions from scholars interested in the collaboration of teams, cooperatives, projects, and new cooperative systems, covering a range of sectors from the sharing economy, health care, large project businesses to public sector collaboration.

Collaboration Potential in Virtual Reality: Transforming the Workplace of Tomorrow (SpringerBriefs in Business)
by Marko OrelThe recent shift in labour markets has heightened the demand for alternative work arrangements. Virtual reality (VR) technology plays a significant role in this transition, with remote work as efficient as work performed from an organization's own office space. This book explores the impact of immersive VR technology on the new virtual workspace. Specifically, it examines how VR can enable employees to overcome the distractions associated with working from home, increase their visibility on team projects, build stronger relationships with co-workers, reduce feelings of isolation due to social distancing, and facilitate their engagement in collaborative work processes. It also explores the limitations of two-dimensional, computer-mediated communication tools for flexible working arrangements. It, thus, offers theoretical foundations for future research on office digitalization and subsequent applications of VR technology on office work. It also features the analysis of two dozen problem-centered expert interviews with creators and executives of leading productivity VR tools that enable the remote collaboration between knowledge workers.
