Scaling Up Machine Learning
by John Langford Ron Bekkerman Mikhail BilenkoThis book presents an integrated collection of representative approaches for scaling up machine learning and data mining methods on parallel and distributed computing platforms. Demand for parallelizing learning algorithms is highly task-specific: in some settings it is driven by the enormous dataset sizes, in others by model complexity or by real-time performance requirements. Making task-appropriate algorithm and platform choices for large-scale machine learning requires understanding the benefits, trade-offs, and constraints of the available options. Solutions presented in the book cover a range of parallelization platforms from FPGAs and GPUs to multi-core systems and commodity clusters, concurrent programming frameworks including CUDA, MPI, MapReduce, and DryadLINQ, and learning settings (supervised, unsupervised, semi-supervised, and online learning). Extensive coverage of parallelization of boosted trees, SVMs, spectral clustering, belief propagation and other popular learning algorithms and deep dives into several applications make the book equally useful for researchers, students, and practitioners.

Scaling Up: How Data Curation Can Help Address Key Issues in Qualitative Data Reuse and Big Social Research (Synthesis Lectures on Information Concepts, Retrieval, and Services)
by Sara MannheimerThis book explores the connections between qualitative data reuse, big social research, and data curation. A review of existing literature identifies the key issues of context, data quality and trustworthiness, data comparability, informed consent, privacy and confidentiality, and intellectual property and data ownership. Through interviews of qualitative researchers, big social researchers, and data curators, the author further examines each key issue and produces new insights about how domain differences affect each community of practice’s viewpoints, different strategies that researchers and curators use to ensure responsible practice, and different perspectives on data curation. The book suggests that encouraging connections between qualitative researchers, big social researchers, and data curators can support responsible scaling up of social research, thus enhancing discoveries in social and behavioral science.

Scandal and Democracy: Media Politics in Indonesia
by Mary E. McCoySuccessful transitions to enduring democracy are both difficult and rare. In Scandal and Democracy, Mary E. McCoy explores how newly democratizing nations can avoid reverting to authoritarian solutions in response to the daunting problems brought about by sudden change. The troubled transitions that have derailed democratization in nations worldwide make this problem a major concern for scholars and citizens alike.This study of Indonesia's transition from authoritarian rule sheds light on the fragility not just of democratic transitions but of democracy itself and finds that democratization's durability depends, to a surprising extent, on the role of the media, particularly its airing of political scandal and intraelite conflict. More broadly, Scandal and Democracy examines how the media's use of new freedoms can help ward off a slide into pseudodemocracy or a return to authoritarian rule. As Indonesia marks the twentieth anniversary of its democratic revolution of 1998, it remains among the world's most resilient new democracies and one of the few successful democratic transitions in the Muslim world. McCoy explains the media's central role in this change and corroborates that finding with comparative cases from Mexico, Tunisia, and South Korea, offering counterintuitive insights that help make sense of the success and failure of recent transitions to democracy.
Scandalous Leadership: Prime Ministers' and Presidents' Scandals and the Press
by M. J. TrowAn exploration of the moral blemishes that have dogged the leaders of Great Britain and the United States. Before Britain had a prime minister – and before they invented America – the dictator Oliver Cromwell urged the artist Lely to paint him ‘warts and all’. This book deals with some of the ‘all’, but is mostly about the warts, the moral blemishes that have dogged the leaders of two of the greatest countries on earth for 300 years. Scandalously, there are still no qualifications necessary for the job of prime minister or president, two of the most important positions in the world. And that lack of ability shows itself in spades throughout these pages. Robert Walpole knew that ‘every man has his price’ and bought people accordingly. Viscount Goderich broke down in tears, begging the king to fire him. George Washington, the revered saint of American creation, blew with the wind and owned slaves. Abraham Lincoln was prepared to send African Americans back to Africa to save the Union. William Gladstone popped out from Downing street to ‘save’ prostitutes. David Lloyd George gave people titles for money. Warren Harding had a string of mistresses, as did John Kennedy. And all this happened before Donald Trump! Thank God the fourth estate was there, the free press watching every move of politicians. Who was watching them, of course, is another story. If you thought – and prayed – that the occupants of No. 10 and the White House were honorable, competent people, you’re in for a bit of a shock.
Scanning Negatives and Slides: Digitizing Your Photographic Archive, 2nd Edition
by Sascha Steinhoff<p>Many photographers have either moved into digital photography exclusively or use both analog and digital media in their work. In either case, there is sure to be an archive of slides and negatives that cannot be directly integrated into the new digital workflow, nor can it be archived in a digital format. Increasingly, photographers are trying to bridge this gap with the use of high-performance film scanners. <br/><br/>\nIn this 2nd edition, you will learn how to achieve the best possible digital image from a negative or a slide, and how to build a workflow to make this process efficient, repeatable, and reliable. The author uses Nikon's film scanners, but all steps can easily be accomplished while using a different scanner. The most common software tools for scanning (SilverFast, VueScan, NikonScan) are not only covered extensively in the book, but trial versions are also provided on a DVD, which also contains other useful tools for image editing, as well as numerous sample scans.</p>

Scheduling and Congestion Control for Wireless Internet
by Xin WangThis brief proposes that the keys to internet cross-layer optimization are the development of non-standard implicit primal-dual solvers for underlying optimization problems, and design of jointly optimal network protocols as decomposition of such solvers. Relying on this novel design-space oriented approach, the author develops joint TCP congestion control and wireless-link scheduling schemes for wireless applications over Internet with centralized and distributed (multi-hop) wireless links. Different from the existing solutions, the proposed schemes can be asynchronously implemented without message passing among network nodes; thus they are readily deployed with current infrastructure. Moreover, global convergence/stability of the proposed schemes to optimal equilibrium is established using the Lyapunov method in the network fluid model. Simulation results are provided to evaluate the proposed schemes in practical networks.
Scheduling and Reconfiguration of Real-Time Systems: A Supervisory Control Approach
by Xi Wang ZhiWu LiThis book presents a methodology for the real-time scheduling problems of real-time systems (RTS) from the viewpoint of control theory. Generally, any system can be viewed as an RTS if it performs real-time application functions and behaves correctly depending on given logical activities and satisfying specified deadlines for the activities. This monograph provides broad views and detailed introductions to supervisory control theory (SCT) and its application in real-time scheduling and reconfiguration. Based on three popular SCT modelling frameworks, discrete-event system (DES), timed DES (TDES), and state-tree structures (STS), the authors provide RTS modelling frameworks; thereafter, SCT is used to find their safe execution sequences. As the main contribution, we use (untimed) DES events to represent the execution and preemption of each individual RTS task. This modelling formalism brings the possibilities to model the preemptions of tasks’ executions. Furthermore, in some cases, priorities cannot be assigned to real-time tasks. In order to solve this problem, a matrix-based priority-free conditional-preemption (PFCP) relation is provided, which generalizes fixed-priority (FP) RTS scheduling. As a natural extension, a generalized modular modelling framework is presented to model the task parameters instead of the global real-time task. The modular models are taken to be generic entities, which also considers the exact execution time of real-time tasks. STS are undoubtedly recognized as a computationally efficient SCT framework which manages the state explosion problem significantly. Hence, building on the (untimed) modular RTS models, a novel STS-based RTS modeling framework is formulated, by assigning dynamic priorities as specified optimality criteria, which can be utilized to model sporadic RTS processing both sporadic and (multi-period) periodic tasks, providing a small set of the safe execution sequences which rank at the top.
