A description of perturbation-based methods developed in machine learning to augment novel optimization methods with strong statistical guarantees.In nearly all machine learning, decisions must be made given current knowledge. Surprisingly, making what is believed to be the best decision is not always the best strategy, even when learning in a supervised learning setting. An emerging body of work on learning under different rules applies perturbations to decision and learning procedures. These methods provide simple and highly efficient learning rules with improved theoretical guarantees. This book describes perturbation-based methods developed in machine learning to augment novel optimization methods with strong statistical guarantees, offering readers a state-of-the-art overview.Chapters address recent modeling ideas that have arisen within the perturbations framework, including Perturb & MAP, herding, and the use of neural networks to map generic noise to distribution over highly structured data. They describe new learning procedures for perturbation models, including an improved EM algorithm and a learning algorithm that aims to match moments of model samples to moments of data. They discuss understanding the relation of perturbation models to their traditional counterparts, with one chapter showing that the perturbations viewpoint can lead to new algorithms in the traditional setting. And they consider perturbation-based regularization in neural networks, offering a more complete understanding of dropout and studying perturbations in the context of deep neural networks.

The lives of people (mostly women) who help to produce science or who are affected by it.The stories in Schrödinger's Wife (and Other Possibilities) travel through laboratories, observatories, rockets, hotel rooms, hospitals, out to the Antarctic and into outer space, following the trails of women scientists, technicians, patients, doctors, and spouses in their encounters with some of the most extraordinary aspects of modern science.In these science-inspired tales the nuclear physicist Lise Meitner discovers the secrets of nuclear fission while fleeing from the Nazis. An employee in the underground laboratory CERN refuses to have her own photo taken. The biologist Margaret Bastock must figure our the impact of genes on behavior while coping with post-war expectations of women’s own behavior. Scientists from East and West Germany stationed at opposite sides of Antarctica experience their own fall of the Berlin Wall. The elusive physicist Bruno Pontecorvo theorizes about an equally elusive particle. Schrödinger’s wife Anny uses his theory to get her revenge on her philandering husband. A scientific theory worries about being discovered by a woman, and a resident in a special institution extrapolates the history of the universe from a piece of toast. In this, her second collection of short stories, Pippa Goldschmidt explores the lives of real and imaginary scientists, focusing on the human emotions and social connections behind the discoveries.

An antiracist theory of cleaning.In Making the World Clean: Wasted Lives, Wasted Environment, and Racial Capitalism, Françoise Vergès examines the racial and gendered politics of wasting lands, bodies, and resources and the organized deprivation of clean water, shelter, and access to health services—in other words, the structural denial, along racial lines, of vital needs. Through 38 short sections, she looks at the social relations that have made cleaning into drudgery and into a racialized, gendered, poorly paid job that is nevertheless necessary for any society to function. She concludes with the proposition of a feminist, decolonial, antiracist, anti-patriarchal, and anti-capitalist politics of cleaning. Or, simply put, of “decolonial cleaning.”To Vergès, the structural denial of the elemental needs of women of color (sanitary pads, access to water, and privacy for basic washing), and why these needs are considered insignificant and trivial, shows how racism and class war are gendered. By examining the banal, the trivial, and the elemental, the author addresses cleaning as a necessity rather than the maintenance of a consumerist lifestyle, a condition of basic care of the body and the mind that is considered with indifference by racial capitalism, white environmentalism, and even, too often, by humanitarian organizations. She argues that by building “life-affirming institutions,” as Ruth Wilson Gilmore advocates, struggles against the whitening of cleaning create sites of freedom. “Decolonial cleaning” imagines cleaning as taking care of land, humans, plants, animals, and rivers, not seeking to discipline them or transform them into commodities or objects of conservation but cleaning as a practice dedicated to sustaining the living world.

"Trapped in a London laboratory during a worker uprising in 1924, ex-artillery officer and physics instructor Jeremy Tuft awakens 150 years later - on the eve of a new Dark Age! England has become a neo-medieval society whose inhabitants have forgotten how to build or operate machinery. Though he is at first disconcerted by the failure of his own era's smug doctrine of Progress, Tuft eventually decides that post-civilized life is simpler, more peaceful. That is, until northern English and Welsh tribes invade- at which point Tuft sets about reinventing weapons of mass destruction"--

"The definitive history of the invention of D&D"--

"This is a book about cities - how unexpectedly different they were in various countries and times, and cities that never existed, but someone dreamed of them or feared them. The project uses examples from a wide spectrum of different cultures, it researches the existential and universal question of what means to be human - as a child and as an adult - in order to explore the diversity of how people live globally and throughout history"--

An argument that conceiving of economic value as a social force makes it possible to develop a new and more powerful theory of market behavior.With the advent of the 2007–2008 financial crisis, the economics profession itself entered into a crisis of legitimacy from which it has yet to emerge. Despite the obviousness of their failures, however, economists continue to rely on the same methods and to proceed from the same underlying assumptions. André Orléan challenges the neoclassical paradigm in this book, with a new way of thinking about perhaps its most fundamental concept, economic value.Orléan argues that value is not bound up with labor, or utility, or any other property that preexists market exchange. Economic value, he contends, is a social force whose vast sphere of influence, amounting to a kind of empire, extends to every aspect of economic life. Markets are based on the identification of value with money, and exchange value can only be regarded as a social institution. Financial markets, for example, instead of defining an extrinsic, objective value for securities, act as a mechanism for arriving at a reference price that will be accepted by all investors. What economists must therefore study,Orléan urges, is the hold that value has over individuals and how it shapes their perceptions and behavior.Awarded the prestigious Prix Paul Ricoeur on its original publication in France in 2011, The Empire of Value has been substantially revised and enlarged for this edition, with an entirely new section discussing the financial crisis of 2007–2008.

How sonically distinctive digital “signatures”—including reverb, glitches, and autotuning—affect the aesthetics of popular music, analyzed in works by Prince, Lady Gaga, and others.Is digital production killing the soul of music? Is Auto-Tune the nadir of creative expression? Digital technology has changed not only how music is produced, distributed, and consumed but also—equally important but not often considered—how music sounds. In this book, Ragnhild Brøvig and Anne Danielsen examine the impact of digitization on the aesthetics of popular music. They investigate sonically distinctive “digital signatures”—musical moments when the use of digital technology is revealed to the listener. The particular signatures of digital mediation they examine include digital reverb and delay, MIDI and sampling, digital silence, the virtual cut-and-paste tool, digital glitches, microrhythmic manipulation, and autotuning—all of which they analyze in specific works by popular artists.Combining technical and historical knowledge of music production with musical analyses, aesthetic interpretations, and theoretical discussions, Brøvig and Danielsen offer unique insights into how digitization has changed the sound of popular music and the listener's experience of it. For example, they show how digital reverb and delay have allowed experimentation with spatiality by analyzing Kate Bush's “Get Out of My House”; they examine the contrast between digital silence and the low-tech noises of tape hiss or vinyl crackle in Portishead's “Stranger”; and they describe the development of Auto-Tune—at first a tool for pitch correction—into an artistic effect, citing work by various hip-hop artists, Bon Iver, and Lady Gaga.

Experts discuss the challenges faced in agrobiodiversity and conservation, integrating disciplines that range from plant and biological sciences to economics and political science.Wide-ranging environmental phenomena—including climate change, extreme weather events, and soil and water availability—combine with such socioeconomic factors as food policies, dietary preferences, and market forces to affect agriculture and food production systems on local, national, and global scales. The increasing simplification of food systems, the continuing decline of plant species, and the ongoing spread of pests and disease threaten biodiversity in agriculture as well as the sustainability of food resources. Complicating the situation further, the multiple systems involved—cultural, economic, environmental, institutional, and technological—are driven by human decision making, which is inevitably informed by diverse knowledge systems. The interactions and linkages that emerge necessitate an integrated assessment if we are to make progress toward sustainable agriculture and food systems.This volume in the Strüngmann Forum Reports series offers insights into the challenges faced in agrobiodiversity and sustainability and proposes an integrative framework to guide future research, scholarship, policy, and practice. The contributors offer perspectives from a range of disciplines, including plant and biological sciences, food systems and nutrition, ecology, economics, plant and animal breeding, anthropology, political science, geography, law, and sociology. Topics covered include evolutionary ecology, food and human health, the governance of agrobiodiversity, and the interactions between agrobiodiversity and climate and demographic change.

Examinations of wargaming for entertainment, education, and military planning, in terms of design, critical analysis, and historical contexts. Games with military themes date back to antiquity, and yet they are curiously neglected in much of the academic and trade literature on games and game history. This volume fills that gap, providing a diverse set of perspectives on wargaming's past, present, and future. In Zones of Control, contributors consider wargames played for entertainment, education, and military planning, in terms of design, critical analysis, and historical contexts. They consider both digital and especially tabletop games, most of which cover specific historical conflicts or are grounded in recognizable real-world geopolitics. Game designers and players will find the historical and critical contexts often missing from design and hobby literature; military analysts will find connections to game design and the humanities; and academics will find documentation and critique of a sophisticated body of cultural work in which the complexity of military conflict is represented in ludic systems and procedures. Each section begins with a long anchoring chapter by an established authority, which is followed by a variety of shorter pieces both analytic and anecdotal. Topics include the history of playing at war; operations research and systems design; wargaming and military history; wargaming's ethics and politics; gaming irregular and non-kinetic warfare; and wargames as artistic practice.
