Whether you're tasked with delivering a specific analytics project or simply suspect that you could be deriving more value from your data, this book will inspire you with the opportunities-and inform you of the risks-that exist in data of all shapes and sizes. What You Will Learn * Perform hypothesis testing and understand feature selection and statistical significance to interpret your results with confidence * Implement the core machine learning techniques of regression, classification, clustering and recommendation * Understand the importance of the value of simple statistics and distributions in exploratory data analysis * Scale algorithms to web-sized datasets efficiently using distributed programming models on Hadoop and Spark * Apply suitable analytic approaches for text, graph, and time series data * Interpret the terminology that you will encounter in technical papers * Import libraries from other JVM languages such as Java and Scala * Communicate your findings clearly and convincingly to nontechnical colleagues In Detail The term "data science" has been widely used to define this new profession that is expected to interpret vast datasets and translate them to improved decision-making and performance. Clojure is a powerful language that combines the interactivity of a scripting language with the speed of a compiled language. Together with its rich ecosystem of native libraries and an extremely simple and consistent functional approach to data manipulation, which maps closely to mathematical formula, it is an ideal, practical, and flexible language to meet a data scientist's diverse needs. Taking you on a journey from simple summary statistics to sophisticated machine learning algorithms, this book shows how the Clojure programming language can be used to derive insights from data. Data scientists often forge a novel path, and you'll see how to make use of Clojure's Java interoperability capabilities to access libraries such as Mahout and Mllib for which Clojure wrappers don't yet exist. Even seasoned Clojure developers will develop a deeper appreciation for their language's flexibility! You'll learn how to apply statistical thinking to your own data and use Clojure to explore, analyze, and visualize it in a technically and statistically robust way. You can also use Incanter for local data processing and ClojureScript to present interactive visualisations and understand how distributed platforms such as Hadoop sand Spark's MapReduce and GraphX's BSP solve the challenges of data analysis at scale, and how to explain algorithms using those programming models. Above all, by following the explanations in this book, you'll learn not just how to be effective using the current state-of-the-art methods in data science, but why such methods work so that you can continue to be productive as the field evolves into the future. Style and approach This is a practical guide to data science that teaches theory by example through the libraries and frameworks accessible from the Clojure programming language.

Clone: The Road To Dolly, And The Path Ahead
by Gina KolataThe birth of Dolly -- the world's first clone -- placed in our hands the secret of creation. Few discoveries have so altered our notion of what it means to be human, or presented such a Gordian knot of ethical, spiritual, and scientific questions. Noted science journalist Gina Kolata broke the news nationally in The New York Times and was the first reporter to speak with Dr. Ian Wilmut, the embryologist who cloned Dolly. Now Kolata reveals the story behind Dolly, interweaving the social and cultural tales of our fear and fascination with cloning, reaching back nearly a century, with the riveting scientific accountof how a clone came to be and the mind-boggling questions Dolly presents for our future.Clone is a compelling blend of scientific suspense, dreams dashed, and frauds exposed, with provocative philosophical questions and an astute assessment of why Dolly's birth was only possible now. Like The Making of the Atomic Bomb, Lucy, and Chaos, this book gives us a window on history in the making, and an understanding of its profound effect on our lives.

Closer: Performance, Technologies, Phenomenology
by Susan KozelIn Closer, Susan Kozel draws on live performance practice, digital technologies, and the philosophical approach of phenomenology. Trained in dance and philosophy, Kozel places the human body at the center of explorations of interactive interfaces, responsive systems, and affective computing, asking what can be discovered as we become closer to our computers--as they become extensions of our ways of thinking, moving, and touching. Performance, Kozel argues, can act as a catalyst for understanding wider social and cultural uses of digital technology. Taking this one step further, performative acts of sharing the body through our digital devices foster a collaborative construction of new physical states, levels of conscious awareness, and even ethics. We re-encounter ourselves and others through our interactive computer systems. What we need now are conceptual and methodological frameworks to reflect this. Kozel offers a timely reworking of the phenomenology of French philosopher Maurice Merleau-Ponty. This method, based on a respect for lived experience, begins by listening to the senses and noting insights that arrive in the midst of dance, or quite simply in the midst of life. The combination of performance and phenomenology offered by Closer yields entwinements between experience and reflection that shed light on, problematize, or restructure scholarly approaches to human bodies using digital technologies. After outlining her approach and methodology and clarifying the key concepts of performance, technologies, and virtuality, Kozel applies phenomenological method to the experience of designing and performing in a range of computational systems: telematics, motion capture, responsive architectures, and wearable computing. The transformative potential of the alchemy between bodies and technologies is the foundation of Closer. With careful design, future generations of responsive systems and mobile devices can expand our social, physical, and emotional exchanges.

The Closing of the Auditor’s Mind?: How to Reverse the Erosion of Trust, Virtue, and Wisdom in Modern Auditing (Security, Audit and Leadership Series)
by David J. O'ReganIn The Closing of the Auditor’s Mind?, author David J. O’Regan describes internal auditing as an important "binding agent" of social cohesion, for the accountability of individuals and organizations and also at aggregated levels of social trust. However, O’Regan also reveals that internal auditing faces two severe challenges – an external challenge of adaptation and an internal challenge of fundamental reform.The adaptation challenge arises from ongoing, paradigmatic shifts in accountability and social trust. The command- and- control, vertical hierarchies of traditional bureaucracies are being replaced in importance by networked, flattened patterns of accountability. The most challenging assurance demands of the modern era are increasingly located in three institutional domains – in the inner workings of organizations; in intermediary spaces at organizational boundaries; and in extra-mural locations. Internal auditing continues to cling, barnacle- like, to the inner workings of traditional, bureaucratic structures, and it has little to offer the emerging assurance demands on or beyond institutional boundaries. The reform challenge arises from internal auditing’s prevailing tendency toward a rigid, algorithmic, checklist mindset that suppresses practitioners’ creativity and critical thinking. This trend is increasingly narrowing internal auditing’s intellectual and moral horizons. Under the pressures of these challenges, internal auditing is struggling to fulfil its primary purpose of serving the public interest.O’Regan’s powerful book focuses on: The redistribution of social trust from traditional, hierarchical institutions to diffuse, horizontally distributed networks The perennial validity of the classical virtues as the humane foundation of professional activity The role of creative expertise in promoting professional wisdom The Closing of the Auditor’s Mind? is a philosophical audit of a profession on the threshold of crisis. The book presupposes no prior knowledge of philosophy, nor indeed of auditing. Philosophical technicalities are contained in an Appendix, leaving the main text jargon-free. O’Regan provides original and striking perspectives on the malaise of modern internal auditing, and he proposes radical remedies. This captivating and well-informed book is a must-read for all who are concerned with our collective socio-economic and political well-being.
