Book excerpt: "One of the more momentous books of the decade." —The New York Times Book Review Nate Silver built an innovative system for predicting baseball performance, predicted the 2008 election within a hair’s breadth, and became a national sensation as a blogger—all by the time he was thirty. He solidified his standing as the nation's foremost political forecaster with his near perfect prediction of the 2012 election. Silver is the founder and editor in chief of the website FiveThirtyEight. Drawing on his own groundbreaking work, Silver examines the world of prediction, investigating how we can distinguish a true signal from a universe of noisy data. Most predictions fail, often at great cost to society, because most of us have a poor understanding of probability and uncertainty. Both experts and laypeople mistake more confident predictions for more accurate ones. But overconfidence is often the reason for failure. If our appreciation of uncertainty improves, our predictions can get better too. This is the “prediction paradox”: The more humility we have about our ability to make predictions, the more successful we can be in planning for the future. In keeping with his own aim to seek truth from data, Silver visits the most successful forecasters in a range of areas, from hurricanes to baseball to global pandemics, from the poker table to the stock market, from Capitol Hill to the NBA. He explains and evaluates how these forecasters think and what bonds they share. What lies behind their success? Are they good—or just lucky? What patterns have they unraveled? And are their forecasts really right? He explores unanticipated commonalities and exposes unexpected juxtapositions. And sometimes, it is not so much how good a prediction is in an absolute sense that matters but how good it is relative to the competition. In other cases, prediction is still a very rudimentary—and dangerous—science. Silver observes that the most accurate forecasters tend to have a superior command of probability, and they tend to be both humble and hardworking. They distinguish the predictable from the unpredictable, and they notice a thousand little details that lead them closer to the truth. Because of their appreciation of probability, they can distinguish the signal from the noise. With everything from the health of the global economy to our ability to fight terrorism dependent on the quality of our predictions, Nate Silver’s insights are an essential read.

Book Synopsis Random Signals and Noise by : Shlomo Engelberg
Download or read book Random Signals and Noise written by Shlomo Engelberg and published by CRC Press. This book was released on 2018-10-03 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the nature of random signals and noise is critically important for detecting signals and for reducing and minimizing the effects of noise in applications such as communications and control systems. Outlining a variety of techniques and explaining when and how to use them, Random Signals and Noise: A Mathematical Introduction focuses on applications and practical problem solving rather than probability theory. A Firm Foundation Before launching into the particulars of random signals and noise, the author outlines the elements of probability that are used throughout the book and includes an appendix on the relevant aspects of linear algebra. He offers a careful treatment of Lagrange multipliers and the Fourier transform, as well as the basics of stochastic processes, estimation, matched filtering, the Wiener-Khinchin theorem and its applications, the Schottky and Nyquist formulas, and physical sources of noise. Practical Tools for Modern Problems Along with these traditional topics, the book includes a chapter devoted to spread spectrum techniques. It also demonstrates the use of MATLAB® for solving complicated problems in a short amount of time while still building a sound knowledge of the underlying principles. A self-contained primer for solving real problems, Random Signals and Noise presents a complete set of tools and offers guidance on their effective application.

Book Synopsis Signal Processing Noise by : Vyacheslav Tuzlukov
Download or read book Signal Processing Noise written by Vyacheslav Tuzlukov and published by CRC Press. This book was released on 2018-10-08 with total page 688 pages. Available in PDF, EPUB and Kindle. Book excerpt: Additive and multiplicative noise in the information signal can significantly limit the potential of complex signal processing systems, especially when those systems use signals with complex phase structure. During the last few years this problem has been the focus of much research, and its solution could lead to profound improvements in applications of complex signals and coherent signal processing. Signal Processing Noise sets forth a generalized approach to signal processing in multiplicative and additive noise that represents a remarkable advance in signal processing and detection theory. This approach extends the boundaries of the noise immunity set by classical and modern signal processing theories, and systems constructed on this basis achieve better detection performance than that of systems currently in use. Featuring the results of the author's own research, the book is filled with examples and applications, and each chapter contains an analysis of recent observations obtained by computer modelling and experiments. Tables and illustrations clearly show the superiority of the generalized approach over both classical and modern approaches to signal processing noise. Addressing a fundamental problem in complex signal processing systems, this book offers not only theoretical development, but practical recommendations for raising noise immunity in a wide range of applications.
Download or read book Signal & Noise written by John Griesemer and published by Picador. This book was released on 2004-04-01 with total page 616 pages. Available in PDF, EPUB and Kindle. Book excerpt: Signal & Noise is the epic page-turning story of the laying of the trans-Atlantic cable, and the men and women who are caught in its monumental tide. It is also a novel about the collision of worlds seen and unseen: the present and the future; the living and the dead; the real and the imagined. On a wet London morning in 1857, American engineer Chester Ludlow arrives on the muddy banks of the Isle of Dogs to witness the launch of the largest steamship ever built, the Great Eastern. Also amidst the tumultuous throng is Jack Trace, a lonely bachelor and sketch artist hoping to make his name as an illustrator and journalist in the hurly burly of Fleet Street. Other witnesses include a drunken German by the name of Marx; the child who will christen the massive vessel by the wrong name; and Isambard Kingdom Brunel, the ship's apoplectic and dwarfish architect who will soon die in ignominy. As chief engineer for the Atlantic Cable Company, the charismatic Chester enters the orbit of business and showmanship embodied by J. Beaumol Spude, the bombastic Western beef magnate who will mastermind the funding of the project; Joachim Lindt, creator of the Phantasmagorium, an animated tableaux vivant; and his beautiful wife, the musician Katerina Lindt. Drawn by the demands and adventure of creating the first transoceanic telegraph, Chester leaves behind his fragile wife, Franny, at the family estate of Willing Mind in Maine. Abandoned and still mourning the accidental death of their four-year-old daughter, Franny finds solace in the company of Chester's troubled brother, Otis, who introduces her to the mysteries of the world of spiritualism just as séancing is becoming all the rage in the jittery times leading up to the Civil War. As Chester achieves renown as the glamorous engineer of the trans-Atlantic project, Franny, desperate to contact her dead child, becomes the preeminent spirit conjuror of a war-torn America.

What You Should Know About Politics . . . But Don’t breaks it all down, issue by issue, explaining who stands for what, and why, whether it’s the economy, the war in Iraq, health care, oil and renewable energy sources, or climate change. If you’re a Democrat, a Republican, or somewhere in between, it’s the perfect book to brush up on a single topic or read through to get a deeper understanding of the often mucky world of American politics.
Book Synopsis Phase Noise in Signal Sources by : W. P. Robins
Download or read book Phase Noise in Signal Sources written by W. P. Robins and published by IET. This book was released on 1984 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains a thorough treatment of phase noise, its relationship to thermal noise and associated subjects such as frequency stability. The design of low phase noise signal sources, including oscillators and synthesisers, is explained and in many cases the measured phase noise characteristics are compared with the theoretical predictions. Full theoretical treatments are combined with physical explanations, helpful comments, examples of manufactured equipment and practical tips. Overall system performance degradations due to unwanted phase noise are fully analysed for radar systems and for both analogue and digital communications systems. Specifications for the acceptable phase noise performance of signal sources to be used in such systems are derived after allowing for both technical and economic optimisation. The mature engineer whose mathematics may be somewhat rusty will find that every effort has been made to use the lowest level of mathematical sophistication that is compatible with a full analysis and every line of each mathematical argument has been set out so that the book may be read and understood even in an armchair. Due to a novel approach to the analytical treatment of narrow band noise, the book is simple to understand while simultaneously carrying the analysis further in several areas than any existing publication.

Download or read book Signal written by Stephen Few and published by . This book was released on 2015-05-01 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: Teaches the analytical skills necessary to glean value from the warehouses of accumulating data In this age of so-called Big Data, organizations are scrambling to implement new software and hardware to increase the amount of data they collect and store. However, in doing so they are unwittingly making it harder to find the needles of useful information in the rapidly growing mounds of hay. If you don't know how to differentiate signals from noise, adding more noise only makes things worse. When we rely on data for making decisions, how do we tell what qualifies as a signal and what is merely noise? In and of itself, data is neither. Assuming that data is accurate, it is merely a collection of facts. When a fact is true and useful, only then is it a signal. When it's not, it's noise. It's that simple. In "Signal," Stephen Few provides the straightforward, practical instruction in everyday signal detection that has been lacking until now. Using data visualization methods, he teaches how to apply statistics to gain a comprehensive understanding of one's data and adapts the techniques of Statistical Process Control in new ways to detect not just changes in the metrics but also changes in the patterns that characterize data.
Book Synopsis Signal Detection in Non-Gaussian Noise by : Saleem A. Kassam
Download or read book Signal Detection in Non-Gaussian Noise written by Saleem A. Kassam and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains a unified treatment of a class of problems of signal detection theory. This is the detection of signals in addi tive noise which is not required to have Gaussian probability den sity functions in its statistical description. For the most part the material developed here can be classified as belonging to the gen eral body of results of parametric theory. Thus the probability density functions of the observations are assumed to be known, at least to within a finite number of unknown parameters in a known functional form. Of course the focus is on noise which is not Gaussian; results for Gaussian noise in the problems treated here become special cases. The contents also form a bridge between the classical results of signal detection in Gaussian noise and those of nonparametric and robust signal detection, which are not con sidered in this book. Three canonical problems of signal detection in additive noise are covered here. These allow between them formulation of a range of specific detection problems arising in applications such as radar and sonar, binary signaling, and pattern recognition and classification. The simplest to state and perhaps the most widely studied of all is the problem of detecting a completely known deterministic signal in noise. Also considered here is the detection random non-deterministic signal in noise. Both of these situa of a tions may arise for observation processes of the low-pass type and also for processes of the band-pass type.
