Because the computer gathers knowledge from experience, there is no need for a human computer operator to formally specify all the knowledge that the computer needs. The hierarchy of concepts allows the computer to learn complicated concepts by building them out of simpler ones; a graph of these hierarchies would be many layers deep. This book introduces a broad range of topics in deep learning.The text offers mathematical and conceptual background, covering relevant concepts in linear algebra, probability theory and information theory, numerical computation, and machine learning. It describes deep learning techniques used by practitioners in industry, including deep feedforward networks, regularization, optimization algorithms, convolutional networks, sequence modeling, and practical methodology; and it surveys such applications as natural language processing, speech recognition, computer vision, online recommendation systems, bioinformatics, and videogames. Finally, the book offers research perspectives, covering such theoretical topics as linear factor models, autoencoders, representation learning, structured probabilistic models, Monte Carlo methods, the partition function, approximate inference, and deep generative models.Deep Learning can be used by undergraduate or graduate students planning careers in either industry or research, and by software engineers who want to begin using deep learning in their products or platforms. A website offers supplementary material for both readers and instructors.

    Just over fifteen years later, he had transformed himself into the charismatic CEO of a company worth $47 billion--at least on paper. With his long hair and feel-good mantras, the 6-foot-five Neumann, who grew up in part on a kibbutz, looked the part of a messianic Silicon Valley entrepreneur. The vision he offered was mesmerizing: a radical reimagining of work space for a new generation, with its fluid jobs and lax office culture. He called it WeWork. Though the company was merely subleasing amenity-filled office space to freelancers and small startups, Neumann marketed it like a revolutionary product--and investors swooned.As billions of funding dollars poured in, Neumann's ambitions grew limitless. WeWork wasn't just an office space provider, he boasted. It would build schools, create WeWork cities, even colonize Mars. Could he, Neumann wondered from the ice bath he'd installed in his office, become the first trillionaire or a world leader? In pursuit of its founder's grandiose vision, the company spent money faster than it could bring it in. From his private jet, sometimes clouded with marijuana smoke, the CEO scoured the globe for more capital. In late 2019, just weeks before WeWork's highly publicized IPO, a Hail Mary effort to raise cash, everything fell apart. Neumann was ousted from his company--but still was poised to walk away a billionaire.Calling to mind the recent demise of Theranos and the hubris of the dotcom era bust, WeWork's extraordinary rise and staggering implosion were fueled by disparate characters in a financial system blind to its risks, from a Japanese billionaire with designs on becoming the Warren Buffet of tech, to leaders at JPMorgan and Goldman Sachs who seemed intoxicated by a Silicon Valley culture where sensible business models lost out to youthful CEOs who promised disruption. Why did some of the biggest names in banking and venture capital buy the hype? And what does the future hold for Silicon Valley unicorns? Wall Street Journal reporters Eliot Brown and Maureen Farrell explore these questions in this definitive account of WeWork's unraveling.

    How can today's computers perform such a bewildering variety of tasks if computing is just glorified arithmetic? The answer, as Martin Davis lucidly illustrates, lies in the fact that computers are essentially engines of logic. Their hardware and software embody concepts developed over centuries by logicians such as Leibniz, Boole, and Godel, culminating in the amazing insights of Alan Turing. The Universal Computer traces the development of these concepts by exploring with captivating detail the lives and work of the geniuses who first formulated them. Readers will come away with a revelatory understanding of how and why computers work and how the algorithms within them came to be.

    One of the most coveted tools in a spy's arsenal, a zero day has the power to silently spy on your iPhone, dismantle the safety controls at a chemical plant, alter an election, and shut down the electric grid (just ask Ukraine).For decades, under cover of classification levels and non-disclosure agreements, the United States government became the world's dominant hoarder of zero days. U.S. government agents paid top dollar-first thousands, and later millions of dollars- to hackers willing to sell their lock-picking code and their silence. Then the United States lost control of its hoard and the market. Now those zero days are in the hands of hostile nations and mercenaries who do not care if your vote goes missing, your clean water is contaminated, or our nuclear plants melt down.Filled with spies, hackers, arms dealers, and a few unsung heroes, written like a thriller and a reference, This Is How They Tell Me the World Ends is an astonishing feat of journalism. Based on years of reporting and hundreds of interviews, The New York Times reporter Nicole Perlroth lifts the curtain on a market in shadow, revealing the urgent threat faced by us all if we cannot bring the global cyber arms race to heel.

    He left quiet Cambridge, where he had lived for thirty years and made his earth-shattering discoveries, and moved to London to take up the post of Warden of His Majesty’s Mint. Newton was preceded to the city by a genius of another kind, the budding criminal William Chaloner. Thanks to his preternatural skills as a counterfeiter, Chaloner was rapidly rising in London’s highly competitive underworld, at a time when organized law enforcement was all but unknown and money in the modern sense was just coming into being. Then he crossed paths with the formidable new warden. In the courts and streets of London—and amid the tremors of a world being transformed by the ideas Newton himself had set in motion—the two played out an epic game of cat and mouse.

      Statistics are everywhere, as integral to science as they are to business, and in the popular media hundreds of times a day. In this age of big data, a basic grasp of statistical literacy is more important than ever if we want to separate the fact from the fiction, the ostentatious embellishments from the raw evidence -- and even more so if we hope to participate in the future, rather than being simple bystanders. In The Art of Statistics, world-renowned statistician David Spiegelhalter shows readers how to derive knowledge from raw data by focusing on the concepts and connections behind the math. Drawing on real world examples to introduce complex issues, he shows us how statistics can help us determine the luckiest passenger on the Titanic, whether a notorious serial killer could have been caught earlier, and if screening for ovarian cancer is beneficial. The Art of Statistics not only shows us how mathematicians have used statistical science to solve these problems -- it teaches us how we too can think like statisticians. We learn how to clarify our questions, assumptions, and expectations when approaching a problem, and -- perhaps even more importantly -- we learn how to responsibly interpret the answers we receive. Combining the incomparable insight of an expert with the playful enthusiasm of an aficionado, The Art of Statistics is the definitive guide to stats that every modern person needs.

    In fact, as @WAR shows, U.S. hackers were crucial to our victory in Iraq. Shane Harris delves into the frontlines of America’s new cyber war. As recent revelations have shown, government agencies are joining with tech giants like Google and Facebook to collect vast amounts of information. The military has also formed a new alliance with tech and finance companies to patrol cyberspace, and Harris offers a deeper glimpse into this partnership than we have ever seen before. Finally, Harris explains what the new cybersecurity regime means for all of us, who spend our daily lives bound to the Internet — and are vulnerable to its dangers.

    It’s about how people, organizations and societies can and must hit refresh—transform—in their persistent quest for new energy, new ideas, relevance and renewal. At the core, it’s about us humans and our unique qualities, like empathy, which will become ever more valuable in a world where the torrent of technology will disrupt like never before. As much a humanist as a technologist, Nadella defines his mission and that of the company he leads as empowering every person and every organization on the planet to achieve more.

    Together they changed the course of history.Legendary financier, philanthropist, and society figure Alfred Lee Loomis gathered the most visionary scientific minds of the twentieth century—Albert Einstein, Werner Heisenberg, Niels Bohr, Enrico Fermi, and others—at his state-of-the-art laboratory in Tuxedo Park, New York, in the late 1930s. He established a top-secret defense laboratory at MIT and personally bankrolled pioneering research into new, high-powered radar detection systems that helped defeat the German Air Force and U-boats. With Ernest Lawrence, the Nobel Prize–winning physicist, he pushed Franklin Delano Roosevelt to fund research in nuclear fission, which led to the development of the atomic bomb. Jennet Conant, the granddaughter of James Bryant Conant, one of the leading scientific advisers of World War II, enjoyed unprecedented access to Loomis’ papers, as well as to people intimately involved in his life and work. She pierces through Loomis’ obsessive secrecy and illuminates his role in assuring the Allied victory.

    Newspapers proclaimed his genius in glowing personal profiles and quipped that “the doctor has been called” because the great man “has not invented anything since breakfast.” Starting with the first public demonstrations of the phonograph in 1878 and extending through the development of incandescent light, a power generation and distribution system to sustain it, and the first motion picture cameras—all achievements more astonishing in their time than we can easily grasp today—Edison’s name became emblematic of all the wonder and promise of the emerging age of technological marvels.But as Randall Stross makes clear in this critical biography of the man who is arguably the most globally famous of all Americans, Thomas Edison’s greatest invention may have been his own celebrity. Edison was certainly a technical genius, but Stross excavates the man from layers of myth-making and separates his true achievements from his almost equally colossal failures. How much credit should Edison receive for the various inventions that have popularly been attributed to him—and how many of them resulted from both the inspiration and the perspiration of his rivals and even his own assistants? How much of Edison’s technical skill helped him overcome a lack of business acumen and feel for consumers’ wants and needs?This bold reassessment of Edison’s life and career answers these and many other important questions while telling the story of how he came upon his most famous inventions as a young man and spent the remainder of his long life trying to conjure similar success. We also meet his partners and competitors, presidents and entertainers, his close friend Henry Ford, the wives who competed with his work for his attention, and the children who tried to thrive in his shadow—all providing a fuller view of Edison’s life and times than has ever been offered before. The Wizard of Menlo Park reveals not only how Edison worked, but how he managed his own fame, becoming the first great celebrity of the modern age.

     In 2007 and 2008, Time named Paul Allen, the cofounder of Microsoft, one of the hundred most influential people in the world.
