With this hands-on guide, you'll learn how to write effective, idiomatic Python code by leveraging its best and possibly most neglected features. Author Luciano Ramalho takes you through Python's core language features and libraries, and shows you how to make your code shorter, faster, and more readable at the same time.Many experienced programmers try to bend Python to fit patterns they learned from other languages, and never discover Python features outside of their experience. With this book, those Python programmers will thoroughly learn how to become proficient in Python 3.This book covers:Python data model: understand how special methods are the key to the consistent behavior of objectsData structures: take full advantage of built-in types, and understand the text vs bytes duality in the Unicode ageFunctions as objects: view Python functions as first-class objects, and understand how this affects popular design patternsObject-oriented idioms: build classes by learning about references, mutability, interfaces, operator overloading, and multiple inheritanceControl flow: leverage context managers, generators, coroutines, and concurrency with the concurrent.futures and asyncio packagesMetaprogramming: understand how properties, attribute descriptors, class decorators, and metaclasses work"

    Machine learning provides these, developing methods that can automatically detect patterns in data and then use the uncovered patterns to predict future data. This textbook offers a comprehensive and self-contained introduction to the field of machine learning, based on a unified, probabilistic approach.The coverage combines breadth and depth, offering necessary background material on such topics as probability, optimization, and linear algebra as well as discussion of recent developments in the field, including conditional random fields, L1 regularization, and deep learning. The book is written in an informal, accessible style, complete with pseudo-code for the most important algorithms. All topics are copiously illustrated with color images and worked examples drawn from such application domains as biology, text processing, computer vision, and robotics. Rather than providing a cookbook of different heuristic methods, the book stresses a principled model-based approach, often using the language of graphical models to specify models in a concise and intuitive way. Almost all the models described have been implemented in a MATLAB software package—PMTK (probabilistic modeling toolkit)—that is freely available online. The book is suitable for upper-level undergraduates with an introductory-level college math background and beginning graduate students.

    Babies were plentiful, workers outnumbered retirees, and people aspiring towards the middle class yearned to own homes and cars. Companies didn't need to see any further than Europe and the United States to do well. Printed money was legal tender for all debts, public and private. We grew up learning how to "play the game," and we expected the rules to remain the same as we took our first job, started a family, saw our children grow up, and went into retirement with our finances secure.That world—and those rules—are over.By 2030, a new reality will take hold, and before you know it:- There will be more grandparents than grandchildren- The middle-class in Asia and Sub-Saharan Africa will outnumber the US and Europe combined- The global economy will be driven by the non-Western consumer for the first time in modern history- There will be more global wealth owned by women than men- There will be more robots than workers- There will be more computers than human brains- There will be more currencies than countriesAll these trends, currently underway, will converge in the year 2030 and change everything you know about culture, the economy, and the world.According to Mauro F. Guillen, the only way to truly understand the global transformations underway—and their impacts—is to think laterally. That is, using “peripheral vision,” or approaching problems creatively and from unorthodox points of view. Rather than focusing on a single trend—climate-change or the rise of illiberal regimes, for example—Guillen encourages us to consider the dynamic inter-play between a range of forces that will converge on a single tipping point—2030—that will be, for better or worse, the point of no return.2030 is both a remarkable guide to the coming changes and an exercise in the power of “lateral thinking,” thereby revolutionizing the way you think about cataclysmic change and its consequences.

    By following the teams that are inventing some of the world's best-loved toys, it spotlights the company's disciplined approach to harnessing creativity and recounts one of the most remarkable business transformations in recent memory. Brick by Brick reveals how LEGO failed to keep pace with the revolutionary changes in kids' lives and began sliding into irrelevance. When the company's leaders implemented some of the business world's most widely espoused prescriptions for boosting innovation, they ironically pushed the iconic toymaker to the brink of bankruptcy. The company's near-collapse shows that what works in theory can fail spectacularly in the brutally competitive global economy. It took a new LEGO management team – faced with the growing rage for electronic toys, few barriers to entry, and ultra-demanding consumers (ten-year old boys) – to reinvent the innovation rule book and transform LEGO into one of the world's most profitable, fastest-growing companies.  Along the way, Brick by Brick reveals how LEGO:- Became truly customer-driven by co-creating with kids as well as its passionate adult fans- Looked beyond products and learned to leverage a full-spectrum approach to innovation- Opened its innovation process by using both the "wisdom of crowds" and the expertise of elite cliques- Discovered uncontested, "blue ocean" markets, even as it thrived in brutally competitive red oceans- Gave its world-class design teams enough space to create and direction to deliver built a culture where profitable innovation flourishes Sometimes radical yet always applicable, Brick by Brick abounds with real-world lessons for unleashing breakthrough innovation in your organization, just like LEGO. Whether you're a senior executive looking to make your company grow, an entrepreneur building a startup from scratch, or a fan who wants to instill some of that LEGO magic in your career, you'll learn how to build your own innovation advantage, brick by brick.

    Enormously successful, the game inevitably raises the question: What is artificial life? And in this book--a chance for the devoted fan and the simply curious onlooker to see the world from the perspective of an original philosopher-engineer and intellectual maverick--Steve Grand proposes an answer.From the composition of the brains and bodies of artificial life forms to the philosophical guidelines and computational frameworks that define them, Creation plumbs the practical, social, and ethical aspects and implications of the state of the art. But more than that, the book gives readers access to the insights Grand acquired in writing Creatures--insights that yield a view of the world that is surprisingly antireductionist, antimaterialist, and (to a degree) antimechanistic, a view that sees matter, life, mind, and society as simply different levels of the same thing. Such a hierarchy, Grand suggests, can be mirrored by an equivalent one that exists inside a parallel universe called cyberspace.

    In Why Greatness Cannot Be Planned, Stanley and Lehman begin with a surprising scientific discovery in artificial intelligence that leads ultimately to the conclusion that the objective obsession has gone too far. They make the case that great achievement can't be bottled up into mechanical metrics; that innovation is not driven by narrowly focused heroic effort; and that we would be wiser (and the outcomes better) if instead we whole-heartedly embraced serendipitous discovery and playful creativity.Controversial at its heart, yet refreshingly provocative, this book challenges readers to consider life without a destination and discovery without a compass.

    Today, the utopia they sought to create is looking more dystopian than ever: from digital surveillance and the loss of privacy to the spreading of misinformation and hate speech to predatory algorithms targeting the weak and vulnerable to products that have been engineered to manipulate our desires. How did we get here? How did these once-scrappy and idealistic enterprises become rapacious monopolies with the power to corrupt our elections, co-opt all our data, and control the largest single chunk of corporate wealth—while evading all semblance of regulation and taxes?  In Don’t Be Evil, Financial Times global business columnist Rana Foroohar tells the story of how Big Tech lost its soul—and ate our lunch. Through her skilled reporting and unparalleled access—won through nearly thirty years covering business and technology—she shows the true extent to which behemoths like Google, Facebook, Apple, and Amazon are monetizing both our data and our attention, without us seeing a penny of those exorbitant profits. Finally, Foroohar lays out a plan for how we can resist, by creating a framework that fosters innovation while also protecting us from the dark side of digital technology.Praise for Don’t Be Evil “At first sight, Don’t Be Evil looks like it’s doing for Google what muckraking journalist Ida Tarbell did for Standard Oil over a century ago. But this whip-smart, highly readable book’s scope turns out to be much broader. Worried about the monopolistic tendencies of big tech? The addictive apps on your iPhone? The role Facebook played in Donald Trump’s election? Foroohar will leave you even more worried, but a lot better informed.”—Niall Ferguson, Milbank Family Senior Fellow at the Hoover Institution, Stanford, and author of The Square and the Tower

    At the center of this change are Apple and Google, two companies whose philosophies, leaders, and commercial acumen have steamrolled the competition. In the age of the Android and the iPad, these corporations are locked in a feud that will play out not just in the marketplace but in the courts and on screens around the world.     Fred Vogelstein has reported on this rivalry for more than a decade and has rare access to its major players. In Dogfight, he takes us into the offices and board rooms where company dogma translates into ruthless business; behind outsize personalities like Steve Jobs, Apple’s now-lionized CEO, and Eric Schmidt, Google’s executive chairman; and inside the deals, lawsuits, and allegations that mold the way we communicate. Apple and Google are poaching each other’s employees. They bid up the price of each other’s acquisitions for spite, and they forge alliances with major players like Facebook and Microsoft in pursuit of market dominance.     Dogfight reads like a novel: vivid nonfiction with never-before-heard details. This is more than a story about what devices will replace our phones and laptops. It’s about who will control the content on those devices and where that content will come from—about the future of media in Silicon Valley, New York, and Hollywood.

    It can almost be summed up by the button on every page: "Buy now with one click."Why has Amazon been so successful? Much of it has to do with Jeff Bezos, the CEO and founder, whose unique combination of character traits and business strategy have driven Amazon to the top of the online retail world.Richard Brandt charts Bezos's rise from computer nerd to world- changing entrepreneur. His success can be credited to his forward-looking insights and ruthless business sense. Brandt explains: Why Bezos decided to allow negative product reviews, correctly guessing that the earned trust would outweigh possible lost sales. Why Amazon zealously guards some patents yet freely shares others. Why Bezos called becoming profitable the "dumbest" thing they could do in 1997. How Amazon.com became one of the only dotcoms to survive the bust of the early 2000s. Where the company is headed next.Through interviews with Amazon employees, competitors, and observers, Brandt has deciphered how Bezos makes decisions. The story of Amazon's ongoing evolution is a case study in how to reinvent an entire industry, and one that anyone in business today ignores at their peril.

    In its sweeping survey of the history of Internet search technologies, its gossip about and analysis of Google, and its speculation on the larger cultural implications of a Web-connected world, it will likely receive attention from a variety of businesspeople, technology futurists, journalists, and interested observers of mid-2000s zeitgeist. This ambitious book comes with a strong pedigree. Author John Battelle was a founder of The Industry Standard and then one of the original editors of Wired, two magazines which helped shape our early perceptions of the wild world of the Internet. Battelle clearly drew from his experience and contacts in writing The Search. In addition to the sure-handed historical perspective and easy familiarity with such dot-com stalwarts as AltaVista, Lycos, and Excite, he speckles his narrative with conversational asides from a cast of fascinating characters, such Google's founders, Larry Page and Sergey Brin; Yahoo's, Jerry Yang and David Filo; key executives at Microsoft and different VC firms on the famed Sandhill road; and numerous other insiders, particularly at the company which currently sits atop the search world, Google. The Search is not exactly the corporate history of Google. At the book's outset, Battelle specifically indicates his desire to understand what he calls the cultural anthropology of search, and to analyze search engines' current role as the "database of our intentions"--the repository of humanity's curiosity, exploration, and expressed desires. Interesting though that beginning is, though, Battelle's story really picks up speed when he starts dishing inside scoop on the darling business story of the decade, Google. To Battelle's credit, though, he doesn't stop just with historical retrospective: the final part of his book focuses on the potential future directions of Google and its products' development. In what Battelle himself acknowledges might just be a "digital fantasy train", he describes the possibility that Google will become the centralizing platform for our entire lives and quotes one early employee on the weightiness of Google's potential impact: "Sometimes I feel like I am on a bridge, twenty thousand feet up in the air. If I look down I'm afraid I'll fall. I don't feel like I can think about all the implications." Some will shrug at such words; after all, similar hype has accompanied other technologies and other companies before. Many others, though, will search Battelle's story for meaning--and fast. --Peter Han

    With the Big Bang, it went from a state of unimaginable density to an all-encompassing cosmic fireball to a simmering fluid of matter and energy, laying down the seeds for everything from dark matter to black holes to one rocky planet orbiting a star near the edge of a spiral galaxy that happened to develop life. But what happens at the end of the story? In billions of years, humanity could still exist in some unrecognizable form, venturing out to distant space, finding new homes and building new civilizations. But the death of the universe is final. What might such a cataclysm look like? And what does it mean for us? Dr. Katie Mack has been contemplating these questions since she was eighteen, when her astronomy professor first informed her the universe could end at any moment, setting her on the path toward theoretical astrophysics. Now, with lively wit and humor, she unpacks them in The End of Everything, taking us on a mind-bending tour through each of the cosmos’ possible finales: the Big Crunch; the Heat Death; Vacuum Decay; the Big Rip; and the Bounce. In the tradition of Neil DeGrasse’s bestseller Astrophysics for People in a Hurry, Mack guides us through major concepts in quantum mechanics, cosmology, string theory, and much more, in a wildly fun, surprisingly upbeat ride to the farthest reaches of everything we know.

    Their discussion ranges from the history of the field's intellectual foundations to the most recent developments and applications.Reinforcement learning, one of the most active research areas in artificial intelligence, is a computational approach to learning whereby an agent tries to maximize the total amount of reward it receives when interacting with a complex, uncertain environment. In Reinforcement Learning, Richard Sutton and Andrew Barto provide a clear and simple account of the key ideas and algorithms of reinforcement learning. Their discussion ranges from the history of the field's intellectual foundations to the most recent developments and applications. The only necessary mathematical background is familiarity with elementary concepts of probability.The book is divided into three parts. Part I defines the reinforcement learning problem in terms of Markov decision processes. Part II provides basic solution methods: dynamic programming, Monte Carlo methods, and temporal-difference learning. Part III presents a unified view of the solution methods and incorporates artificial neural networks, eligibility traces, and planning; the two final chapters present case studies and consider the future of reinforcement learning.

    Taking us on a journey through every fundamental field of science, as well as the history of civilization, art, moral values, and the theory of political institutions, Deutsch tracks how we form new explanations and drop bad ones, explaining the conditions under which progress—which he argues is potentially boundless—can and cannot happen. Hugely ambitious and highly original, The Beginning of Infinity explores and establishes deep connections between the laws of nature, the human condition, knowledge, and the possibility for progress.

    Believers from Beijing to Buenos Aires see the potential for a financial system free from banks and governments. More than just a tech industry fad, Bitcoin has threatened to decentralize some of society’s most basic institutions.An unusual tale of group invention, Digital Gold charts the rise of the Bitcoin technology through the eyes of the movement’s colorful central characters, including an Argentinian millionaire, a Chinese entrepreneur, Tyler and Cameron Winklevoss, and Bitcoin’s elusive creator, Satoshi Nakamoto. Already, Bitcoin has led to untold riches for some, and prison terms for others.

    By weaving together their own research, interviews with pioneering scientists and Zach's trademark comics, the Weinersmiths investigate why these innovations are needed, how they would work, and what is standing in their way.
