With the sophisticated algorithms in this book, you can write smart programs to access interesting datasets from other web sites, collect data from users of your own applications, and analyze and understand the data once you've found it.Programming Collective Intelligence takes you into the world of machine learning and statistics, and explains how to draw conclusions about user experience, marketing, personal tastes, and human behavior in general -- all from information that you and others collect every day. Each algorithm is described clearly and concisely with code that can immediately be used on your web site, blog, Wiki, or specialized application. This book explains:Collaborative filtering techniques that enable online retailers to recommend products or media Methods of clustering to detect groups of similar items in a large dataset Search engine features -- crawlers, indexers, query engines, and the PageRank algorithm Optimization algorithms that search millions of possible solutions to a problem and choose the best one Bayesian filtering, used in spam filters for classifying documents based on word types and other features Using decision trees not only to make predictions, but to model the way decisions are made Predicting numerical values rather than classifications to build price models Support vector machines to match people in online dating sites Non-negative matrix factorization to find the independent features in a dataset Evolving intelligence for problem solving -- how a computer develops its skill by improving its own code the more it plays a game Each chapter includes exercises for extending the algorithms to make them more powerful. Go beyond simple database-backed applications and put the wealth of Internet data to work for you. "Bravo! I cannot think of a better way for a developer to first learn these algorithms and methods, nor can I think of a better way for me (an old AI dog) to reinvigorate my knowledge of the details."-- Dan Russell, Google "Toby's book does a great job of breaking down the complex subject matter of machine-learning algorithms into practical, easy-to-understand examples that can be directly applied to analysis of social interaction across the Web today. If I had this book two years ago, it would have saved precious time going down some fruitless paths."-- Tim Wolters, CTO, Collective Intellect

    Wilczek’s groundbreaking work in quantum physics was inspired by his intuition to look for a deeper order of beauty in nature. In fact, every major advance in his career came from this intuition: to assume that the universe embodies beautiful forms, forms whose hallmarks are symmetry—harmony, balance, proportion—and economy. There are other meanings of “beauty,” but this is the deep logic of the universe—and it is no accident that it is also at the heart of what we find aesthetically pleasing and inspiring.Wilczek is hardly alone among great scientists in charting his course using beauty as his compass. As he reveals in A Beautiful Question, this has been the heart of scientific pursuit from Pythagoras, the ancient Greek who was the first to argue that “all things are number,” to Galileo, Newton, Maxwell, Einstein, and into the deep waters of twentiethcentury physics. Though the ancients weren’t right about everything, their ardent belief in the music of the spheres has proved true down to the quantum level. Indeed, Wilczek explores just how intertwined our ideas about beauty and art are with our scientific understanding of the cosmos.Wilczek brings us right to the edge of knowledge today, where the core insights of even the craziest quantum ideas apply principles we all understand. The equations for atoms and light are almost literally the same equations that govern musical instruments and sound; the subatomic particles that are responsible for most of our mass are determined by simple geometric symmetries. The universe itself, suggests Wilczek, seems to want to embody beautiful and elegant forms. Perhaps this force is the pure elegance of numbers, perhaps the work of a higher being, or somewhere between. Either way, we don’t depart from the infinite and infinitesimal after all; we’re profoundly connected to them, and we connect them. When we find that our sense of beauty is realized in the physical world, we are discovering something about the world, but also something about ourselves.Gorgeously illustrated, A Beautiful Question is a mind-shifting book that braids the age-old quest for beauty and the age-old quest for truth into a thrilling synthesis. It is a dazzling and important work from one of our best thinkers, whose humor and infectious sense of wonder animate every page. Yes: The world is a work of art, and its deepest truths are ones we already feel, as if they were somehow written in our souls.

    He is ultra competitive but never forgets to have fun. An immensely likeable man.' Damon HillThe world’s foremost designer in Formula One, Adrian Newey OBE is arguably one of Britain’s greatest engineers and this is his fascinating, powerful memoir.How to Build a Car explores the story of Adrian’s unrivalled 35-year career in Formula One through the prism of the cars he has designed, the drivers he has worked alongside and the races in which he’s been involved.A true engineering genius, even in adolescence Adrian’s thoughts naturally emerged in shape and form – he began sketching his own car designs at the age of 12 and took a welding course in his school summer holidays. From his early career in IndyCar racing and on to his unparalleled success in Formula One, we learn in comprehensive, engaging and highly entertaining detail how a car actually works. Adrian has designed for the likes of Mario Andretti, Nigel Mansell, Alain Prost, Damon Hill, David Coulthard, Mika Hakkinen, Mark Webber and Sebastian Vettel, always with a shark-like purity of purpose: to make the car go faster. And while his career has been marked by unbelievable triumphs, there have also been deep tragedies; most notably Ayrton Senna’s death during his time at Williams in 1994.Beautifully illustrated with never-before-seen drawings, How to Build a Car encapsulates, through Adrian’s remarkable life story, precisely what makes Formula One so thrilling – its potential for the total synchronicity of man and machine, the perfect combination of style, efficiency and speed.

    It was written by the game's first level designer, John Staats, from notes he took during WoW's creation. The WoW Diary explains why developers do things and debunks popular myths about the games industry. In great detail he covers the what it took to finish the project; the surprises, the arguments, the mistakes, and Blizzard's formula for success.

    interstate system changed the face of our country. The Big Roads charts the creation of these essential American highways. From the turn-of-the-century car racing entrepreneur who spurred the citizen-led “Good Roads” movement, to the handful of driven engineers who conceived of the interstates and how they would work—years before President Eisenhower knew the plans existed—to the protests that erupted across the nation when highways reached the cities and found people unwilling to be uprooted in the name of progress, Swift follows a winding, fascinating route through twentieth-century American life.  How did we get from dirt tracks to expressways, from main streets to off-ramps, from mud to concrete and steel, in less than a century? Through decades of politics, activism, and marvels of engineering, we recognize in our highways the wanderlust, grand scale, and conflicting notions of citizenship and progress that define America.

    In this unconventional introduction, physicist Leonard Susskind and hacker-scientist George Hrabovsky offer a first course in physics and associated math for the ardent amateur. Unlike most popular physics books—which give readers a taste of what physicists know but shy away from equations or math—Susskind and Hrabovsky actually teach the skills you need to do physics, beginning with classical mechanics, yourself. Based on Susskind's enormously popular Stanford University-based (and YouTube-featured) continuing-education course, the authors cover the minimum—the theoretical minimum of the title—that readers need to master to study more advanced topics.An alternative to the conventional go-to-college method, The Theoretical Minimum provides a tool kit for amateur scientists to learn physics at their own pace.

    In 1997, she wroteClose to the Machine, the now classic and still definitive account of life as a coder at the birth of what would be a sweeping technological, cultural, and financial revolution.The intervening twenty years has seen, among other things, the rise of the Internet, the ubiquity of once unimaginably powerful computers, and the thorough transformation of our economy and society—as Ullman’s clique of socially awkward West Coast geeks became our new elite, elevated for and insulated by a technical mastery that few could achieve.In Life in Code, Ullman presents a series of essays that unlock and explain—and don’t necessarily celebrate—how we got to now, as only she can, with a fluency and expertise that’s unusual in someone with her humanistic worldview, and with the sharp insight and brilliant prose that are uniquely her own. Life in Code is an essential text toward our understanding of the last twenty years—and the next twenty.

    The city had been dumping barely treated sewage into its harbor, coating the seafloor with a layer of "black mayonnaise." Fisheries collapsed, wildlife fled, and locals referred to floating tampon applicators as "beach whistles." But before the plant could start operating, a team of divers had to make a perilous journey to the end of a 10-mile tunnel-devoid of light and air-to complete the construction. Five went in; two never came out. Drawing on hundreds of interviews and thousands of documents, award-winning reporter Neil Swidey re-creates the tragedy and its aftermath in an action-packed narrative. The climax comes when the hard-partying DJ Gillis and his friend Billy Juse trade jobs at a pivotal moment in the mission, sentencing one diver to death and the other to a trauma-induced heroin addiction that eventually lands him in prison. Trapped Under the Sea reminds us that behind every bridge, highway, dam, and tunnel-behind the infrastructure that makes modern life possible-lies unsung bravery and extraordinary sacrifice.

    However, according to Hofstadter, the formal system that underlies all mental activity transcends the system that supports it. If life can grow out of the formal chemical substrate of the cell, if consciousness can emerge out of a formal system of firing neurons, then so too will computers attain human intelligence. Gödel, Escher, Bach is a wonderful exploration of fascinating ideas at the heart of cognitive science: meaning, reduction, recursion, and much more.

    In the meantime, she lived in a $17-a-night motel with her dog, Otis, and waited tables at a low-rent Thai restaurant. One day, one of her regular customers told her about a job she thought Beth would be perfect for and sent her to see Dink, of Dink Inc. Dink was a professional sports gambler—one of the biggest in Vegas. He was looking for a right-hand man—someone who would show up on time, who had a head for numbers, and who didn’t steal. She got the job.Lay the Favorite is the story of Beth Raymer’s years in the high-stakes, high-anxiety world of sports betting—a period that saw the fall of the local bookie and the rise of the freewheeling, unregulated offshore sports book, and with it the elevation of sports betting in popular culture. As the business explodes, Beth rises—from assistant to expert, trusted and seasoned enough to open an offshore booking office in the Caribbean with a few associates, men who leave their families up north to make a quick killing, while donning new tropical personas fueled by abundant drugs and local girlfriends, and who one by one succumb to their vices. They lie, cheat, steal, and run, until Beth is the last man standing.Beth Raymer is a natural storyteller: funny, charming, and fully awake to the ironies around her. But she is also a keen and compassionate observer of the adrenaline-addicted, rougish types who become her mentors, her enemies, her family. Raymer brings to life a world that teems with pathos and ecstasy in this wild picaresque that also tells the story of a young woman’s crazy, sexy, most unlikely coming-of-age.

    Their initial optimism is short-lived, however, as the ice field slowly thickens, encasing the ship Endurance in a death-grip, crushing their craft, and marooning 28 men on a polar ice floe.In an epic struggle of man versus the elements, Shackleton leads his team on a harrowing quest for survival over some of the most unforgiving terrain in the world.

    prison system, tracking down a chameleon con artist in Europe, or riding in a cyclone-tossed skiff with a scientist hunting the elusive giant squid, David Grann revels in telling stories that explore the nature of obsession and that piece together true and unforgettable mysteries.Each of the dozen stories in this collection reveals a hidden and often dangerous world and, like Into Thin Air and The Orchid Thief, pivots around the gravitational pull of obsession and the captivating personalities of those caught in its grip. There is the world's foremost expert on Sherlock Holmes who is found dead in mysterious circumstances; an arson sleuth trying to prove that a man about to be executed is innocent, and sandhogs racing to complete the brutally dangerous job of building New York City's water tunnels before the old system collapses. Throughout, Grann's hypnotic accounts display the power-and often the willful perversity-of the human spirit.Compulsively readable, The Devil and Sherlock Holmes is a brilliant mosaic of ambition, madness, passion, and folly.

    Manning and his team at NASA's Jet Propulsion Laboratory, tasked with designing a lander many times larger and more complex than any before, faced technical setbacks, fights over inadequate resources, and the challenges of leading an army of brilliant, passionate, and often frustrated experts.Manning's fascinating personal account--which includes information from his exclusive interviews with leading Curiosity scientists--is packed with tales of revolutionary feats of science, technology, and engineering. Readers experience firsthand the disappointment at encountering persistent technical problems, the agony of near defeat, the sense of victory at finding innovative solutions to these problems, the sheer terror of staking careers and reputations on a lander that couldn't be tested on Earth, and the rush of triumph at its successful touchdown on Mars on August 5, 2012. This is the story of persistence, dedication, and unrelenting curiosity.

    In this heartfelt and passionate book, Frenkel shows that mathematics, far from occupying a specialist niche, goes to the heart of all matter, uniting us across cultures, time, and space.Love and Math tells two intertwined stories: of the wonders of mathematics and of one young man’s journey learning and living it. Having braved a discriminatory educational system to become one of the twenty-first century’s leading mathematicians, Frenkel now works on one of the biggest ideas to come out of math in the last 50 years: the Langlands Program. Considered by many to be a Grand Unified Theory of mathematics, the Langlands Program enables researchers to translate findings from one field to another so that they can solve problems, such as Fermat’s last theorem, that had seemed intractable before.At its core, Love and Math is a story about accessing a new way of thinking, which can enrich our lives and empower us to better understand the world and our place in it. It is an invitation to discover the magic hidden universe of mathematics.
