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.

    a remarkable story—Leeza Gibbons, NBC-TV • Grippingly told ... a wonderful, powerful book—David Berner, Radio CKNW Vancouver • Reads with the pace of a taut thriller—George Henderson, Gloucestershire Citizen • Mesmerizing—Bob Stall, Vancouver Province. Now revised and updated. The amazing, true story of how medical authorities allow a family doctor to continue practising even after he begins living with a 15-year-old patient—and allegedly has sex with another girl in exchange for giving drugs to her father. The notorious doctor still carries on as before and a third patient complains about infamous conduct—until he silences her by putting out a contract for murder.

    In his latest book this message, though still present, has moved to the background. A Copernican revolution is in order, Lucado says: it is time to understand that life revolves around God, not ourselves. The God he describes is neither Santa Claus nor a kindly, reassuring grandpa. He is a God of glory and holiness, eternal and unchanging. "To seek God's glory is to pray, 'Thicken the air with your presence; make it misty with your majesty. Part heaven's drapes, and let your nature spill forth. God, show us God.' " Our role, once we have seen God's glory, is simply to reflect it. We do this by proclaiming his message, using our bodies the way he intended, trusting him in the midst of suffering and acknowledging him as the author of our success. Even our salvation "showcases God's mercy. It makes nothing of [our] effort but everything of his." Sterner generations of Christians memorized the answer to the first question in the Westminster Shorter Catechism: "Man's chief end is to glorify God and to enjoy him forever." Lucado brings this concept to life with his trademark breezy style, good humor, homey anecdotes and passion. His fans may be surprised by this new emphasis, but they will not be disappointed.

    Stuey Ungar, the son of a Jewish bookie on Manhattan's Lower East Side, dropped out of high school to become an underground card-table sensation, eventually taking out every top gin-rummy player on the East Coast. Bankrolled by the Genovese crime family, Stuey would soon travel around the country in search of new opponents and opportunities—including poker. He would go on to win the World Series of Poker a record three times. And then his luck began to run out. One of a Kind is the startling tale of a man who won at his game and lost control of his life. Whether tossing away his winnings at the racetrack or on a single roll of the dice, Stuey was notorious for gambling every single dollar in his pocket. Though he had won an estimated $30 million in his lifetime, Stuey had no bank account, not even a home address. He was found dead in a Vegas motel—with $800 in cash on his person, the only money he had left—at the age of forty-five. An intimate, authorized biography—Nolan Dalla was commissioned by Stuey in 1998 to pen his story, resulting in hundreds of hours of taped interviews and conversations—One of a Kind illuminates the dark genius of one of poker's most memorable figures.

    The black mass crashed through the local school. 144 people were killed. 116 were schoolchildren. Gaynor Madgwick was there. She was eight and severely injured. In this book, Gaynor tells her own story and interviews people affected by the day's events. "Gaynor Madgwick was pulled injured from one of the classrooms where her friends died. She was left behind to live out her life. This is her story, sad, sweet, sentimental, and authentic. I commend it to you." - Vincent Kane, Broadcaster "Gaynor Madgwick's sense of injustice is palpable in her clear, riveting account of this scandal and its human cost. Despite everything, however, she is not bitter and retains the quiet dignity that is, perhaps, the true and lasting legacy of Aberfan." - Frank Olding, Planet Magazine "Madgwick does not dwell too much on the politics of Aberfan, and this is left largely to an incisive introduction by the veteran broadcaster, Vincent Kane, who leaves us in no doubt where the responsibility lay for the disaster. Thankfully Madgwick has now found happiness after a troubled life, having had to live with the guilt of the survivor for all her life. And writing so sensitively has helped her to come to terms with what happened in 1966. This is certainly not an easy book to read, but as noted by Lord Snowdon, it should and must be read by all of us in memory of those who died, whilst not forgetting those who also survived this tragic event." - Richard E. Huws, Gwales

    An enlarged edition, including thirty pages of illustrations (sculpture and drawings) as well as Pound's later pieces on Gaudier, was brought out in 1970, and is now re-issued as an ND Paperbook. The memoir is valuable both for the history of modern art and for what it shows us of Pound himself, his ability to recognize genius in others and then to publicize it effectively. Would there today be a Salle Gaudier-Brzeska in the Musée de L'Art Moderne in Paris if Pound had not championed him? Gaudier's talent was impressive and his Vorticist aesthetic important as theory, but he was killed in World War I at the age of twenty-three, leaving only a small body of work. Pound knew Gaudier in London, where the young artist had come with his companion, the Polish-born Sophie Brzeska. whose name he added to his own. They were living in poverty when Pound bought Gaudier the stone from which the famous "hieratic head" of the poet was made. Pound arranged exhibitions and for the publication of Gaudier's manifestoes in Blast and The Egoist. And he wrote and sent packages to him in the trenches, where Gaudier––a sculptor to the last––carved a madonna and child from the butt of a captured German rifle, just two days before he died.

    1,000 coke or pepsi questions to ask your friends

    We're chasing the wrong things, asking the wrong questions, and polluting our minds. It's time to stop, it's time to resist and it's time to rethink the fundamental social blueprint that our lives are built upon.'As an 18-year-old, black, broke, lonely, insecure, university drop-out, from a bankrupt family, I wrote in my diary that I wanted to be a 'Happy Sexy Millionaire' by the age of 25. By 25 I was a multi-millionaire having created a business worth over $300m dollars. Ironically, in achieving everything I set out to, I learnt that I was wrong about almost everything... The world had lied to me. It lied to me about how you attain fulfilment, love and success, why those things matter, and what those words actually mean.In this book, I'll dismantle the most popular, unaddressed lies about happiness that we've been led to believe. I'll expose the source of these lies, examine the incentives that fuel them and replace them with a practical set of scientifically proven and unconventional ideas that will help you to live a truly fulfilled life, a life full of the love you seek and the success you deserve.'

    It may be hard to believe but it was against the background of all this that Eamonn won the WBU world welterweight and Commonwealth light welterweight titles. The author, Paul Gibson, has managed to decipher a very dark, very troubled, very flawed individual who happened to have an exceptional gift to box at the highest world level. The Lost Soul of Eamonn Magee reads like the screenplay of the kind of gritty rags-to-riches-to-rags boxing story that Hollywood producers seem to love.

    He describes his idyllic childhood in Eastern Tennessee, helping to operate his grandfolks' backyard nuclear plant. He explains how he sold his soul to the Devil to make him a better bluesman, and how the Devil tried to sell it back. And he reveals what happened when Neil Diamond invited him to dinner, and more importantly, why he had to wear a hardhat. Along the way he tackles the questions we've all asked ourselves from time to time, such as, which element did people breath before oxygen was discovered in 1774? (neon.) What's the difference between iron and lead? (There isn't one: ask anyone who has ever been hit in the head by a length of pipe.) And, if Jesus was a carpenter, "How come not a single example of his craftsmanship exists, not even a crude chest of drawers?" In the tradition of Woody Allen's "Without Feathers", "Things Snowball" is a comic, inventive book: subversive and entertaining.

    Although they did not win a trophy, they claimed something much more important and enduring: glory, and in industrial quantities. They were a bewitching fusion of futuristic attacking football, effortless Scandinavian cool and laid-back living. They played like angels and lived like you and I, and they were everyone's second team in the mid-1980s. The story of Danish Dynamite, as the team became known, is the story of a team of rock stars in a polyester Hummel kit.Heralding from a country with no real football history to speak of and a population of five million, this humble and likeable team was unique. Everymen off the field and superheroes on it, they were totally of their time, and their approach to the game was in complete contrast to the gaudy excess and charmless arrogance of today's football stars. That they ultimately imploded in spectacular style, with a shocking 5-1 defeat to Spain in the 1986 World Cup in a game that almost everyone expected them to win, only adds to their legend.For the first time in English, Danish Dynamite tells the story of perhaps the coolest team in football history, a team that had it all and blew it in spectacular style after a live-fast-die-young World Cup campaign. Featuring interviews with the players themselves, including Michael Laudrup, Preben Elkjær and Jesper Olsen, as well as with those who played or managed against them, this is a joyous celebration of one of the most life-affirming teams the world has ever seen.

    . . Nothing less than a major contribution to the scientific culture of this world." — The New York Times Book ReviewThis major survey of mathematics, featuring the work of 18 outstanding Russian mathematicians and including material on both elementary and advanced levels, encompasses 20 prime subject areas in mathematics in terms of their simple origins and their subsequent sophisticated developement. As Professor Morris Kline of New York University noted, "This unique work presents the amazing panorama of mathematics proper. It is the best answer in print to what mathematics contains both on the elementary and advanced levels."Beginning with an overview and analysis of mathematics, the first of three major divisions of the book progresses to an exploration of analytic geometry, algebra, and ordinary differential equations. The second part introduces partial differential equations, along with theories of curves and surfaces, the calculus of variations, and functions of a complex variable. It furthur examines prime numbers, the theory of probability, approximations, and the role of computers in mathematics. The theory of functions of a real variable opens the final section, followed by discussions of linear algebra and nonEuclidian geometry, topology, functional analysis, and groups and other algebraic systems.Thorough, coherent explanations of each topic are further augumented by numerous illustrative figures, and every chapter concludes with a suggested reading list. Formerly issued as a three-volume set, this mathematical masterpiece is now available in a convenient and modestly priced one-volume edition, perfect for study or reference."This is a masterful English translation of a stupendous and formidable mathematical masterpiece . . ." — Social Science

    With 60% of the book featuring entirely new material never before available on the website, Emails from an Asshole offers fans a fresh opportunity to revel in people's gullibility. Posing as a customer or seller, Lindsay responded to a variety of classified ads, making ridiculous offers to unsuspecting victims. Their responses, and the ensuing conversations, will have readers simultaneously laughing non-stop and gasping with disbelief.

    Pitch invaders aside, few of us get to experience that adrenalin rush. Of those who do make it as a professional footballer, even fewer realise the giddy heights of success. In the Illustrated History of Football: Hall of Fame, cartoonist David Squires returns to celebrate those who straddle the game like giants; those talented, determined souls who were juggling tennis balls in the back streets before they could talk. There’s more than one way to attain football immortality though, and Squires also turns his comic eye to the mavericks, the pioneers, the forgotten legends and the anti-heroes. From Pele to Meazza, Maradona to Socrates, you will be taken on an unforgettable journey through the good, the bad and the Hagi.

    Golden curled and boyishly handsome, his rise and fall as captain and player is unparalleled in our cricketing history. He played at least three innings that count as all-time classics, but it's his tearful resignation from the captaincy that is remembered. Insecure but arrogant, abrasive but charming; in Hughes' character were the seeds of his own destruction. Yet was Hughes' fall partly due to those around him, men who are themselves legends in Australia's cricketing history? Lillee, Marsh, and the Chappells, all had their agendas, all were unhappy with his selection and performance as captain—evidenced by Dennis Lillee's tendency to aim bouncers relentlessly at Hughes' head during net practice. As he traces the high points and the low, Chris Ryan sheds new and fascinating light on the cricket—and the cricketers—of the times.
