tailieunhanh - Machine Learning for Hackers

If you’re an experienced programmer interested in crunching data, this book will get you started with machine learning—a toolkit of algorithms that enables computers to train themselves to automate useful tasks. Authors Drew Conway and John Myles White help you understand machine learning and statistics tools through a series of hands-on case studies, instead of a traditional math-heavy presentation. | Case Studies and Algorithms to Get You Started for Hackers O REILLY Drew Conway John Myles white Programming Machine Learning Machine Learning for Hackers If you re an experienced programmer interested in crunching data this book will get you started with machine learning a toolkit of algorithms that enables computers to train themselves to automate useful tasks. Authors Drew Conway and John Myles white help you understand machine learning and statistics tools through a scries of hands-on case studies instead of a traditional mathheavy presentation. Each chapter focuses on a specific problem in machine learning such as classification prediction optimization and recommendation. Using the R programming language you ll learn how to analyze sample datasets and write simple machine learning algorithms. Machine Learning for Hackers is ideal for programmers from any background including business government and academic research. This book provides excellent case studies of a dozen different techniques in machine learning. With a focus on process rather than cookbooks or theory it should be accessible to anybody with a programming background and a quantitative mind.
