基本説明
This comprehensive textbook concentrates on clustering (a required step for any unsupervised data), data preparation, and data mining tools, focusing on those algorithms which have proven successful in data mining projects. In addition, the book analyzes the most popular data mining methods and presents the most freely available commercial data mining tools.
Full Description
"If you torture the data long enough, Nature will confess," said 1991 Nobel-winning economist Ronald Coase. The statement is still true. However, achieving this lofty goal is not easy. First, "long enough" may, in practice, be "too long" in many applications and thus unacceptable. Second, to get "confession" from large data sets one needs to use state-of-the-art "torturing" tools. Third, Nature is very stubborn — not yielding easily or unwilling to reveal its secrets at all. Fortunately, while being aware of the above facts, the reader (a data miner) will find several efficient data mining tools described in this excellent book. The book discusses various issues connecting the whole spectrum of approaches, methods, techniques and algorithms falling under the umbrella of data mining. It starts with data understanding and preprocessing, then goes through a set of methods for supervised and unsupervised learning, and concludes with model assessment, data security and privacy issues. It is this specific approach of using the knowledge discovery process that makes this book a rare one indeed, and thus an indispensable addition to many other books on data mining. To be more precise, this is a book on knowledge discovery from data. As for the data sets, the easy-to-make statement is that there is no part of modern human activity left untouched by both the need and the desire to collect data. The consequence of such a state of affairs is obvious.
