详细介绍支持向量机、Boosting、最大熵、条件随机场等十个统计学习方法。

An Introduction to Statistical Learning provides an accessible overview of the field of statistical learning, an essential toolset for making sense of the vast and complex data sets that have emerged in fields ranging from biology to finance to marketing to astrophysics in the past twenty years. This book presents some of the most important modeling and prediction techniques, along with relevant applications. Topics include linear regression, classification, resampling methods, shrinkage approaches, tree-based methods, support vector machines, clustering, and more. Color graphics and real-world examples are used to illustrate the methods presented. Since the goal of this textbook is to facilitate the use of these statistical learning techniques by practitioners in science, industry, and other fields, each chapter contains a tutorial on implementing the analyses and methods presented in R, an extremely popular open source statistical software platform. Two of the authors co-wrote The Elements of Statistical Learning (Hastie, Tibshirani and Friedman, 2nd edition 2009), a popular reference book for statistics and machine learning researchers. An Introduction to Statistical Learning covers many of the same topics, but at a level accessible to a much broader audience. This book is targeted at statisticians and non-statisticians alike who wish to use cutting-edge statistical learning techniques to analyze their data. The text assumes only a previous course in linear regression and no knowledge of matrix algebra.

统计学习方法即机器学习方法，是计算机及其应用领域的一门重要学科。本书分为监督学 习和无监督学习两篇，全面系统地介绍了统计学习的主要方法。包括感知机、k 近邻法、朴素贝叶斯法、决策树、逻辑斯谛回归与最大熵模型、支持向量机、提升方法、EM 算法、隐马尔可夫模型和条件随机场，以及聚类方法、奇异值分解、主成分分析、潜在语义分析、概率潜在语义分析、马尔可夫链蒙特卡罗法、潜在狄利克雷分配和 PageRank 算法等。除有关统计学习、监督学习和无监督学习的概论和总结的四章外，每章介绍一种方法。叙述力求从具体问题或实例入手， 由浅入深，阐明思路，给出必要的数学推导，便于读者掌握统计学习方法的实质，学会运用。 为满足读者进一步学习的需要，书中还介绍了一些相关研究，给出了少量习题，列出了主要参考文献。 本书是统计机器学习及相关课程的教学参考书，适用于高等院校文本数据挖掘、信息检索及自然语言处理等专业的大学生、研究生，也可供从事计算机应用相关专业的研发人员参考。

This book is our attempt to bring together many of the important new ideas in learning, and explain them in a statistical framework. While some mathematical details are needed, we emphasize the methods and their conceptual underpinnings rather than their theoretical properties. As a result, we hope that this book will appeal not just to statisticians but also to researchers and practitioners in a wide variety of fields.
