The second edition of the classic textbook introduction to statistical learning has come. New contents such as in-depth learning are available for free download

Stanford classic textbook 《The Element of Statistical Learning》（ abbreviation ESL） Statistical learning known as the frequency school 「 Bible 」, from Trevor Hastie、Robert Tibshirani、Jerome Friedman The three masters worked together to complete . This book introduces
neural network 、
Support vector machine 、 Classification tree and boosting、 Graph model 、 Random forest, etc
machine learning Algorithm , It can help readers understand
machine learning Algorithm overview .
But because this book involves a lot of formulas 、 Matrix derivation and many other difficult contents , It is more suitable for individuals with advanced training in Mathematical Science , And for beginners , It's difficult to learn , therefore ,Trevor Hastie They wrote another entry-level book 《Introduction to Statistical Learning with R（ Introduction to statistical learning ： be based on R application ）》（ISL）, Help more people get started as soon as possible .
ISL Weakens the details of mathematical derivation , Pay more attention to the application of methods , amount to ESL Guide to reading , Very popular among entry-level readers . Each chapter contains an experiment , use R Language implementation . These experiments provide readers with valuable practical experience .
at present , The book has been translated into many languages , Including Chinese 、 Italian 、 Japanese 、 Korean 、 Russian and Vietnamese .
Now? ,ISL Updated to the second edition （ISLRv2）, Compared to the first edition , The second edition adds
Deep learning （ The first 10 Chapter ）、 Survival analysis （ The first 11 Chapter ）、 Multiple tests （ The first 13 Chapter ）.ISLRv2 Some chapters of the first edition have also been greatly expanded ：
Naive Bayes And generalized linear model （ The first 4 Chapter ）, Bayesian additivity
Back to the tree （ The first 8 Chapter ）, Matrix completion （ The first 12 Chapter ）.
Besides ,ISLRv2 The whole... Has been updated R Code experiments .

Netizens strongly recommend ： very nice , This is a great introductory book .
Book Introduction
There are as many books as 597 page , common 13 Chapters , It mainly includes ：

Statistical learning ;

Linear regression ;

classification ;

Resampling Method ;

linear Model selection And Regularization ;

Nonlinear models ;

Tree based approach ;

Support vector machine ;

Deep learning ;

Survival analysis and deletion data ;

Unsupervised learning ;

Multiple tests .

To be specific , This book 2 This chapter introduces the basic terms and concepts behind statistical learning , In addition, it introduces k - Nearest neighbor classifier , This is a very simple method , Very effective in dealing with many problems .
The first 3 Zhang He 4 This chapter introduces the classical linear methods for regression and classification . In particular , The first 3 Chapter reviews
Linear regression , This is the basic starting point of all regression methods ; The first 4 Chapter discusses two of the most important classical classification methods , Logistic regression and linear discriminant analysis .
A core problem in all statistical learning situations is to choose the best method for a given application . therefore , The first 5 This chapter introduces cross validation and bootstrap, They can be used to estimate the accuracy of many different methods to select the best method .
The first 6 Many linear methods are considered in this chapter , Including classical and more modern linear methods , They provide a reference to the standard
Linear regression Potential improvements to , Including ridge regression 、 Principal component regression and Lasso etc. .
The remaining chapters are mainly nonlinear statistical learning . The first 7 First, some nonlinear methods are introduced , These methods can solve the problem of only one input variable , Then it shows how to use these methods to fit a nonlinear additive model with multiple inputs .
The first 8 In this chapter, the tree based method is studied , Include bagging、boosting And random forest .
The first 9 Describes the
Support vector machine The content such as .
The first 10 Describes the
Deep learning , This is a kind of non
Linear regression And the method of classification , In recent years, it has received wide attention .
The first 11 This chapter discusses survival analysis , This is a regression method , It is specially used when the output variable is deleted , That is, incomplete observation .
The first 12 This chapter introduces the unsupervised setup , There are input variables in the unsupervised setting , But no output variables . Specially , Principal component analysis is proposed 、k - Mean clustering and hierarchical clustering . Last , The first 13 This chapter discusses the very important topic of multiple hypothesis testing .
