The Elements of Statistical Learning textbook is available for free. It is a classic, widely-used textbooks for statistics and machine learning. Here is a far from complete list of some of the topics:
- Supervised Learning
- Linear/Logistic Regression
- Regularization
- Model Selection
- Trees
- Neural Networks
- Support Vector Machines
- Random Forests
- Unsupervised Learning
- Clustering
As you can see, the book is quite extensive.
Note: This book has been available for a quite a while, but I realized I have not added a link to it on my blog.
