A comprehensive list of Machine Learning Resources: Open Courses, Textbooks, Tutorials, Cheat Sheets and more

This is a not-particularly-systematic attempt to curate a handful of my favorite resources for learning statistics and machine learning. This isn't meant to be comprehensive, and in fact is still missing the vast majority of my favorite explainers. Rather, it's just a smattering of resources I've found myself turning to multiple times and thus would like to have in one place. Finally, I've added a section with links to a few miscellaneous websites that often produce great content. Of the above, the second section is both the most incomplete and the one that I am most excited about.
