ML Resources

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. The organizatiion is as follows:

• Open Courses and Textbooks: Cover a fairly broad topic reasonably comprehensively, and would take weeks to months to work through start-to-finish.

• Tutorials, Overviews, and (Individual) Lecture Notes: Explain a specific topic extremely clearly, and take minutes to hours (or a few days tops) to work through from start-to-finish.

• Cheatsheets: Provide structured access to useful bits of information on the order of seconds.

Finally, I’ve added a section with links to a few miscellanous 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. I hope to use it to capture the best explanations of tricky topics that I have read online, to make it easier to re-learn them later when I inevitably forget. (In a perfect world, Chris Olah and/or distill.pub would just write an article on everything, but in the meantime I have to gather scraps from everywhere else.)

If you stumble upon this list and have suggestions for me to add (especially for the middle section!), please feel free to reach out! But I’m only trying to post things on here that I’ve read, so it may be caught in my to-read list for a while before it makes it on here. Of course, the source for this webpage is on github, so you can also just take it.

Open Courses and Textbooks

I’m trying to limit to this list to things that are legally accessible online, for free.
