One-stop Source: 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.

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

Finally, I’ve added a section with links toa few miscellanous websitesthat 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.

Tutorials, Overviews, and (Individual) Lecture Notes

This section is fledgling at best, but was my real motivation in making this page. Archetypes include basically anything on distill.pub, good blog or medium posts, etc. Depth-first learning looks like a great access point here, but I haven’t gotten to do more than skim any of those, yet.

I wish that we had more publications like this. Pytorch Tutorials The tutorials put out by the pytorch developers are really fantastic. Easy to see why the community is growing so fast. Sebastian Ruder’s blog Sebastian has produced a lot of really great explanations, like the one on gradient descent methods I linked to above. He also maintains a website tracking progress on NLP benchmarks Berkeley AI Research (BAIR) Blog BAIR produces a lot of great research, and uses this blog to release more accessible presentations of their papers. Off the Convex Path Nice blog on machine learning and optimization.
