I get these questions a lot: "how do I organize an ML Study Jam"? "Where do I find the ML content"? So I gave this talk "How to Organize an ML Study Jam" at the North America GDE Summit 2019, Toronto Canada.
There are tons of great resources, for example, courses from tensorflow.org, Udacity, Coursera, MIT and Kaggle Learn.
Hopefully this helps you whether you are organizing an ML Study Jam for your meetup, a study group or study ML on your own.
