I gave a talk on how to organize an ML Study Jam at the joint event of Women Techmakers & Women in Data Science Lightning Talks meetup.
There are tons of great resources, for example, courses from tensorflow.org, Udacity, Coursera, MIT, Fast.ai, 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.
