Thanks; this is a very helpful and informative reply. Are you referring to DeepLearning.AI?
I started with this 3 part course - https://www.coursera.org/specializations/machine-learning-in.... I think the same course is available at deeplearning.ai as well, I'm not sure, but I found coursera's format of ~5 min videos on the phone app very helpful (with speed-up options). I was a new mother and didn't have continuous hours of time back then. I could watch these videos while brushing, etc. It helped me to not quit. After a point I was hooked & baby also grew up a bit and I gradually acquired more time and energy for learning ML. :)
fastai is also amazing, but it's made of 1.5 hour videos, and is more freeflowing. By the time I even figured out where we stopped last time, my time would sometimes be up. It was very discouraging because of this. But later, once I got a little more time & some basic understanding from Andrew Ng, I was able to attempt fastai.
