I do like fast.ai for a lot of things. Their video production is very, very lacking though. I’ve tried to watch some of their DL courses and really they’re about as good as some stogy old non-tech savvy professor attempting to make an instructional video. Lots of echo, sound coming in an out, basically filmed from the back of an auditorium, etc. I can’t comment as much on the content as it was hard to get through. Some MIT OCW courses are similar. But from the fast ai content I’ve read, it’s very good.
An example of well done video is an Andrew Ng Coursers course. Great sound, great pacing, easy to follow like you’re on a zoom call with him directly, etc.
