Lecture 1 | Machine Learning (Stanford) - YouTube:
Two things of interest here:
The course itself: artificial intelligence is really interesting and increasingly relevant. This is the course, I believe, that set off Andrew Ng to create Coursera
Youtube.edu: I wasn't aware that YouTube created a .edu site. Pretty much the same, but what's interesting is that it allows 'playlists' to be generated in such a way that you can organize videos into self-contained courses.
