Thanks! How does ML compare to the AI class? I considered taking both, but I was worried overextending my leisure-time learning budget.
It comes off a bit more hands on with regards to implementation. For example there was a lot of talk about efficiency and the 5th segment is a quick tutorial for Octave, since programming assignments are also part of the class. The interface of the website is better currently (and for example the slides used in the presentations are available for download). The homework section which is just review for now can be taken almost as many times as you like (the variables of the problems change ala Khan Academy) and you get instant feedback. Ng comes off a bit ...
Here you go: http://www.ai-class.com/
They're still working out kinks in the site, and no homework is up yet, but the initial set of lectures (really really basic "what is AI/welcome to the first day of class" type stuff is up), so if you signed up, then sign in and hopefully the site will work for you.
