I've taken both classes. You can take Andrew Ng's class with no prior AI experience. Though Math is a nice addition. Every concept is broken down and explained.

I've taken both classes. You can take Andrew Ng's class with no prior AI experience. Though Math is a nice addition. Every concept is broken down and explained. You actually get to build real models using python and numpy. This was probably the best course I took for an introduction. Yann LeCun class has a ton of information and you can easily get lost. I spent a great deal of time after hours trying to figure out what was being said in class. I still can't tell you what energy based models are. Not to take something away from the class, but you will need a whole lot of resources to come out learned in these classes. The option here is not either or. You will be better off starting with Andrew's class, then muster through Yann's.
