Excellent explanation as always! The only thing I did not understand is in 15:47 what do you mean by axis aligned? I don't see any difference between QDA and Naive Bayes plots. The circles in both can be ellipse like or circle like.

[@kamperh]

No this is a good question. The point is that, while both QDA and naive Bayes can have ellipses, that for naive Bayes these ellipses will have to lie perfectly horizontal or vertical. With QDA, your ellipse can be slanted. I hope that makes sense!

​@@kamperh yes it makes sense :) thank you!
