I read a lot of math in ML papers, but I don't do any exercises, and maybe that's why I am not sure of myself. A very gradual collection of problems pertaining to linear algebra, calculus and statistics would be great. Something like Khan Academy, but the key point is to be gradual, so as not to terrify me before I get through it. Ideally such a training ground could guide students through problems based on exercise logs collected from other students, by creating an optimized curriculum. Anyone knows where to look?
