I have read many ML papers, and even understood a few of them. My understanding of calculus is beyond weak: I know what a derivative (and a partial derivative!) is, and what integration is, but God help me if I have to do one. I've got a pretty firm grasp on linear algebra though. I don't think calculus plays into modern ML that much.
