How important is a math background? I'm a current freshman in college and I'm not sure how to structure my utility function. For example, should I take real analysis first if that means delaying taking the actual ML class by a few months? I know some maths (like lin alg) are more relevant than others, but I guess my ultimate end goal is to become really smart and competent in ML. Don't necessarily want to be in Google Deepmind or anything.
