How do I, as a 14 year old learn machine learning and the mathematics involved? • /r/MachineLearning

You can actually enter machine learning with a lot of different states of mathematical knowledge. There are a lot of courses which try to reduce the requirements you need as much as possible and come from a very applied side (most of the MOOCs). Here you need the basic math to calculate some results, but it is more just well if we optimize this function then this will be the solution etc. You will be ready to apply a lot of the methods out there and maybe twist them so that they fit your dataset but it won't help you so much if you want do derive new models yourself or understand where these models came from. If you really want to understand the mathematical framework behind a lot of methods (which is quite beautiful, for example kernels/svms) then you probably will need a lot of high math and should just start with doing some linear algebra or analysis book (to find good starter books go to some good university website, check their linear algebra 1 or analysis 1 courses and see which books the professors recommend).
