Seriously. Thank you so much. All of this info is unbelievably helpful and exactly the kind of direction I've been looking for. I started khan academy courses for multivariable calc and linear algebra for a refresher last week and this outline will help me immensely with my next steps. I just heard about Fast.ai in this panel conversation between Vivienne Ming, Jeremy Howard, and Peter Diamandis yesterday, and am excited to take the course. Dr. Ming's work has been super inspiring for me.
Thanks again for taking the time to respond so thoroughly! I will definitely take you up on that as questions come up through my studies :)
