Machine Learning questions, answered

Do I need to be good at math to learn machine learning?

Some comfort with algebra and statistics helps, but you can grasp the core ideas first and deepen the math as you go.

Do I need to know how to code first?

Basic Python makes hands-on practice much easier. Learnr can build you a Python course first if you want that foundation.
