i don’t think it’s that you’re dumb, i think it’s that you’re missing background knowledge the author expects, so it will take more time for you to understand.

I feel like I understand CS concepts and programming language theory well. But I’m having a hard time learning machine learning. Most of my experience is in software development and discrete math, where it looks like ML requires more calculus, linear algebra, and statistics. The formulas which use vector and matrix multiplication go over my head because i haven’t really internalized matrix algebra yet, these formulas are supposed to be trivial and intuitive but to me they’re not.
