r/artificial - Recommendation on Self-Teaching Math, AI, Data Science in 14 months

On Linear Algebra, it's rather rusty as it was a sudden leap into proof-heavy classes, so I didn't quite get what was going on most of the time. I have gone through an intro class on ML and Optimization as well (Rather superficial concepts without much exercises). I am going through a gap year - don't wanna be paying a hefty amount for zoom-classes next study year - so will be class-free for approximately 14 months. Personally aiming to devote 5 hours a day, 6 days a week.
