I want to understand better how LLMs work. As one of the steps, I started watching videos about Transformers (the letter T in GPT :D). Pretty quickly I realized I don’t remember Linear Algebra from my university course so well.
So as a refresher I went through the full Essence of Linear Algebra course by 3Blue1Brown - and it was actually fun, because the author brings geometric interpretations of Linear Algebra. Vectors, matrices, eigenvalues - everything clicks differently when you can see it.
Highly recommended if you want to revisit the fundamentals before diving into ML/AI internals.
