You want to build AIs, but got stuck with matrix multiplication? Maybe you picked up a linear algebra textbook, but got stuck on “determinants”? This course is for you! I'll skip over the stuff you don't need (like eigenwotsits), and I'll add the things the textbooks don't cover, like tensors and broadcasting. By the end, you'll be able to follow ML tutorials like GPT from scratch.

The only prerequisite is that you’re comfortable coding with numbers and arrays. I emphasize Python code like [1,2] instead of math squiggles like $[\begin{array}{c}1\\ 2\end{array}]$. I emphasize intuition over proof. I motivate each concept with machine-learning examples.
