#einsum — Public Fediverse posts

🎩🤓 Look out, math nerds! The life's work of countless physicists has been distilled into a "simple trick" for backpropagating through #einsum, which we all know is basically just fancy #emoji math. Grab your #numpy and prepare to be dazzled by the groundbreaking revelation that i, j, and k were *not* just randomly chosen letters! 🙄🔍

This morning I had an operation to do on a 3000x3000 matrix. I start by writing a dirty old triple nested loop... estimated time by tqdm: 3h30.

Ok let's rewrite this as an einsum.

16 seconds.

Wait what?

Double checking everything on smaller matrices. Everything checks out 😮
