I’ve been brushing up on tensor math and trying to reconcile familiar operations with Einsum Notation . Two great resources for this are srush’s Tensor Puzzles and pixqc’s Einsum Puzzles . They both use srush’s notebook puzzle format where a problem is setup for you in context and you have to code the solution within the notebook. Both are very easy to get up and running right on Colab. Whenever I come back to doing tensor math I have to refresh my mental model of all the different types of matrix operations. I thought it would be interesting to try to use Claude Code to build a tool for refreshing matrix/matrix and matrix/vector operations as quickly as possible. In particular, something that could help visualize fairly complex operations while learning a new architecture. At the time was I working through Building makemore Part 4: Becoming a Backprop Ninja , the fourth video in Andrej Karpathy’s great Neural Networks: Zero to Hero series. ...
