This is quite an inane reason but I hate matrices and matrix operations. I loathe linear algebra. If you so much as whisper the word eigenvector or eigenvalue I may have to never speak to you again.
I never really believed in the school grade idea of “when will I ever use [X] topic?” With X usually being algebra. However, matrices was that topic for me. It is a great irony that now the basis for AI and ML is behind that hurdle. I am reading up on the basis for general purpose transformers and after the embedding step, we dot product each embedded column against the weight matrix.
I think I will need to go back to my engineering corner and face my fears cause it’s arriving a lot sooner than I expected.
