I mainly learned linear algebra via hands-on 3D graphics, and have a hard time thinking about a matrix as anything other than 4x4 and representing a linear transform...

How much do you even think about explicit matrix math when doing high-level ML?

3D graphics is so much more than the basic transforms. Add in all the deformation systems blending together, and those often being physics driven off the animation. You all have seen modern VFX, right? That is not basic 4x4 transforms.

I’ve not done high level ML, but I’ve done introductory ML and the truth is while the input space and the output space can have N and M dimensions, there’s not a lot of constraints involved. The matrix there are more randoms.

The whole ML field is basically about starting from random points and trying to find useful shapes and constraints. Basically like trying to get object likeness in clouds
