The judges in these technical cases can be quite sophisticated and absolutely do learn terms of art. See Oracle v. Google (Java API case)
As I looked up the judge for this one(https://en.wikipedia.org/wiki/William_Alsup) who was a hobbyist basic programmer, one would need a judge who coded MNIST as a passtime hobby if that is the case.
a smart judge who is minimally tech savvy could learn to train a model to predict MNIST in a day or two
I thought that's what GPT was for.
"you are a helpful law assistant."
"You are a long-suffering clerk speaking to a judge who's sat the same federal bench for two decades and who believes 'everything is computer' constitutes a deep technical insight."
