“Trivial” is relative, and in the context of this forum post and the audience that is reading it, running a basic neural net is unlikely a large hurdle for most here.

Hell, I’m not an ML practitioner and I almost never use python, and yet it took me maybe a day or two learn enough about covnet training to detect my dog on a home security camera.

All you have to do is multiply each weight and add up each node.

Pure bulk arithmetic is both simple and a perfect match for FHE.
