ai;dr

MLP trained on 8 questions achieves ~0.3cm height error, ~0.3kg weight error, and ~3-4cm for bust/waist/hips measurements.

100% Agree.

I wonder if there is a mitigation strategy for this. Is there a way to make (human-made-art) scraping robustly difficult, while leaving human discovery and exploration intact?

This is very cool and crosses paths with a few projects I've been working on recently. - implementing a ReLU network in Blender, mostly for visualization - applying the Riemann-Schwarz mapping theorem to discrete radiance fields - solving a spherical-elliptical optics dilemma in perspective projection Your project dovetails spectacularly with this yet you've tackled the core chain of geometry problems "in the opposite direction". It seems I'll have to pick a different thesis topic, but I'd love to pick your brain about it.
