Curvature Under Attack in hZACH-ViT: Gauge Symmetry, Boundary Saturation, and Adversarial Failure
A study of hZACH-ViT, a compact Vision Transformer with Euclidean, Poincaré, and spherical prototype heads, found that reducing Poincaré curvature from c=1 to c=0.1 improved clean MacroF1 in all 15 pa…
