When Does Equivariance Help? Canonical Alignment in Neural Fluid Surrogates
The Anchored-Branched Geometric Algebra Transformer (AB-GATr), an E(3)-equivariant surrogate that efficiently predicts coupled surface and volume quantities, is introduced, and results support explicit equivariance for the evaluated hemodynamic tasks with natural orientation variation.
