A permutation-equivariant transformer trained on self-supervised oracle trajectories from scrambled expressions achieves near-perfect simplification rates for dilogarithms and 100% success on 5-point gluon scattering amplitudes with over 200 terms.
A pre-trained contrastive encoder [18, 27] computes an embedding for each numerator term, and pairwise cosine 11 similarities identify groups of terms likely to simplify to- gether
