While in a one-layer ACE, all clusters with central atom i would be considered, the MPNN formalism sparsifies this to only include walks along the graph (the topology of which is induced by local cutoffs) of length T that end on atom i. In practice, for typical settings of T, rcut...

As the nodes of the molecular graph represent the 3D coordinates of atoms, we are interested in additional equivariance with respect to the Euclidean group E(3) or rigid transformations. An E(3)-equivariant GNN (EGNN) satisfies EGNN(ΠXA + b) = Π EGNN(X)A + b for an orth...
previous work24. To train joint probability models in the all-atom scenario, it was necessary to scale down the coordinates (and corresponding distance cut-offs) by a factor of 0.2 instead to avoid introducing too many edges in the graph near the end of the diffusion process att = T....
study of their performance, proving that they do not suffer from barren plateaus, quickly reach overparametrization, and generalize well from small amounts of data. To verify our results, we perform numerical simulations for a graph state classification task. Our work provides theoretical guarantees ...
