(3) fuzzy element and bond level, a whitened molecular graph that all bond types are changed In Diff-Shape, GrCN is implemented as illustrated in Figure for a given time step 𝑡. A pre-trained MIDI model is employed as the prior model. As mentioned in the previous section, the embedding blocks of the trainable copy of prior model are utilized to process the condition 3D graph 𝐺 52 , each attaching a zero MLP layer and additionally, two MLPs are used for the scalar features 𝑉, 𝐸 and one E3 MLP for the 𝑅 set. The E3 MLP can maintain the coordinate equivariance for 𝑅 = {𝑟 0 … 𝑟 ; } by scaling each 𝑟 : relative to its norm ‖𝑟 : ‖ , as shown in Eq (8).
