Most models, including a GCN (Damonte and Cohen, 2019), GGNN (Beck et al., 2018), and GraphLSTM (Song et al., 2018), use a nonpairwise interaction function to represent the information to be aggregated from the neighborhoods.
they ignore the receiver node (i.e., the node to be updated), operating only on the sender node (i.e., the neighbor node) and the edge attribute (Battaglia et al., 2018).
