Hi, I’m wondering if there is a way to concatenate features of edge E and edges of E neighbor.

Suppose a directed graph with edges [(0,3), (3,0), (1,3), (3,1), (3,2), (2,3)], and then the edge embedding are concatenated as follows [ ((1,3),(3,0)); ((1,3),(3,2)); ((2,3),(3,0)); ((2,3),(3,1)); ((0,3),(3,1)); ((0,3),(3,2)) ]
