Hi there,

I would like to clarify the value of the edge embedding when the value in D (the feature matrix) of that specific edge is missing in the bipartite graph. And what is the network utilised for O_edge to obtain a prediction of D_hat.

Thanks

No edge exists for the missing values. The edges are only built between observation and feature nodes with known feature values. O_edge is a network taking input of the concatenation of one observation node embedding and one feature node embedding and outputting the predicted feature value.
