Clarification regarding distance function

[abdulwajid725]

Hi,
In the paper "Graph Neural Distance Metric Learning with GRAPH-BERT" your distance function d(G(i), G(j)) has fully connected layers in it.
Can you give more details about the fully connected layer.
Also I could not find the code for this paper, in this repository as directed in https://github.com/jwzhanggy/graph_bert_work

Thanks
