GraphConv operator for graph classification

[evantianzg]

Hi

I am using GraphConv operator, which is from the "Weisfeiler and Leman Go Neural: Higher-order Graph Neural Networks" paper, for graph classification. This paper proposes k-gnn.

My question is how should I call the model using GraphConv operator for graph classification? k-GNN or k-GCN? or GraphGCN? If using k-GNN or k-GCN? What is the specific value of k in the GraphConv operator?
