For each graph in the training set, the Graph2Vec package[8] is used to create 64-dimensional representations for the graph’s largest (highest node count) subgraph. This representation is used as 64 features for each graph. Also, 64-dimensional representations are taken of each subgraph of each graph, and a weighted average.
