Dependencies

pip install dill tqdm tensorflow

Pipeline

• Match instances with motifs

# for cascade task
python preprocess.py
# for classification task
python prepare.py

• Training and evaluating

python main.py

Parameters

• To change dataset, modify the data_dir parameter in flags in main.py
• kernel.json under each dataset directory defines the motifs to be matched, modify it to customize the motifs
• For details of hyper-parameters, please refer to the comment in flags in main.py

Dataset

• graph.txt contains the edge list of the complete graph, graph is undirected
• train.txt contains the training data, each line is a data point, each data point is a subgraph
• train/subgraph/ contains all the data points, one data point per file, each represented as an edge list
• train/meta/ contains all the matched instances of motifs, one data point per file
