Description

This is the repository for the IJCAI-19 paper Hierarchical Graph Convolutional Networks for Semi-supervised Node Classification.

Requirements

• Tensorflow (1.9.0)
• networkx

Usage

You can conduct node classification experiments on citation network (Cora, Citeseer or Pubmed) with the following commands:

python train.py --dataset cora --epochs 60 --early_stopping 1000 --coarsen_level 4 --dropout 0.85 --weight_decay 7e-4 --hidden 32 --node_wgt_embed_dim 8 --seed1 156 --seed2 136

python train.py --dataset citeseer --epochs 200 --early_stopping 60 --coarsen_level 4 --dropout 0.85 --weight_decay 7e-4 --hidden 30 --node_wgt_embed_dim 15 --seed1 156 --seed2 156

python train.py --dataset pubmed --epochs 250 --early_stopping 1000 --coarsen_level 4 --dropout 0.85 --weight_decay 7e-4 --hidden 30 --node_wgt_embed_dim 8 --seed1 156 --seed2 136
