To install all dependencies:
pip install -r requirements.txt
Anomalies have been injected into three datasets under the ./dataset directory.
Please refer to GRAND-Lab/CoLA for graph anomaly injection.
To train and evaluate on Cora:
python run.py --expid 1 --device cuda:0 --runs 1 --alpha 0.8
To train and evaluate on Citeseer:
python run.py --dataset citeseer --expid 2 --device cuda:0 --runs 1 --alpha 0.6
To train and evaluate on Pubmed:
python run.py --dataset pubmed --expid 3 --device cuda:0 --runs 1 --alpha 0.8 --negsamp_ratio_patch 6 --negsamp_ratio_context 1
