This repository contains the code package for the TNNLS paper:
A Synergistic Approach for Graph Anomaly Detection with Pattern Mining and Feature Learning.
Authors: Tong Zhao (tzhao2@nd.edu), Tianwen Jiang, Neil Shah, and Meng Jiang.
and the CIKM'20 paper:
Error-Bounded Graph Anomaly Loss for GNNs.
Authors: Tong Zhao (tzhao2@nd.edu), Chuchen Deng, Kaifeng Yu, Tianwen Jiang, Daheng Wang, and Meng Jiang.
This code package was developed with Python 3.6.8 and PyTorch 1.0.1.post2.
A detailed dependencies list can be found in requirements.txt and can be installed by:
pip install -r requirements.txt
Data files are located at /data/[dataset]/, a simple example of loading the data can be found here. Specifically, [dataset]_graph_u2p.pkl is the pickled sparse adjacency matrix (csr_matrix) and [dataset]_labels_u.pkl is the pickled user labels.
To train the model, run
python -m src.main
list of arguments can be found at here.
