CSGNN

A PyTorch implementation for the paper below:
Cost Sensitive GNN-based Imbalanced Learning for Mobile Social Network Fraud Detection

Running CSGNN

To run the code, you need to have at least Python 3.7 or later versions.
1.In CSGNN/data directory，rununzip BUPT.zip and unzip Sichuan.zip to unzip the datasets;
2.Run python data_process.py to generate Sichuan and BUPT dataset in DGL;
3.-Run python main.py --config ./config/csgnn_sichuan.yml to run CSGNN with default settings on Sihcuan dataset;
-Run python main.py --config ./config/csgnn_bupt.yml to run CSGNN with default settings on BUPT dataset.

Repo Structure

The repository is organized as follows:

• data_process.py: convert raw node features and adjacency matrix to DGL dataset;
• main.py: training and testing CSGNN;
• model.py: CSGNN model implementations;
• utils.py: utility functions.
