Interpretable Sparsification of Brain Graphs: Better Practices and Effective Designs for Graph Neural Networks

This code implements the following paper:

Interpretable Sparsification of Brain Graphs: Better Practices and Effective Designs for Graph Neural Networks

Requirement

• PyTorch
• PyTorch-Geometric
• numpy

Running our Method

To train our model, run the following script:

python ./src/main.py --method IGS --label_col $TASK_NAME --model $MODEL_NAME

where --label_col specifies the name of the task you want to work on and --model specifies the backbone model you want to use.

Data

We have provided the data in ./data directory. To generate your own random data splits, you could use process_data_splits from ./data/data_splits.py with specified arguments. The original raw data comes from the Wu-Minn HCP 1200 subjects data release, and we use pre-processed data from ConnectomeDB. To learn more about the task information, please visit this link.
