PSI

Official Implementation of 'Partial Subgraph InfoMax (PSI)' from 'Models and Benchmarks for Representation Learning of Partially Observed Subgraphs', 31st ACM International Conference on Information and Knowledge Management (CIKM 2022, Short Papers Track).

BibTeX

TBA

Installation

bash PSI/install.sh ${CUDA, optional, default is cu102.}

• If you have any trouble installing PyTorch Geometric, please install PyG's dependencies manually.
• Codes are tested with python 3.7.9 and nvidia/cuda:10.2-cudnn8-devel-ubuntu18.04 image.
• PYG's FAQ might be helpful.

Basics

• The main train/test code is in PSI/main.py.
• If you want to see hyperparameter settings, refer to PSI/args.yaml and PSI/arguments.py.

Run

python -u PSI/main.py \
    --dataset-name FNTN \
    --custom-key BIE2D2F64-ISI-X-GB-PGA \
    --gpu-ids 0 \
    --dataset-path /mnt/nas2/GNN-DATA/

GPU Setting

There are three arguments for GPU settings (--num-gpus-total, --num-gpus-to-use, --gpu-ids). Default values are from the author's machine, so we recommend you modify these values from PSI/args.yaml or by the command line.

• --num-gpus-total (default 4): The total number of GPUs in your machine.
• --num-gpus-to-use (default 1): The number of GPUs you want to use.
• --gpu-ids (default: [0]): The ids of GPUs you want to use.
