Bandana: Masked Graph Autoencoder with Non-discrete Bandwidths

This is the official source code repo of paper "Masked Graph Autoencoder with Non-discrete Bandwidths" in TheWebConf(WWW) 2024.

We explore a new paradigm of topological masked graph autoencoders with non-discrete masking strategies, named "bandwidths". We verify its effectiveness in learning network topology by both theory and experiment.

Requirements

See requirements.txt.

Reproduction

See run.ipynb for our experiment results. You can either run the model by this Jupyter file or by commands below in the terminal:

Link prediction

python train_link.py --dataset=<dataset_name> --use_cfg --device=<gpu_id>

<dataset_name>: Cora, Citeseer, Pubmed, Photo, Computers, CS, Physics

By --use_cfg, the best hyperparameters in the config/<dataset_name>.yml file are used by default.

python train_link_ogb.py --dataset=<dataset_name> --use_cfg --device=<gpu_id>

<dataset_name>: ogbl-collab, ogbl-ppa

Node classification

python train_node.py --dataset=<dataset_name> --use_cfg --device=<gpu_id>

<dataset_name>: Cora, Citeseer, Pubmed, Photo, Computers, CS, Physics, Wiki-CS, ogbn-arxiv, ogbn-mag
