OTGNet: Towards Open Temporal Graph Neural Networks (ICLR 2023)

Open Temporal Graph	OTGNet

Introduction

This repository contains the code for paper: Towards Open Temporal Graph Neural Netwroks. This paper is accepted as ICLR 2023 notable-top-5% paper.

TL;DR: We propose a general and principled learning approach for open temporal graphs where the class set for nodes is open.

Setup

Clone the repo and build the environment

git clone https://github.com/tulerfeng/OTGNet.git
conda env create -f environment.yml
conda activate OTGNet

Dataset

Download raw data of three datasets and use the code in ./process_raw_data folder to process the raw data with GloVe

• Reddit
• Yelp
• Taobao

We also provide the processed datasets for direct use which could be downloaded at here.

Put the processed datasets in ./data folder

Training

Train model on the Reddit dataset

python run.py reddit

Train model on the Yelp dataset

python run.py yelp

Train model on the Taobao dataset

python run.py taobao
