GraphPrompt

We provide the code (in pytorch) and datasets for our paper "GraphPrompt: Unifying Pre-Training and Downstream Tasks for Graph Neural Networks", which is accepted by WWW2023.

We Further extend GraphPrompt to GraphPrompt+ by enhancing the pre-training and prompting stages "Generalized Graph Prompt: Toward a Unification of Pre-Training and Downstream Tasks on Graphs" which is accepted by IEEE TKDE, the code and datasets are publicly available (https://github.com/gmcmt/graph_prompt_extension).

Description

The repository is organised as follows:

• data/: contains data we use.
• graphdownstream/: implements pre-training and downstream tasks at the graph level.
• nodedownstream/: implements downstream tasks at the node level.
• convertor/: generate raw data.

Package Dependencies

• cuda 11.3
• dgl0.9.0-cu113
• dgllife

Running experiments

Graph Classification

Default dataset is ENZYMES. You need to change the corresponding parameters in pre_train.py and prompt_fewshot.py to train and evaluate on other datasets.

Pretrain:

• python pre_train.py

Prompt tune and test:

• python prompt_fewshot.py

Node Classification

Default dataset is ENZYMES. You need to change the corresponding parameters in prompt_fewshot.py to train and evaluate on other datasets.

Prompt tune and test:

• python run.py
