# DGL Implementations of P-GNN
|
|
|
|
This DGL example implements the GNN model proposed in the paper [Position-aware Graph Neural Networks](http://proceedings.mlr.press/v97/you19b/you19b.pdf). For the original implementation, see [here](https://github.com/JiaxuanYou/P-GNN).

## Requirements
|
|
|
|
The codebase is implemented in Python 3.8. For version requirement of packages, see below.
|
|
|
|
```
|
|
dgl 0.7.2
|
|
numpy 1.21.2
|
|
torch 1.10.1
|
|
networkx 2.6.3
|
|
scikit-learn 1.0.2
|
|
```
|
|
|
|
## Instructions for experiments
|
|
|
|
### Link prediction
|
|
|
|
```bash
|
|
# Communities-T
|
|
python main.py --task link
|
|
|
|
# Communities
|
|
python main.py --task link --inductive
|
|
```
|
|
|
|
### Link pair prediction
|
|
|
|
```bash
|
|
# Communities
|
|
python main.py --task link_pair --inductive
|
|
```
|
|
|
|
## Performance
|
|
|
|
### Link prediction (Grid-T and Communities-T refer to the transductive learning setting of Grid and Communities)
|
|
|
|
| Dataset | Communities-T | Communities |
|
|
| :------------------------------: | :-----------: | :-----------: |
|
|
| ROC AUC ( P-GNN-E-2L in Table 1) | 0.988 ± 0.003 | 0.985 ± 0.008 |
|
|
| ROC AUC (DGL: P-GNN-E-2L) | 0.984 ± 0.010 | 0.991 ± 0.004 |
|
|
|
|
### Link pair prediction
|
|
|
|
| Dataset | Communities |
|
|
| :------------------------------: | :---------: |
|
|
| ROC AUC ( P-GNN-E-2L in Table 1) | 1.0 ± 0.001 |
