Overview

In this repository, we develop contrastive learning with augmentations for GNN pre-training (GraphCL, Figure 1) to address the challenge of data heterogeneity in graphs. Systematic study is performed as shown in Figure 2, to assess the performance of contrasting different augmentations on various types of datasets.

Experiments

Potential Issues

Some issues might occur due to the version mismatch. I collect them as follows (keep updating).

  • KeyError:'num_nodes' in unsupervised_TU: #36, #41
  • AttributeError: 'Data' object has no attribute 'cat_dim' in transferLearning_MoleculeNet_PPI: #13
  • Bugs in subgraph implementation: #24
  • Loss of negative values in transfer learning: #50
  • Obsolete url of TU-Dataset: #71
