NODESAFE: Bounded and Uniform Energy-based Node-level Out-of-distribution Detection on Graphs

Dependence

• Ubuntu 20.04
• Cuda 12.1
• Pytorch 1.12.0
• Pytorch Geometric 2.1.0.post1

More information about required packages is listed in requirements.txt.

We provide the commands with hyper-parameters for all datasets in NODESAFE/run.sh. For example, for Cora with structure manipulation as OOD, one can run the following scripts for training and evaluation of baseline MSP and our models.
