LINKExtension

LINKExtension

This repository provides a reference implementation for "Node Attribute Prediction on Multilayer Networks with Weighted and Directed Edges" on the protein-protein network from <a href="https://ogb.stanford.edu/">Open Graph Benchmark</a>.

Documentation

This repository contains code to replicate the results in the paper on the protein-protein network from the Open Graph Benchmark repository. All code was run in March/April 2023. We do not include data for replicating internal FB results but note that the code architecture is the same as the simulation.

Directions

This repository illustrates how to run the LINK extensions on a publicly available dataset. All code was run with Python 3.8.6. Since we report ROC-AUC metrics, we do not normalize degree counts as illustrated in the paper. If you report other predictive performance metrics, you will want to add this normalization back-in. For this paper, we also enfoce bins with no edges to be 0.

Single-Layer

• All notebooks are run from the /single_layer/ folder
• Update all file paths for saving output
• Code is run in parts which correspond to the different outcomes, so comment out related section

Multi-Layer

• All notebooks are run from the /multi_layer/ folder
• Update all file paths for saving output
• Code is run in parts which correspond to the different outcomes, so comment out related section
