Unsupervised Network Embedding Beyond Homophily

(also named as: Unsupervised Heterophilous Network Embedding via r-Ego Network Discrimination)

Implementation of Selene with Pytorch.

Required packages

The code has been tested running under Python 3.9.6. with the following packages installed (along with their dependencies):

• numpy == 1.16.5
• pandas == 0.25.1
• scikit-learn == 0.21.2
• networkx == 2.3
• pytorch == 1.9.0
• torch_geometric == 2.0.1
• gensim==3.6.0
• fastdtw==0.3.2
• lightning-bolts==0.4.0

Data requirement

All eight datasets we used in the paper are all public datasets which can be downloaded from the internet.
