Neural-Brane: Neural Bayesian Personalized Ranking for Attributed Network Embedding

1 code implementation23 Apr 2018 Vachik S. Dave, Baichuan Zhang, Pin-Yu Chen, Mohammad Al Hasan

For a given network, Neural-Brane extracts latent feature representation of its vertices using a designed neural network model that unifies network topological information and nodal attributes; Besides, it utilizes Bayesian personalized ranking objective, which exploits the proximity ordering between a similar node-pair and a dissimilar node-pair.
