AAANE: Attention-based Adversarial Autoencoder for Multi-scale Network Embedding

no code implementations24 Mar 2018 Lei Sang, Min Xu, Shengsheng Qian, Xindong Wu

Existing methods usually adopt a "one-size-fits-all" approach when concerning multi-scale structure information, such as first- and second-order proximity of nodes, ignoring the fact that different scales play different roles in the embedding learning.
