Zhang, Yunyi (author), Shi, Zhan (author), Feng, Dan (author), Zhan, X. (author)Network embedding aims at learning node representation by preserving the network topology. Previous embedding methods do not scale for large real-world networks which usually contain millions of nodes. They generally adopt a one-size-fits-all strategy to collect information, resulting in a large amount of redundancy. In this paper, we propose...journal article 2019
