Attacking Fake News Detectors via Manipulating News Social Engagement
Haoran Wang, Yingtong Dou, Canyu Chen +3
Social media is one of the main sources for news consumption, especially among the younger generation. With the increasing popularity of news consumption on various social media pl…
Scalable Adversarial Attack Algorithms on Influence Maximization
Lichao Sun, Xiaobin Rui, Wei Chen
In this paper, we study the adversarial attacks on influence maximization under dynamic influence propagation models in social networks. In particular, given a known seed set S, th…
Influence Maximization with Spontaneous User Adoption
Lichao Sun, Albert Chen, Philip S. Yu +1
We incorporate self activation into influence propagation and propose the self-activation independent cascade (SAIC) model: nodes may be self activated besides being selected as se…
Unsupervised Meta-path Reduction on Heterogeneous Information Networks
Xiaokai Wei, Zhiwei Liu, Lichao Sun +1
Heterogeneous Information Network (HIN) has attracted much attention due to its wide applicability in a variety of data mining tasks, especially for tasks with multi-typed objects.…
Joint Embedding of Meta-Path and Meta-Graph for Heterogeneous Information Networks
Lichao Sun, Lifang He, Zhipeng Huang +4
Meta-graph is currently the most powerful tool for similarity search on heterogeneous information networks,where a meta-graph is a composition of meta-paths that captures the compl…
Multi-Round Influence Maximization
Lichao Sun, Weiran Huang, Philip S. Yu +1
In this paper, we study the Multi-Round Influence Maximization (MRIM) problem, where influence propagates in multiple rounds independently from possibly different seed sets, and th…
