Graph-based Security and Privacy Analytics via Collective Classification with Joint Weight Learning and Propagation
Binghui Wang, Jinyuan Jia, Neil Zhenqiang Gong
Many security and privacy problems can be modeled as a graph classification problem, where nodes in the graph are classified by collective classification simultaneously. State-of-t…
SybilBlind: Detecting Fake Users in Online Social Networks without Manual Labels
Binghui Wang, Le Zhang, Neil Zhenqiang Gong
Detecting fake users (also called Sybils) in online social networks is a basic security research problem. State-of-the-art approaches rely on a large amount of manually labeled use…
SybilFuse: Combining Local Attributes with Global Structure to Perform Robust Sybil Detection
Peng Gao, Binghui Wang, Neil Zhenqiang Gong +3
Sybil attacks are becoming increasingly widespread and pose a significant threat to online social systems; a single adversary can inject multiple colluding identities in the system…
Structure-based Sybil Detection in Social Networks via Local Rule-based Propagation
Binghui Wang, Jinyuan Jia, Le Zhang +1
Sybil detection in social networks is a basic security research problem. Structure-based methods have been shown to be promising at detecting Sybils. Existing structure-based metho…
Stealing Hyperparameters in Machine Learning
Binghui Wang, Neil Zhenqiang Gong
Hyperparameters are critical in machine learning, as different hyperparameters often result in models with significantly different performance. Hyperparameters may be deemed confid…
Robust Multi-subspace Analysis Using Novel Column L0-norm Constrained Matrix Factorization
Binghui Wang, Chuang Lin
We study the underlying structure of data (approximately) generated from a union of independent subspaces. Traditional methods learn only one subspace, failing to discover the mult…
