Zhiqiang finished his first project in January 2019, which used a graph-based method to understand the relation between hashtags and image contents in online social networks.
He focuses on social network analysis and its related machine learning technologies, like Graph Neural Networks, in particular on social network related security and privacy issues. This means integrating machine learning and information security technologies to study the security and privacy issues in social networks including link prediction and attribute inference.
Zhiqiang’s goals for this PhD is to make my contributions in security and privacy research of social networks and the security of graph neural networks.
