Jianxin Ma is pursuing a master’s degree in Computer Science and Technology at Tsinghua University, where he obtained a bachelor’s degree in Computer Science and Technology in 2017.
He conducts research under the supervision of Professor Wenwu Zhu and Peng Cui.
His research interests are mainly in machine learning, in particular representation learning, on relational data such as graphs, which has broad applications, ranging from social network analysis to recommender systems.
In particular, he strives to unify probabilistic generative modeling and deep representation learning, so as to accurately reveal the highly complex generating processes behind graph data and subsequently improve the robustness and interpretability of machine learning algorithms for graphs.
