Biography
I passed my oral defense in July 2023. I am now a research staff at School of Computer Science and Engineering at Nanyang Technological University, under supervision of Professor Miao Chunyan. Before that,
I received Bachelor degree from college of software, Jilin university, and Master degree from Institute of computing technology, Chinese Academy of Sciences,
advised by Professor Zhang Yongdong and Associate Professor Gao Ke.
My research interests include explainable artificial intelligence (XAI) (Git Repo) on healthcare and medical image computing. Recently, I am working on counterfactual explanations and feature attribution problems, which contain sub-problems as follows,
Exploring philosophy of counterfactual explanations from multiple disciplinaries, e.g., causality, psychology and social science.
Generating actionable and feasible counterfactual explanations for specific requirements or under more challenging settings.
Leveraging counterfactual explanations into learning paradigm.
Overcoming weakness of existing counterfactual explanations, e.g., robustness, efficiency and security issues.
Feature attribution, i.e., generating explanable and faithful explanations.
Concept-level explanation, i.e., understanding the high-level representation in a DNN.
I am open and welcome to collaborate with researchers, who have similar interests in XAI. Feel free to drop me an email.
