Yongjie Wang王永杰

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,

I am open and welcome to collaborate with researchers, who have similar interests in XAI. Feel free to drop me an email.
