Biography
I'm currently a second-year PhD student in The University of Hong Kong, supervised by Prof. Liangqiong Qu.
I received my Master degree in Southern University of Science and Technology under the supervision of Prof. Yu Zhang in 2023, and the B.Eng degree in Northeast Forestry University in 2020.
I am interested in the foundation of machine learning including multi-task learning, transfer learning, and federated learning and their industrial applications.
