Biography

I am currently a tenure-track assistant professor in the State Key Lab of CAD & CG and a member of the GAPS Lab, Zhejiang University. I received Ph.D. degree in computer science from LAMDA, Nanjing University in 2020, advised by Prof. Zhi-Hua Zhou. Before that, I received M.Sc. degree in computer science from Peking University in 2014 and B.Sc. degree in mechanical engineering from University of Science and Technology Beijing in 2011.

Research Interests

I work on theories and algorithms of machine learning, with special interests on the following topics:

• active learning and machine teaching: understanding how prior information can help reduce the sample complexity.
• neurosymbolic generative learning: bridging symbolic (logical, causal) inference and neural network learning, with their applications in visual generation tasks.
• decision-making learning: imitation learning and model-based reinforcement learning.
• model reuse: reusing pre-trained models under decision-making and visual generation tasks.
