About Me
Hi, I am Weikai (Vica) Yang (杨维铠), an Assistant Professor at the Data Science and Analytics Thrust (DSA), and jointly appointed at the Computational Media and Arts Thrust (CMA) in Information Hub, the Hong Kong University of Science and Technology (Guangzhou). I received my Ph.D. degree in Software Engineering from Tsinghua University in 2024, under the supervision of Prof. Shixia Liu.
My research primarily focuses on the intersections between visual analysis and machine learning. The goal is to help general users understand large-scale data and utilize machine learning models more effectively and efficiently by incorporating their knowledge and feedback. Specifically, my research directions include VIS4AI, AI4VIS, human-AI collaboration, intelligent data analysis, and active learning.
I am actively seeking self-motivated Ph.D. students and RAs (Click Here!). If you are interested in working with me, please send an email with your CV and transcripts for all degrees. You may consider taking a look at our spotlight paper Foundation Models Meet Visualizations: Challenges and Opportunities, which covers many future research directions I would like to explore.
