About Me

Hi, I am Weikai (Vica) Yang (杨维铠), a 4th-year Ph.D. student in Software Engineering, Tsinghua University, advised by Prof. Shixia Liu. Prior to that, I was an undergraduate student at Tsinghua University, where I majored in Software Engineering(2015-2019) and minored in Statistics(2017-2019).
My research interests lie in integrating Machine Learning into Visual Analytics, which can facilitate the understanding of large-scale data and make it easier for practitioners to use machine learning techniques.

Miscellaneous

• I participated in the development of Human’: Ethical Reflection on Future Cyberworld Identity, a work of art that disucsses the cyberworld and our identity.
• I enjoyed sprint (12.11s/100m, 25.39s/200m). However, it is not enough to get a medal in Ma Yuehan’s Cup, which is one of my regrets.
• I have been a volunteer for Drop-in Tutoring for STEM Courses in Tsinghua University since 2015. I also made a lot of friends through this programs.
