THU Internship


I'm currently interning in Dr. LI Guoliang's Lab in Tsinghua University Beijing during this summer.

We are designing a new approach to deal with lage scale trajectory data. How to efficiently analyze the trajectories is crutial to many real-time applications.

Social Works


For the good of the community, I have been volunteering in many activities, such as Non-Ethnic Chinese (Western District) Program, SERVICE 100 Mooncake Project, stray animal protection, and environmental protection.

Also, I have been served as the RPG Student Representative of the Department of Computer Science in the University of Hong Kong during the last academic year, and the PG representative of Starr Hall in the HKU Inter-hall Academic Symposium and Competition 2017.

HIT Winter Camp


The HIT campus in Harbin is smaller compared to the campus in Shenzhen and Weihai, but it is much cooler! Happy Winter Camp in Frozen City 2016.

HKU Internship


During my internship, I have developed a novel algorithm that enables search of a community (e.g., hobbyists in photography) within a large social network. We have also performed experiments on real datasets to verify the correctness and efficiency of this algorithm.

SDU RA Experience


We have analyzed the semantics of tags on resources (e.g., URLs) in the Delicious website, and then cluster the users of similar behaviors. A heuristic recursive binary partitioning algorithm is designed.

Finally, to achieve privacy preserving, some tags are filtered out with minimum precision loss.

National Innovative Training Projects


We designed an Electronic-Visual (E-V) system to identify object's appearance model and accurate localization from large volumes of video data with the help of mobile phone signals.

We designed electronic and visual signals processing algorithm.

Then electronic frame filtering and E-V mapping are achieved.

Android apps were developed to achieve better distance calculation.

NTHU Exchange


We built a software-based GPU virtualization environments by KVM on CentOS.

Then we achieved NVidia Quadro6000 pass-through and GPU forwarding.

We also built Spice desktop virtualization to test the scheduling algorithm designed by us.
