Yen-Cheng Liu

I am a 3rd year PhD student at Georgia Tech and work with Prof. Zsolt Kira. My research interests are in the areas of computer vision and machine learning, particularly learning with limited supervision, scene understanding, domain adaptation, and representation learning. I've been lucky to be a Research Intern at Facebook Research during summer 2020 and summer 2021. Previously, I was a research assistant and worked with Prof. Yu-Chiang Frank Wang at National Taiwan University.

Side Projects

Jenga Builder

Collaborator: Kilian Contamain, Edwinn Gamborino, Da-Wei Liu
The proposed system aim at rebuilding a Jenga® tower from a randomly positioned and relatively large set of pieces in a surface using only one RGB camera and a 6-DOF robotic manipulator
