Hi! I am Letian (Zac) Chen, a first-year PhD student at Georgia Tech. I received my Bachelor’s degrees in psychology and computer science from Peking University in 2018 and a Master’s degree in computer science from Georgia Tech in 2020. Prior to joining the CORE Robotics lab, I was in CVDA (CS) and CDLab (Psy) at Peking University (Beijing, China). I love researching and implementing cool stuff that works on robots. I am interested in all kinds of intelligence problems, both artificial intelligence, and human intelligence. Specifically, I look into the intelligence problem through reinforcement learning perspective. My research enables robots to infer human’s intent in Learning from Demonstration settings, teasing out heterogeneity and suboptimality from the demonstrations. I envision human and machine share certain sources of intelligence, including but not limited to reinforcement learning (dopamine system), hierarchical learning (hippocampus), and meta learning (pre-frontal cortex), and I wish to reveal the mystery of intelligence through my work.
