Jung-Chun Liu

I am a research assistant with Professor Shao-Hua Sun at NTU Robot Learning Lab. Previously, I received my M.S. degree from National Taiwan University, where I was advised by Professor Tian-Li Yu at Taiwan Evolutionary Intelligence Laboratory. I received my B.S. degree with double majors in Electrical Engineering and Psychology from National Taiwan University in 2021.

Research

I have always been interested in understanding intelligence in both humans and machines. Particularly, my curiosity centers on learning, reasoning, decision-making, and the cognitive architecture that articulates these abilities. My previous work resides at the nexus of computer science and cognitive science, covering areas such as reinforcement learning, symbolic AI, collective behavior models and workload assessment. Representative papers are highlighted.

	Integrating Planning and Deep Reinforcement Learning via Automatic Induction of Task Substructures Jung-Chun Liu, Chi-Hsien Chang, Shao-Hua Sun, Tian-Li Yu NeurIPS Workshop on Generalization in Planning, 2023 International Conference on Learning Representations (ICLR), 2024 We propose a framework that integrates DRL with classical planning by automatically inducing task structures and substructures from a few demonstrations. We adopt genetic programming where the program model reflects prior domain knowledge of effect rules.
	GP with Ranging-Binding Technique for Symbolic Regression Wen-Zhong Fang, Chi-Hsien Chang, Jung-Chun Liu, Tian-Li Yu Proceedings of the Companion Conference on Genetic and Evolutionary Computation (GECCO), 2023 This paper proposes a model-based genetic programming algorithm for symbolic regression, called the ranging-binding genetic programming algorithm (RBGP).

	Multi-Robot Formation Control using Collective Behavior Model and Reinforcement Learning Jung-Chun Liu, Tsung-Te Liu IEEE International Symposium on Circuits and Systems (ISCAS), 2022 This paper presents an approach that combines swarm intelligence and reinforcement learning to realize accurate and reliable operations. An area-energy-efficient hardware architecture is proposed to perform formation control in a distributed robotic system. Bibtex / website / pdf
	Assessing Perceptual Load and Cognitive Load by Fixation-Related Information of Eye Movements Jung-Chun Liu, Kuei-An Li, Su-Ling Yeh, Shao-Yi Chien Sensors, 2022 We aimed to resolve the discrepancy of previous results by differentiating two kinds of mental workload (perceptual load and cognitive load) and manipulated them independently using a modified video game. We found opposite effects of the two kinds of mental workload on fixation-related parameters. Bibtex / website / pdf
