Who am I?
Hi there! I am Kai Yan (颜开 in Chinese), a second-year Ph.D. student in the Department of Computer Science at University of Illinois Urbana-Champaign (UIUC), co-advised by Prof. Alexander Schwing and Prof. Yu-Xiong Wang. Prior to that, I get my Bachelor of Science degree in computer science at Peking University with a Summa Cum Laude and a national scholarship. In my high school years, I learned informatics and got a silver award in the National Olympiad of Informatics (NOI 2016).
My research interest is deep learning for better decision making, which is mainly deep reinforcement learning and imitation learning. I have conducted research in the following fields: 1) optimization with prediction, 2) multi-agent reinforcement learning, 3) demonstration-guided reinforcement learning and imitation learning, 4) decision transformer, and 5) Large Language Model (LLM)+MCTS.

Working Experiences
I worked in Microsoft Research Asia mentored by Dr. Jie Yan and Chuan Luo from Sept. 2020 to Jun. 2021, and was awarded Stars of Tomorrow.
Teaching Experiences
I was a teaching assistant for Introduction to Computer Systems (Fall 2019) at Peking University, where I led a seminar of 15 people every week, revising and expaning lessons taught in class, grading homeworks, and teaching how to write lecture notes.

Other Experiences
I served for the department of outreach in the EECS Student Union of Peking University in 2017-2018, and as the vice president of the EECS Student Union in the academic year of 2018-2019. We have organized awesome events with hundreds of participants, such as Hackathon and Freshmen Ball.

Hey, you find my easter egg! I am a lover of strategic PC games, such as Frostpunk, Civilization, Stellaris, Hearts of Iron, Victoria and Total Wars. That’s also something where you need to make good decisions :)
