My current research interest lies in using computational methods to study mechanisms, to address some social dilemma issues in game theory, in which scenarios everyone being self-interested may lead to the detriment of social welfare. [Click here to see details of my research interests]
- The method I use is Multi-Agent Reinforcement Learning (MARL), essentially with the rationality assumption. And I have recently started working with some tools that seem more "human-like", like large language models.
- Specifically I am focusing on the problem of Bayesian persuasion (BP, [my blog]) in economics: a sender with an informational advantage tries to persuade a receiver, who has different motives, to take actions that are beneficial to the sender. My research is on sequential decision-making situations.
- A representative work on this is this [my blog] (NeurIPS), where we proposed a general model-free RL algorithm for multi-agent communication (for the cognoscenti: policy gradient for communication), and expanded the constraints in BP so that mixed-motive communication (even between two agents) in MARL is conceivable.
- During my undergraduate years (specifically, from 2019 to 2021), I dabbled in robotics, understood kinematics, and played a bit with dynamics [my repo].
- I presented a purely simulation-based robotic mechanism design work [my blog] at ICRA. It is about a hybrid leg can transform into various forms (wheel, legs, RHex) to adapt to different terrains, and can even climb ladders.
- Also I have implemented [my blog] a "gimbal" using a hyper-redundant manipulator (purely based on kinematics), allowing it to efficiently reach into barrels.
And how could one endure being a man, if not also for the possibility to create, guess riddles, and redeem accidents? To redeem those who lived in the past and to recreate all "it was" into "thus I willed it" — that alone should I call redemption. — Friedrich Nietzsche, Thus Spoke Zarathustra.
