Qinjie Lin

I am currently a fourth-year Phd student in the Computer Science Department at Northwestern University, advised by Prof. Han Liu.

I received my Bachelor's Degree in 2018 at South China University of Technology, where I was advised by Prof. Sheng Bi.

I completed an AI Research Scientist internship at Meta Reality Lab and a Machine Learning Engineer Internship at Zebra Tech.

Switch trajectory transformer with distributional value approximation for multi-task reinforcement learning
Qinjie Lin, Han Liu, Biswa Sengupta
Submission to ICML, 2023
paper

We propose SwitchTT, a multi-task extension to Trajectory Transformer but enhanced with two striking features: (i) exploiting a sparsely activated model to reduce computation cost in multi-task offline model learning and (ii) adopting a distributional trajectory value estimator that improves policy performance, especially in sparse reward settings.

Working on submission
github

We develop a JAX-Based body dynamics algorithm library for rigid body dynamics. This library contains a highly efficient python library that contains some essential rigid body dynamics algorithms.

Collision-free Navigation of Human-centered Robots via Markov Games
Guo Ye*, Qinjie Lin*, Tzung-Han Juang, Han Liu,
ICRA, 2020
paper / video/ code

Collision-free navigation for human-centered robots is interesting and we exploit adversarial learning to learn robot collision avoidance policy.

Learning to Plan in High Dimensions via Neural Exploration-Exploitation Trees
Binghong Chen, Bo Dai, Qinjie Lin, Guo Ye, Han Liu, Le Song,
ICLR, 2020
arXiv/ video/ code

Path planning in high dimension is pretty tricky but we propose a meta path planning algorithm to solve planing problems.
