Yuchen Xie

I am a third-year undergraduate student at Nanyang Technological University (NTU), Singapore. My research interests lie in Generative AI, with applications in world models and robotics. I am currently doing research on 3D/world models at the Spatial Intelligence Lab, advised by Prof. Jiawang Bian. I am also an algorithm engineer intern at ByteDance, working on AIGC.

Previously, I interned as a computer vision algorithm engineer at Whale Cloud. I am grateful to have worked closely with and received extensive help from Prof. Weisi Lin, Prof. Jianfei Yang, Dr. Donny Y. Chen, Dr. Xinyu Zhou, Weijie Wang, Xin Li and Annan Wang.

I'm always glad to talk about research or collaboration—just email me at XIEY0038@e.ntu.edu.sg.

USS method USS: Unifying Spatial-Semantic Prompting for End to End Embodied Visual Tracking
Yuchen Xie*, Xinyu Zhou*, Kuangji Zuo, Yanshuo Lu, Fengrui Huang, Boyu Ma, Jianfei Yang†
Paper / Project

USS lets a robot follow a target specified by text, a point, a box or a mask, mapping any of these prompts to egocentric waypoints end to end. Policies trained only in simulation transfer zero-shot to a real humanoid robot across 320 real-world trials.

DN-MOPD overview Beyond Teacher Assignment: Domain-Normalized Multi-Teacher On-Policy Distillation

Paper / Project

DN-MOPD keeps label routing in multi-teacher on-policy distillation but rescales each domain's teacher feedback by its measured spread, so that no single domain dominates the shared student.
