Qi Fang(方淇)

I am a first-year CS Master student at University of Toronto.

My research interests are in Computer Vision, AI Security, and Robotics. Specifically, to make self-driving cars robust under the conditions of adverse weather and adversarial attacks.

I am also interested in LLM x Robotics, Embodied AI, HCI, and AI for Social Good.

I was fortunately in research collaboration at AI4CE LAB, New York University, supervised by Prof. Chen Feng and Dr. Felix Juefei Xu. Previously I interned at iDLAB, Tsinghua University, advised by Prof. Wenjun Wang, where I focused on human behavior interacting with self-driving vehicles.

Publications
Among Us: Adversarially Robust Collaborative Perception by Consensus
Yiming Li*, Qi Fang*, Jiamu Bai, Siheng Chen, Felix Juefei-Xu, Chen Feng
International Conference on Computer Vision (ICCV), 2023
arXiv / code

We proposed a novel probability-guaranteed sampling method inspired by RANSAC to achieve a trust-worthy group of benign agents, outperforming adversarial training Method by 73%.

Occ4cast: LiDAR-based 4D Occupancy Completion and Forecasting
Xinhao Liu*, Moonjun Gong*, Qi Fang, Haoyu Xie, Yiming Li, Hang Zhao, Chen Feng
arXiv, 2023
arXiv / project / code / data

We proposed a new LiDAR perception task, Occupancy Completion and Forecasting (OCF), combining scene completion and forecasting in autonomous driving, and evaluates it using the newly curated OCFBench dataset.

Influence of the Relative Position of Surrounding Traffic on Drivers’ Take-over Performance
Qingkun Li, Andrej Naumenko, Qi Fang, Ali Muhammad Hadi, Lian Hou, Wenjun Wang, Quan Yuan, Bo Cheng
International Conference on Applied Human Factors and Ergonomics (AHFE), 2021
Paper

We validated a key indicator of relative position between the ego vehicle and surrounding vehicles having important effects on take-over performance and driving safety.
