I am Xiangtai Li, I work on computer vision, multi-modal learning and related problems.
I am working as a Research Scientist in Bytedance (Tiktok), Singapore.
Previously, I worked as a Research Fellow at MMLab@NTU, S-Lab advised by Prof.Chen Change Loy.
I obtained my PhD degree at Peking University (PKU) under the supervision of Prof.Yunhai Tong, and my bachelorโs degree at Beijing University of Posts and Telecommunications (BUPT).
Previously, I worked as research intern or research scientist in DeepMotion (Now Xiaomi Car) / JD Exploration Academy / Sensetime Research / Shanghai AI Laboratory / Skywork 2050 Research, with several research outputs on top conference and journals.
My research topics are:
Large Language Models (LLM) and Auto-regressive model.
Multi-modal learning with LLMs (MLLM): Benchmarking, New Architecture Design, Unified Modeling.
Diffusion Models, Image/Video Generation, Editing and Synthesis.
Previously, I did some works on image/video segmentation and detection, open vocabulary learning.
Moreover, the code and models for my works (maybe 98%), including the ones I have deeply contributed to, are open-sourced on GitHub.
I serve as a regular reviewer for CVPR, ICCV, ECCV, ICLR, AAAI, NeurIPS, ICML, IJCAI, IEEE-TIP, IEEE-TPAMI, IJCV, IEEE-TSCVT, IEEE-TMM.
