About Me

Xiaobo Xia is currently a postdoctoral fellow at National University of Singapore, advised by Prof. Tat-Seng Chua. His research area is data-centric AI. The main research interests include trustworthy AI and AI for science. He serves as the area chair of NeurIPS, ICML, ICLR, and ACM MM.

PS: I will join in University of Sicence and Technology of China (USTC) as a Professor and PhD supervisor at Feb 2026. I am actively looking for self-motivated Ph.D/M.S./Undergraduate students in the areas of multimodal learning under resource constraints (e.g., computation, data, and knowledge resources) and world models. If you are interested, please feel free to send your CV to xbx@nus.edu.sg.

Research Interests

My general research interests lie in data-centric AI, with a particular emphasis on the following topics:

Trustworthy AI:
- Learning with noisy labels (multi-class) [NeurIPS'19, NeurIPS'20, ICLR'21, ICML'21, ICLR'22, CVPR'22, TPAMI'23, ICLR'23, ICCV'23, TPAMI'24]
- Learning with noisy labels (multi-label) [NeurIPS'22, ICCV'23]
- Out-of-distribution detection/generalization [NeurIPS'22, ICLR'23, CVPR'23, NeurIPS'23]
- Learning from crowds [TPAMI’24]
- Generalization for sparse data [KDD'22, NeurIPS'22]
- Coreset selection [ICLR'23, ICLR'24, ICML'24]
AI for Science:
- AI for environmental science [Nexus’25]
- AI for neuroscience
