Jianan Li

Hi, welcome to my personal page. I am currently a 4th-year PhD stduent at the State Key Laboratory of Multimodal Artificial Intelligence Systems (MAIS), Institute of Automation, Chinese Academy of Sciences, advised by Prof. Qiulei Dong. I obtained my B.Eng. degree from Sun Yat-sen University (SYSU) in 2021.

My current research interests generally foucs on:

3D Point Cloud Semantic Segmentation;
Open-set Learning;
Semi-supervised Learning;
Multi-modal Large Language Models.
