Shengjie Kris Liu
Profile
Shengjie Liu’s research uses advanced statistical and machine learning methods (or AI in laymen’s terms) to analyze earth observation data (AI4EO), with topics covering few-shot learning, multitask learning, and open-set recognition. In one of his representative works, collaborated with Dr. Qian Shi and IEEE Fellow Dr. Liangpei Zhang, he proposed multitask deep learning for open-world classification (MDL4OW), which is among the first to tackle unknown classes in hyperspectral image classification. This work has received more than 150 citations in three years and...
