Shujian Yu (余书剑)

I am Shujian Yu, an assistant professor of machine learning in the Department of Artificial Intelligence at the Vrije Universiteit Amsterdam. I also hold a guest position in the Machine Learning Group at the UiT - The Arctic University of Norway. I graduated from the University of Florida in the Department of Electrical and Computer Engineering, working with Prof. Jose C. Principe, with a Ph.D. minor in theoretical statistics. Previously, I obtained my BEng degree from the School of Electronic Information and Communications at the Huazhong University of Science and Technology. I was a research scientist of machine learning at the NEC Laboratories Europe from 2019 to 2021.

I am doing research on the intersections between machine learning, information theory and signal processing, which include topics like information-theoretic learning and machine learning for signal processing. Particularly, I am interested in information-theoretic quantities (such as entropy, mutual information, divergence, etc.) estimation, improving the explainability and generalization of deep neural networks by information-theoretic principles (such as the information bottleneck and the principle of relevant information). I am also interested in brain data analysis (such as EEG and fMRI).

I am the recipient of the 2020 International Neural Networks Society Aharon Katzir Young Investigator Award. I am also selected for the 2023 AAAI New Faculty Highlights.
