Boqian is a first-year Ph.D. student at the University of Twente in the Data Management & Biometrics (DMB) group. During her Ph.D., she is focusing on sparse neural networks, specifically the theoretical aspects of such networks. Her goal is to uncover the mechanisms that underlie the practical effectiveness of sparse neural networks.

Dynamic sparse training algorithms have shown promise in achieving high performance while reducing resource costs, making them an attractive option in machine learning. However, despite their potential, the theoretical properties of dynamic sparse training remain largely unexplored. My research aims to fill this knowledge gap by investigating the theoretical properties of sparse training models. As a result, guidelines will be developed for applying dynamic sparse training to real-world problems.
