I am a fourth-year PhD student majoring in Statistics at the University of Wisconsin-Madison. My previous research experience has been primarily centered around machine learning, with a particular focus on the processing of sequential data. Currently, I am pursuing research interests in social network analysis, non-Euclidean models and large language models (LLM). I am privileged to work under the guidance of Professor Karl Rohe and Professor Frederic Sala.
Prior to that, I graduated from Zhejiang University with a B.S. in Statistics and the University of Wisconsin-Madison with a M.S. in Statistics. During my master's studies, I was lucky to work with Dr.Sebastian Raschka and co-authored Chapter 16: Transformers–Improving Natural Language Processing with Attention Mechanisms in his book Machine Learning with PyTorch and Scikit-Learn.
