I am a Ph.D. student at the University of Warwick (2020-) with Prof. Yulan HeLink opens in a new window doing Natural Language Processing, with special focus on sentiment analysis and interpretable NLP models. I finished my MSc. at Peking UniversityLink opens in a new window (2017-2020) with Prof. Chengqi Cheng doing spatial data mining and my BEng. at Beihang UniversityLink opens in a new window (2013-2017).
I pursue the fundamental principles of information bottleneck in large-pretrained model, with a particular focus on the expressivity of the self-attention mechanism. I derive probabilistic models guided by Bayesian perspectives, equipped with modern neural architectures to understand the latent features in sentiment analysis. I am also interested in leveraging the explanations to improve the current NLP models.
