Hi! I am a second-year PhD student at National Taiwan University (NTU) in Taipei, Taiwan. I am a member of Speech Processing and Machine Learning (SPML) Lab. I am advised by Prof. Hung-yi Lee.
My main research interest is natural language processing, especially self-supervised learning and pre-trained language models. I started my research from the BERT-era and I investigates why BERT works so well on downstream tasks. In the LLM-era, I still focus on pre-trained language models, including how to use those LLMs on diverse scenarios and how to augment LLMs with retrieval. I am also interested in the evaluation of diverse tasks and how to reliably assess an ML system.
