Hi! I'm Phi. I am a PhD candidate in Computer Science in Nanyang Technological University, Singapore (NTU). I work in Neural Natural Language Processing under Prof. Shafiq Joty. I focus in various aspects of Neural Machine Translation methods, especially unsupervised and semi-supervised machine translation.
In summer 2021 and 2022, I conducted two Research Internship programs at Facebook AI Research (FAIR) under the supervision of Dr. Hongyu Gong. My work there involves Text and Speech based Neural Machine Tranlation.
Find my CV here.
My research involves various topics of Deep Learning in Neural Machine Translation (NLP). I try to innovate and invent novel models and architectures, such as the Transformer, to improve the performance of data-driven machine translation systems. I also explore numerous techniques to enhance unsupervised and semi-supervised machine translation systems, such as using diversification methods. My work can meaningfully contribute to the development of commercial translation systems like Google Translate.
Plus, I also work on other research projects regarding semantic parsing, summarization, speech translation etc.
