Hi~ I am Tianyu Gao, a first-year PhD student at Princeton University, advised by Prof. Danqi Chen. Before joining Princeton, I received my bachelor degree at Tsinghua University. During my time at Tsinghua, I was a member of THUNLP and was advised by Prof. Zhiyuan Liu. Here is my CV.

Research


My research interests lie within the intersection of natural language processing and machine learning. More specifically, my research interests include:

  • Training NLP models with fewer annotations. Annotations for language are expensive to gather, so it is meaningful to develop models and algorithms that learn more efficiently.
    • Human can grasp new knowledge with only a handful of examples. So can machines. Few-shot learning aims at guiding models to learn new tasks with limited data.
    • There are huge amounts of unlabeled data on the Internet and we can utilize them with unsupervised / semi-supervised training, like pretraining language models or bootstrapping from a few seeds of annotations.
    • Existing structured information can act as an external knowledge for NLP models, like knowledge graphs in distant supervision relation extraction.
    • I explore the above aspects mainly in the field of information extraction, an important area in NLP.
