Yichen Jiang (姜翌辰）

I'm a 5th(final)-year PhD student at Department of Computer Science at University of North Carolina at Chapel Hill. I am advised by Prof. Mohit Bansal and work in UNC-NLP Research Group. My research focuses on analyzing and improving neural networks' ability to understand the compositional structures underlying natural language, as well as interpretability and adversarial robustness of multi-hop reasoning. In the past, I did my BS + MS at UNC Chapel Hill and interned at Microsoft Research and Facebook AI. I'm supported by the Apple Scholars in AI/ML PhD fellowship.

Research

My research focuses on analyzing and improving the neural network’s ability to understand the compositional structures underlying natural language sentences. In the past, I showed how existing models lack compositionality and take reasoning shortcuts. I then designed interpretable and modular models that can answer complex multi-hop questions more robustly and also collected a multi-hop fact verification dataset HoVer to motivate future work. I also incorporated Tensor-Product into a Transformer for better abstractive summarization. My ultimate goal is to build AI systems that can compositionally recombine structures and contents in understanding natural language and comprehending this world.
