Justin Chih-Yao Chen
CS Ph.D. Student @ UNC Chapel Hill

I am a first-year Ph.D. student at The University of North Carolina at Chapel Hill, advised by Prof. Mohit Bansal. Prior to that, I earned my master’s degree from the Data Science Program at National Taiwan University, advised by Dr. Lun-Wei Ku and Prof. Hsin-Hsi Chen. My research interests lie generally in Natural Language Processing, LLM Reasoning, Representation Learning and Knowledge Graph.
When I was an undergraduate, I double majored in Computer Science and Statistics at National Cheng Kung University. I had the pleasure of working close with Prof. Cheng-Te Li, on topics related to Relation Extraction and Recommendation System.

ReConcile: Multi-Round Discussion Among Diverse LLMs
Improve LLM reasoning via multi-round discussions.
Enhanced NLI-based Fact-Checking System
Prevent the NLI model from learning short cuts by using HEX projection.
Fine-grained Emotion Classification (FEC)
Incorporate hyperbolic space and Parrott's emotion model from psychology.Education
