I am Hongbang Yuan, a master student at the Laboratory of Language and Knowledge Computing, Institute of Automation, Chinese Academy of Sciences, advised by Prof. Yubo Chen and Prof. Jun Zhao. My research interests lie in natural language processing, particularly in the hallucination, factuality, and trustworthiness of large language models.
