Weixiang Zhao 赵伟翔

Hello, I am a Ph.D. student at the Research Center for Social Computing and Information Retrieval (SCIR) at Harbin Institute of Technology (HIT), China. I am advised by Prof. Yanyan Zhao and Prof. Bing Qin. And I also collaborate closely with Prof. Wanxiang Che. My research focuses on emotional dialogue systems, sentiment analysis, continual learning, and the alignment of large language models.
