Yinqiong Cai (蔡银琼)
I am now a Senior R&D Engineer at Baidu Search. Before that, I received the Ph.D. degree in Computer Science at Institute of Computing Technology, Chinese Academy of Sciences, advised by Prof. Jiafeng Guo. My research interests lie in Information Retrieval, with a special focus on dense retrieval. Recently, my research focuses on the integration of large language models and information retrieval.
Prior to this, I earned my Bachelor’s degree at School of Software Technology, Dalian University of Technology, advised by Prof. Xiangjie Kong. My research interests include big data, mobile computing, and computational social science.
