Short Bio

Hello! I am Zicheng Zhao (赵子成), a PhD student of computer science at Nanjing University of Science and Technology advised by Prof. Chen Gong, and Prof. Shirui Pan. My research interests mainly focus on the areas of artificial intelligence and data mining, especially for the knowledge graph, large language model, and graph neural network.
