I have received my Ph.D. degree in Shandong University in June 2024, supervised by Prof. Lei Meng. My research interests span cross-domain recommendation, diffusion-enhanced recommendation and multi-modal event forecasting. I have more than 10 publications appeared in several top conferences such as AAAI, IJCAI, MM, Recsys, ICMR, IJCNN, and journals including TOIS, JBI, CVMJ and Journal of Software. Moreover, I have been invited as the TPC/PC member for AAAI, IJCAI, ACMMM and Recsys and the Session Chair for IJCAI and IJCNN. I have just received the funding from the China Scholarship Council (CSC) and I will serve as the postdoc research fellow in NExT++ Research Center in Nov. 2024.
We have released a survey on the negative sampling strategies of Recsys:
