I am a "Hundred Talent" Research Fellow in College of Computer Science and Technology, Zhejiang University. I have over 30 publications appeared in top conferences and journals such as AAAI, WWW, SIGIR, KDD, TOIS and CIKM. My research interests include information retrieval, data mining and machine learning, particularly in recommender systems, robustness, and graph neural network. Moreover, I have served as the PC member for top-tier conferences including AAAI, WWW, KDD, ACMMM and the invited reviewer for prestigious journals such as TNNLS, TKDE, TOIS.
Notes: 1. We recently release two surveys on recommendation biases and deep clustering:
- Bias and Debias in Recommender System: A Survey and Future Directions
- A comprehensive survey on deep clustering: Taxonomy, challenges, and future directions
- Conditional Image Synthesis with Diffusion Models: A Survey
- You may be interested in these emerging topics!
2. I'm looking for self-motivated master/PHD students. If you are interested in the recommender system, large language models, graph mining, diffusion model or robust machine learning, please send me your CV.
