Hi! I am currently a postdoctoral research fellow at NExT++, School of Computing, National University of Singapore with Prof. Tat-Seng Chua.
2017 - 2021 I received Ph.D. from the ReLER Lab, University of Technology Sydney (UTS) , under the supervision of Prof. Yi Yang and Dr. Liang Zheng.
2012 - 2016 I received my Bachelor’s degree from Fudan University in 2016, under the supervision of Prof. Xiangyang Xue.
2018, 2020 I was fortunate to spend my summer working with Xiaodong Yang (Nvida), Zhiding Yu (Nvidia), Jan Kautz (Nvidia), Minyue Jiang (Baidu) and Xiao Tan (Baidu).
Open-source projects can be found at my [Github], and publications can be found at SCI, SCOPUS, or Google Scholar.
More details can be found in my [CV].
If you are a NUS Undergraduate / Master student who is interested in doing research/project with me, please contact me via email with your CV. My current email address is zdzheng AT nus.edu.sg .
My work focuses on image retrieval and image generation.
Big data is the primary part of training data-driven models. There remain three scientific questions.
Data Generation: How to obtain more data? Due to the annotation costs and privacy concerns, we usually could not access the large-scale data easily.
Prior Knowledge: Does more data mean a better model? Deep learning also demands a deep understanding of data (robustness and explainability).
Efficiency: How to train on million-scale data? What data matters most? Efficient training and inference is needed.
News We are holding the special session at ICME 2022 on Beyond Accuracy: Responsible, Responsive, and Robust Multimedia Retrieval. [Call for papers] My Ph.D. thesis was on the Chancellor's List. I was awarded 2021 IEEE Circuits and Systems Society Outstanding Young Author Award. Thanks a lot for supports and understanding from my supervisors and friends.

Others Shanghai is my hometown, and it is a lovely place to have a sightseeing tour. I was a poster maker when I studied at Fudan University. You may check out them at Here. I sometimes write Chinese blogs and share insights at Zhihu.
