About Me

I received my PhD in June 2023 and am currently a Special Research Assistant (postdoctoral fellow) working in the Computer Network Information Center, Chinese Academy of Sciences, mentored by Prof. Yuanchun Zhou. I have published several papers prolifically on top-tier venues such as IEEE TKDE, ACM TKDD, AIJ, NeurIPS, IJCAI, IEEE ICDM, etc. I also serve as a PC member or reviewer on many premier international conferences and journals. My research topics include Data-centric AI, AI4LifeScience, and Scientific Data Mining. I have been honored with the Special Prize of the Chinese Academy of Sciences President Scholarship in 2023. 

I want to thank my classmates and friends such as Wang Dongjie (KU), Qiao Ziyue (GBU), and Ning Zhiyuan (CNIC, CAS), as well as my instructors or collaborators such as Zhou Yuanchun (CNIC, CAS), Fu Yanjie (ASU), Wu Min (A*STAR), Du Yi (CNIC, CAS), Wang Pengyang (UM), and Liu Kunpeng (PSU) for their support. Thank you for helping me get through the long night.

2023-08-04 : Data-Centric AI: Refining Representation Space from Decision-Making to Sequential-Generation Perspectives

In the realm of artificial intelligence, the quest for optimal representation space has been a critical pursuit, as it directly impacts the performance of various learning tasks. In this presentation, we delve into the concept of data-centric AI and explore two distinct approaches to refine the feature space: feature selection learning and feature generation learning. Approaching this study from two fundamental perspectives – the decision-making and sequential generation perspectives – we aim to shed light on the efficacy of each technique in enhancing the representation space. Through extensive evaluation of experimental results, it becomes evident that both feature selection learning and feature generation learning exhibit promising capabilities in shaping the representation space. This transformative capacity directly influences the performance of AI models, ultimately leading to superior results in various applications. By addressing the core tenets of data-centric AI, this research strives to highlight the crucial role played by feature selection and feature generation learning in refining the representation space. Armed with this knowledge, researchers and practitioners can make informed decisions when choosing the most suitable technique for specific AI tasks, ultimately advancing the field of artificial intelligence and its practical applications.

Dongjie Wang is currently pursuing his Ph.D. in the Department of Computer Science at the University of Central Florida. His primary research interests lie in the fields of data mining and machine learning, with a specific focus on automated data science systems, applied to large‐scale data problems, such as smart cities, anomaly detection, root cause analysis, automated urban planning, and user behavior analysis. He has published over 25+ papers in top‐tier data mining and artificial intelligence conferences and journals, such as TKDE, SIGKDD, AAAI, and KAIS. His research has been recognized with Best Paper Runner‐up Awards from SIGSPATIAL 2020 and ICDM 2021, respectively.
