Biography

Dawei Cheng is currently an assistant professor appointed at Department of Computer Science and Technology in Tongji University, Shanghai, China. I specialize in data mining, machine learning, deep learning and reinforcement learning. Now I mainly focus on deep learning in compext financial networks and other big data applications.

Prior to now, I was a postdoctoral associate at Center for Brain-like Computing and Machine Intelligence (BCMI), Shanghai Jiao Tong University (SJTU) , China. Before that, I obtained my Ph.D degree in computer science from Shanghai Jiao Tong University, supervised by Prof. Liqing Zhang and bachelor degree from Nanjing University of Aeronautics and Astronautics in China.
