Rui Dai

I am a Ph.D. student in Computer Vision (CV) and Artificial Intelligence (AI) at the Inria under the supervision of Prof. Francois Bremond. I also have a close collabration with Toyota Motor Europe (TME). Rui Dai's research interests include human action understanding, scene understanding and transfer learning.

I received the Master and Engineer degree in Electronics from Toulouse University. I obtained his Bachelor degree in Computer Science from Beihang University (BUAA) in Beijing, China.

Research

I'm interested in deep learning methods for computer vision problems such as activity understanding and holistic scene understanding. My research goal is to comprehend how spatio-temporal scene context can help in better understanding of action dynamics. I am also curious about complex interplay and mutual learning of tasks related to different modalities.
