I am an Assistant Professor of Computer Science in the School of Computing and Information Systems at Singapore Management University (SMU). Before coming to Singapore, I worked as a Guest/Postdoc Researcher with Prof. Luc Van Gool in Computer Vision Lab at ETH Zurich. My SAVG (SMU Autonomous Vision Group) researches autonomous visual computing that aims for making machines to learn the visual world, all by themselves. Our current research focuses on visual deepfake, affective and behavior computing through automated machine learning on data, label, feature, neuron and task. Our ultimate quest is artificial general intelligence with rational, emotional and imaginal capabilities.
I am looking for motivated and talented PhD students to join my research group. Please follow the instructions to reach me if you are interested.

09/2022, One paper "S-Prompts Learning with Pre-trained Transformers: An Occam's Razor for Domain Incremental Learning" gets accepted to NeurIPS 2022. This paper proposes a rule-breaking paradigm (S-Prompting) for domain incremental learning. It does not require the accumulation of the knowledge from previously learned domains. Instead, it merely learns the knowledge independently domain by domain, through simply prompting the state-of-the-art transformers.
