My Positions and Research

  • Full Professor, Hoogleraar Deep Learning at LIACS, Leiden University

  • Co-head of the LIACS Computer Systems, Imagery and Media Research cluster (30+ members), which is one of the two main research groups at the computer science department at Leiden University.

  • Chair Full Professor at Tsinghua University (US News Ranking for Computer Science | Ranking Eng. | Archive | in China | ARWU | ARWU-CS), 2003- (month-long visits)

    Research - short version

    My research lies in the field of artificial intelligence and the sub-fields of deep learning and computer vision. I develop new deep learning algorithms for automatic image understanding and exploiting synergy between the user and the computer in novel interactive and intelligent search paradigms.

    Research - longer version

    My research lies in the field of artificial intelligence and the sub-fields of deep learning and computer vision. My goal is to endow computers with all of the capabilities of the human visual system. The most promising approach is the paradigm of deep learning which involves developing and training deep convolutional neural networks for each visual task using large training sets. The deep learning and computer vision algorithms I develop are typically used for solving problems in the area of multimedia retrieval which covers the fundamentals (theory and practice) of searching for visual/image information along with additional media such as text and audio (multimedia) where the primary hurdle is the semantic gap. Multimedia retrieval provides the urgency in both societal and scientific challenges. It also ensures that humans are always in the loop because humans create the queries for information.

    Because humans want to express their search queries using high level human concepts, the grand challenge in multimedia retrieval has been "bridging" the semantic gap which is the gap between the high level concepts of humans and the low level features from images. The problem of image classification is especially important because it can bridge the semantic gap by taking an input image and outputting human level concepts. If we can solve the semantic gap, then it would make all of the collected art/heritage, scientific, WWW and personal images searchable and accessible.
