Job description

The Faculty of Science and the Leiden Institute of Advanced Computer Science (LIACS) are looking for:

PhD Candidate, Detailed Video Understanding
Thanks to revolutions in supervised learning, the emergence of large, labelled video datasets and a research focus on what is happening, tremendous progress has been made in video understanding. However, current algorithms cannot identify how actions happen, which is key to achieving the desired outcome. The major research challenge is to recognize such details while not having examples of every situation they could occur in.
Applications are invited for two fully funded PhD studentships in Computer Vision and Machine

Learning on the topic of Detailed Video Understanding. The aim is to go beyond the coarse-grained labels that current models can predict and design models that can acquire a deeper understanding of video while learning from limited supervision. For insight into the supervisor’s current and previous works please refer to:
Hazel Doughty:

Key responsibilities
  • Conduct original and novel research in the field of Computer Vision, focusing on Video Understanding;
  • Design and implement new deep-learning algorithms to learn from video data;
  • Publish and present scientific articles at international journals and conferences;
