Research Overview
My research focus broadly on innovative design and use of machine learning algorithms, especially on large-scale graph data and collective behaviour. Several areas of recent work include:
  • Popularity in social media -- understanding, predicting, and optimization.
  • Multimedia knowledge graphs, vision and language.
  • Humanising machine intelligence.
  • Details can be found from the sample projects below and the list of publications.
