    Research Overview
    My research focus broadly on innovative use and design of machine learning algorithms and systems, especially on structured and multi-relational graph data. Several areas of recent work include:
  • Multimedia knowledge graph, vision and language.
  • Popularity in social media -- understanding, predicting, and optimization.
  • Machine learning and applications.
  • Details can be found from the sample projects below and the list of publications.
