Personal profile

Biography

Dr Lan Du is a Teaching and Research Academic in the Faculty of IT, Monash Clayton Campus. He is particularly interested in statistical modelling and learning for text analysis, which broadly covers statistical machine leaning, natural language processing, data mining, and social network analysis.

Some specific research topics that he is interested in and currently working on:

  • Probabilistic topic modelling: He is extremely interested in developing various topic models that can explore different discourse structures and other meta information associated with natural lanugage text.
  • Nonparametric Bayesian methods, e.g., Dirichlet process, Pitman-Yor process, and Indian Buffet process. He has been working on developing different sampling methods for Pitman-Yor process since his PhD study at ANU.
  • Inference/optimisation algorithms, e.g., MCMC methods, Variational Bayesian (VB), and various numerical optimisation algorithms
  • Relational learning techniques, e.g., probabilistic matrix factorization, tensor factorization, etc. He is interested in combining matrix factorization techniques with topic models to improve, for example, recommendation systems.
  • Natural Language Processing. He has worked in the NLP group at Macquarie University for about four years. He is interested in how to utlise different lingustic features in topic modelling.
