Dr. Lu’s general area of research is data information modeling and knowledge learning in support of business decision making. His primary research interest is on TREE (Transparent, Reliable, Efficient and Effective) Bayesian analytic models for data information processing. He is especially interested in general-purpose Bayesian inference algorithms for regularizing machine and statistical learning models with subjective prior knowledge. His secondary research interest is in social network analysis for understanding online information diffusion.
