Title: Hierarchical Bayesian modeling: models and inference algorithms
Hierarchical Bayesian models have become a popular tool for analyzing
large-scale real-world data, such as text and images. Through these
models, people can build useful tools for latent structure discovery,
browsing and recommendations. In this talk, I will present several
recent advances in the area of hierarchical Bayesian modeling, with an
emphasis on topic modeling, Bayesian nonparametrics and approximate
posterior inference. Specifically, I will talk about a novel model on
recommending scientific articles that provides an interpretable latent
structure for both users and items in a recommender system and then
present an online variational inference algorithm that scales up to
millions of articles on a single machine and also does model
selection. Finally, I will summarize with some ongoing work.
