Normalized Random Measures and Extensions
The normalized random measure is a large class of random probability measures that has appealing properties and wide applications in Bayesian nonparametrics. In this talk I will review the Poisson process, completely random measures, and how to construct normalized random measure from them. I will then talk about its posterior characterization,
and how to construct dependent normalized random measures from it, e.g., spatial normalized random measures and mixed normalized random measures. I then will show the applications of the dependent normalized random measures in topic models. Some other potential applications will be discussed as well.
