<<Two-parameter Dirichlet process and related dynamic models>>--孙玮教授

2017年12月06日，星期二上午10:00在大学城广州大学行政东楼后座310。加拿大Concordia University数学与统计系孙玮教授为各位学子带来了精彩的学术讲座--《Two-parameter Dirichlet process and related dynamic models》。

摘要:

The Dirichlet process appears as approximation to the equilibrium behavior of certain large populations evolving under the influence of mutation and random genetic drift. In this talk, we investigate stochastic dynamic models for the two-parameter Poisson-Dirichlet distribution and Dirichlet process. We construct reversible diffusions with the two-parameter Poisson-Dirichlet distribution and Dirichlet processas their stationary distributions. This talk is based on joint work with Shui Feng.
