Convergence Analysis of Schr{ö}dinger-F{ö}llmer Sampler without Convexity
Yuling Jiao, Lican Kang, Yanyan Liu +1
Schrödinger-Föllmer sampler (SFS) is a novel and efficient approach for sampling from possibly unnormalized distributions without ergodicity. SFS is based on the Euler-Maruyama dis…
Integral representation of probabilities in Kingman coalescent
Youzhou Zhou
Kingman Coalescent was first proposed by Kingman [7] in population genetics to describe population's genealogical structure. Now it becomes a bench-mark model for coalescent proces…
Some Moderate Deviations for Ewens-Pitman Sampling Model
Youzhou Zhou
Ewens-Pitman model has been successfully applied to various fields including Bayesian statistics. There are four important estimators ,. I…
Limit Theorems Associated With The Pitman-Yor Process
Shui Feng, Fuqing Gao, Youzhou Zhou
The Pitman-Yor process is a random discrete measure. The random weights or masses follow the two-parameter Poisson-Dirichlet distribution with parameters . The paramet…
