Bayesian Triangulation Splines: Spatial Adaptation on Irregular Domains
Sihyeon Pyeon, Sunwoo Lim, Seonghyun Jeong
Conventional nonparametric regression methods for two-dimensional non-rectangular domains often overlook domain geometry and allow smoothing across boundaries. In spatial and geost…
Laplace Variational Inference for Dirichlet Process Mixtures of Marked Poisson Point Processes
Minsung Choi, Seonghyun Jeong
Marked point process data arise when events occur in a space with event-level marks. We study clustering of replicated marked Poisson point processes and introduce Dirichlet proces…
Infection dynamics for fluctuating infection or removal rates regarding the number of infected and susceptible individuals
Seong Jun Park, M. Y. Choi
In general, the rates of infection and removal (whether through recovery or death) are nonlinear functions of the number of infected and susceptible individuals. One of the simples…
Bayesian Nonparametric Modeling for Multivariate Conditional Copula Regression with Varying Coefficients
Yujin Jeong, Seonghyun Jeong
Multivariate mixed-type outcomes are difficult to model jointly, and additional complexity arises when both marginal effects and dependence structures vary with a covariate such as…
