Mixtures of Gaussian process experts based on kernel stick-breaking processes

1 code implementation26 Apr 2023 Yuji Saikai, Khue-Dung Dang

Capitalising on the recent advancement in the dependent Dirichlet processes literature, we propose a new mixture model of Gaussian process experts based on kernel stick-breaking processes.

Bayesian structural equation modeling for data from multiple cohorts

no code implementations22 Dec 2020 Khue-Dung Dang, Louise M. Ryan, Tugba Akkaya-Hocagil, Richard J. Cook, Gale A. Richardson, Nancy L. Day, Claire D. Coles, Heather Carmichael Olson, Sandra W. Jacobson, Joseph L. Jacobson

In this paper we show how a Bayesian approach can be used to fit a multi-group multi-level structural model that maps cognition to a broad range of observed variables measured at multiple ages.

Subsampling MCMC - An introduction for the survey statistician

no code implementations23 Jul 2018 Matias Quiroz, Mattias Villani, Robert Kohn, Minh-Ngoc Tran, Khue-Dung Dang

The rapid development of computing power and efficient Markov Chain Monte Carlo (MCMC) simulation algorithms have revolutionized Bayesian statistics, making it a highly practical inference method in applied work.

Subsampling Sequential Monte Carlo for Static Bayesian Models

no code implementations8 May 2018 David Gunawan, Khue-Dung Dang, Matias Quiroz, Robert Kohn, Minh-Ngoc Tran

SMC sequentially updates a cloud of particles through a sequence of distributions, beginning with a distribution that is easy to sample from such as the prior and ending with the posterior distribution.

Hamiltonian Monte Carlo with Energy Conserving Subsampling

no code implementations2 Aug 2017 Khue-Dung Dang, Matias Quiroz, Robert Kohn, Minh-Ngoc Tran, Mattias Villani

The key insight in our article is that efficient subsampling HMC for the parameters is possible if both the dynamics and the acceptance probability are computed from the same data subsample in each complete HMC iteration.

The block-Poisson estimator for optimally tuned exact subsampling MCMC

no code implementations27 Mar 2016 Matias Quiroz, Minh-Ngoc Tran, Mattias Villani, Robert Kohn, Khue-Dung Dang

A pseudo-marginal MCMC method is proposed that estimates the likelihood by data subsampling using a block-Poisson estimator.
