Wasserstein Gaussianization and Efficient Variational Bayes for Robust Bayesian Synthetic Likelihood

1 code implementation24 May 2023 Nhat-Minh Nguyen, Minh-Ngoc Tran, Christopher Drovandi, David Nott

We combine the Wasserstein Gaussianization transformation with robust BSL, and an efficient Variational Bayes procedure for posterior approximation, to develop a highly efficient and reliable approximate Bayesian inference method for likelihood-free problems.

Efficient computational methods for high-dimensional Bayesian inference are developed using Gaussian variational approximation, with a parsimonious but flexible factor parametrization of the covariance matrix.
