Functional Estimation of the Marginal Likelihood

Omiros Papaspiliopoulos, Timothée Stumpf-Fétizon, Jonathan Weare

We propose a framework for computing, optimizing and integrating with respect to a smooth marginal likelihood in statistical models that involve high-dimensional parameters/latent…

Conjugate gradient methods for high-dimensional GLMMs

Andrea Pandolfi, Omiros Papaspiliopoulos, Giacomo Zanella

Generalized linear mixed models (GLMMs) are a widely used tool in statistical analysis. The main bottleneck of many computational approaches lies in the inversion of the high dimen…

Partially factorized variational inference for high-dimensional mixed models

Max Goplerud, Omiros Papaspiliopoulos, Giacomo Zanella

While generalized linear mixed models are a fundamental tool in applied statistics, many specifications, such as those involving categorical factors with many levels or interaction…

Inference for multiple treatment effects using confounder importance learning

Omiros Papaspiliopoulos, David Rossell, Miquel Torrens-i-Dinarès

We address modelling and computational issues for multiple treatment effect inference under many potential confounders. Our main contribution is providing a trade-off between preve…

Scalable Bayesian computation for crossed and nested hierarchical models

Omiros Papaspiliopoulos, Timothée Stumpf-Fétizon, Giacomo Zanella

We develop sampling algorithms to fit Bayesian hierarchical models, the computational complexity of which scales linearly with the number of observations and the number of paramete…

Exact inference for a class of non-linear hidden Markov models on general state spaces

Guillaume Kon Kam King, Omiros Papaspiliopoulos, Matteo Ruggiero

Exact inference for hidden Markov models requires the evaluation of all distributions of interest - filtering, prediction, smoothing and likelihood - with a finite computational ef…
