Statistical Finite elements for misspecified models

8 January 2021

Connor Duffin, Edward Cripps, Thomas Stemler and Mark Girolami have recently published in PNAS, their paper entitled Statistical finite elements for misspecified models. Science and engineering have benefited greatly from the ability of finite element methods (FEMs) to simulate nonlinear, time-dependent complex systems. The recent advent of extensive data collection from such complex systems now raises the question of how to systematically incorporate these data into finite element models, consistently updating the solution in the face of mathematical model misspecification with physical reality. This article describes general and widely applicable methodology for the coherent synthesis of data with FEM models, providing a data-driven probability distribution that captures all sources of uncertainty in the pairing of FEM with measurements.

Reversible Jump PDMP Samplers for Variable Selection

27 October 2020

Augustin Chevallier, Paul Farnhead and Matthew Sutton have recently published on Arxiv, their paper entitled Reversible Jump PDMP Samplers for Variable Selection. This paper looks at how to extend recent PDMP samplers to model choice problems, and in particular variable selection. It gives a general recipe for adding appropriate reversible jump moves which allow exploration of different models by adding or removing variables from the model.

BayesComp 2020

24 January 2020

From 7-10 January 2020 the biannual ISBA meeting on Bayesian Computation (BayesComp) was held at the University of Florida, Gainsville, organised by Jim Hobert and colleagues. The meeting was particularly well-attended by members of the CoSInES project. A list of CoSInES-affiliated attendees includes: PIs Prof. Gareth Roberts, Prof. Christophe Andrieu, Prof. Paul Fearnhead and Dr. Anthony Lee who all gave talks, and research associates Dr. Augustin Chevalier, Dr. Lionel Riou-Durand and Dr. Andi Wang who all presented posters. Overarching scientific themes from the meeting included the analysis of computational Bayesian methods in high-dimensional settings, study of nonreversible sampling methods and the study of robustness and approximate methods. A notable presentation was the opening plenary talk, given by CoSInES PI Prof. Paul Fearnhead on ‘Continuous-time MCMC’, focusing on the Zig-Zag Sampler and related developments. The location was particularly pleasant; the days were sunny and relatively warm (despite being winter in Florida), and the meeting was held in the beautiful University of Florida campus, with a large lake (home to alligators, though none were spotted) and within easy walking distance of the lively Gainesville town centre.


Job opportunities

10 January 2020

There is still time to apply to be part of the CoSInES team, with applications closing on 20th January 2020 for the position of Postdoctoral Research Assistant in Computational Statistics and Statistical Machine Learning at the University of Oxford.
