Bayesian Point Set Registration
Adam Spannaus, Vasileios Maroulas, David J. Keffer +1
Point set registration involves identifying a smooth invertible transformation between corresponding points in two point sets, one of which may be smaller than the other and possib…
Unbiased inference for discretely observed hidden Markov model diffusions
Neil K. Chada, Jordan Franks, Ajay Jasra +2
We develop a Bayesian inference method for diffusions observed discretely and with noise, which is free of discretisation bias. Unlike existing unbiased inference methods, our meth…
Certified dimension reduction in nonlinear Bayesian inverse problems
Olivier Zahm, Tiangang Cui, Kody Law +2
We propose a dimension reduction technique for Bayesian inverse problems with nonlinear forward operators, non-Gaussian priors, and non-Gaussian observation noise. The likelihood f…
Markov chain Simulation for Multilevel Monte Carlo
Ajay Jasra, Kody Law, Yaxian Xu
This paper considers a new approach to using Markov chain Monte Carlo (MCMC) in contexts where one may adopt multilevel (ML) Monte Carlo. The underlying problem is to approximate e…
Multi-Index Sequential Monte Carlo Methods for partially observed Stochastic Partial Differential Equations
Yaxian Xu, Ajay Jasra, Kody J. H. Law
In this paper we consider sequential joint state and static parameter estimation given discrete time observations associated to a partially observed stochastic partial differential…
Single atom force measurements: mapping potential energy landscapes via electron beam induced single atom dynamics
Ondrej Dyck, Feng Bao, Maxim Ziatdinov +8
In the last decade, the atomically focused beam of a scanning transmission electron microscope (STEM) was shown to induce a broad set of transformations of material structure, open…
