Bayesian Numerical Methods for Nonlinear Partial Differential Equations

Junyang Wang, Jon Cockayne, Oksana Chkrebtii +2

The numerical solution of differential equations can be formulated as an inference problem to which formal statistical approaches can be applied. However, nonlinear partial differe…

Bayesian Inference for Polycrystalline Materials

James Matuk, Oksana Chkrebtii, Stephen Niezgoda

Polycrystalline materials, such as metals, are comprised of heterogeneously oriented crystals. Observed crystal orientations are modelled as a sample from an orientation distributi…

Elastic -means clustering of functional data for posterior exploration, with an application to inference on acute respiratory infection dynamics

Xiao Zang, Sebastian Kurtek, Oksana Chkrebtii +1

We propose a new method for clustering of functional data using a -means framework. We work within the elastic functional data analysis framework, which allows for decomposition…

Bayesian Framework for Simultaneous Registration and Estimation of Noisy, Sparse and Fragmented Functional Data

James Matuk, Karthik Bharath, Oksana Chkrebtii +1

In many applications, smooth processes generate data that is recorded under a variety of observation regimes, such as dense, sparse or fragmented observations that are often contam…

Inference for stochastic kinetic models from multiple data sources for joint estimation of infection dynamics from aggregate reports and virological data

Yury E. García, Oksana A. Chkrebtii, Marcos A. Capistrán and +1

Influenza and respiratory syncytial virus (RSV) are the leading etiological agents of seasonal acute respiratory infections (ARI) around the world. Medical doctors typically base t…

Automatic Detection and Uncertainty Quantification of Landmarks on Elastic Curves

Justin Strait, Oksana Chkrebtii, Sebastian Kurtek

A population quantity of interest in statistical shape analysis is the location of landmarks, which are points that aid in reconstructing and representing shapes of objects. We pro…
