Hypoelliptic diffusions: filtering and inference from complete and partial observations

S Ditlevsen, A Samson - Journal of the Royal Statistical Society …, 2019 - academic.oup.com
The statistical problem of parameter estimation in partially observed hypoelliptic diffusion
processes is naturally occurring in many applications. However, because of the noise …

Bayesian estimation of discretely observed multi-dimensional diffusion processes using guided proposals

F van der Meulen, M Schauer - 2017 - projecteuclid.org
Estimation of parameters of a diffusion based on discrete time observations poses a difficult
problem due to the lack of a closed form expression for the likelihood. From a Bayesian …

[HTML][HTML] A two-variable model robust to pacemaker behaviour for the dynamics of the cardiac action potential

C Corrado, SA Niederer - Mathematical Biosciences, 2016 - Elsevier
Ionic models with two state variables are routinely used in patient specific electro-physiology
simulations due to the small number of parameters to be constrained and their …

Data augmentation for diffusions

O Papaspiliopoulos, GO Roberts… - Journal of Computational …, 2013 - Taylor & Francis
The problem of formal likelihood-based (either classical or Bayesian) inference for discretely
observed multidimensional diffusions is particularly challenging. In principle, this involves …

Parametric inference for hypoelliptic ergodic diffusions with full observations

A Melnykova - Statistical Inference for Stochastic Processes, 2020 - Springer
Multidimensional hypoelliptic diffusions arise naturally in different fields, for example to
model neuronal activity. Estimation in those models is complex because of the degenerate …

Optimal control for estimation in partially observed elliptic and hypoelliptic linear stochastic differential equations

Q Clairon, A Samson - Statistical Inference for Stochastic Processes, 2020 - Springer
Multi-dimensional stochastic differential equations (SDEs) are a powerful tool to describe
dynamics of phenomena that change over time. We focus on the parametric estimation of …

Fluidic FitzHugh-Nagumo oscillator

M Fromm, S Grundmann, A Seifert - Physics of Fluids, 2025 - pubs.aip.org
Fluidic oscillators display a unique feature: from a constant input flow, they generate an
output that alternates both temporally and spatially, all without the necessity for any moving …

Inference for biomedical data by using diffusion models with covariates and mixed effects

MG Ruse, A Samson, S Ditlevsen - Journal of the Royal …, 2020 - academic.oup.com
Neurobiological data such as electroencephalography measurements pose a statistical
