Gaussian process learning of nonlinear dynamics

1 code implementation19 Dec 2023 Dongwei Ye, Mengwu Guo

Through a Bayesian scheme, a probabilistic estimate of the model parameters is given by the posterior distribution, and thus a quantification is facilitated for uncertainties from noisy state data and the learning process.

Bayesian approach to Gaussian process regression with uncertain inputs

no code implementations19 May 2023 Dongwei Ye, Mengwu Guo

Considering two types of observables -- noise-corrupted outputs with fixed inputs and those with prior-distribution-defined uncertain inputs, a posterior distribution is estimated via a Bayesian framework to infer the uncertain data locations.

Data-driven reduced-order modelling for blood flow simulations with geometry-informed snapshots

1 code implementation21 Feb 2023 Dongwei Ye, Valeria Krzhizhanovskaya, Alfons G. Hoekstra

Parametric reduced-order modelling often serves as a surrogate method for hemodynamics simulations to improve the computational efficiency in many-query scenarios or to perform real-time simulations.

Uncertainty quantification of a three-dimensional in-stent restenosis model with surrogate modelling

no code implementations11 Nov 2021 Dongwei Ye, Pavel Zun, Valeria Krzhizhanovskaya, Alfons G. Hoekstra

An uncertainty quantification of a model for In-Stent Restenosis with four uncertain parameters (endothelium regeneration time, the threshold strain for smooth muscle cells bond breaking, blood flow velocity and the percentage of fenestration in the internal elastic lamina) is presented.
