$Φ$-DVAE: Physics-Informed Dynamical Variational Autoencoders for Unstructured Data Assimilation

no code implementations30 Sep 2022 Alex Glyn-Davies, Connor Duffin, Ö. Deniz Akyildiz, Mark Girolami

To address these shortcomings, in this paper we develop a physics-informed dynamical variational autoencoder ($\Phi$-DVAE) to embed diverse data streams into time-evolving physical systems described by differential equations.

Uncertainty Quantification

Statistical Finite Elements via Langevin Dynamics

1 code implementation21 Oct 2021 Ömer Deniz Akyildiz, Connor Duffin, Sotirios Sabanis, Mark Girolami

Through embedding uncertainty inside of the governing equations, finite element solutions are updated to give a posterior distribution which quantifies all sources of uncertainty associated with the model.
