Koopman Reduced-Order Modeling with Confidence Bounds
SIAM Journal on Applied Dynamical SystemsThis paper introduces a reduced order modeling technique based on Koopman operator theory that gives confidence bounds on the model's predictions. It is based on a data-driven spectral decomposition of the Koopman operator. The reduced order model is constructed using a finite number of Koopman eigenvalues and modes, while the rest of spectrum is ...

Development of a Reduced Order Model for Turbine Blade Cooling Design
International Journal of Turbomachinery, Propulsion and PowerRotating detonation engines (RDEs) are expected to have higher specific work and efficiency, but the high-temperature transonic flow delivered by the combustor poses relevant design and technological difficulties.

Reduced-Order modeling for Heston stochastic volatility model
Hacettepe Journal of Mathematics and StatisticsIn this paper, we compare the intrusive proper orthogonal decomposition (POD) with Galerkin projection and the data-driven dynamic mode decomposition (DMD), for Heston's option pricing model. The full order model is obtained by discontinuous Galerkin discretization in space and backward Euler in time.

Nonintrusive reduced order models
, 2018 Le but de cette thèse est de construire des modèles réduits permettant de se substituer à des logiciels de simulation de systèmes physiques complexes. Ces modèles réduits devront être rapides à interroger et seront identifiés sur la base d’un nombre limité de calculs issus du logiciel de simulation.
