Non-intrusive Nonlinear Model Reduction via Machine Learning Approximations to Low-dimensional Operators

  title={Non-intrusive Nonlinear Model Reduction via Machine Learning Approximations to Low-dimensional Operators},
  author={Zhe Bai and Liqian Peng},
Although projection-based reduced-order models (ROMs) for parameterized nonlinear dynamical systems have demonstrated exciting results across a range of applications, their broad adoption has been limited by their intrusivity: implementing such a reduced-order model typically requires significant modifications to the underlying simulation code. To address this, we propose a method that enables traditionally intrusive reduced-order models to be accurately approximated in a nonintrusive manner… Expand


Non-Intrusive Inference Reduced Order Model for Fluids Using Deep Multistep Neural Network
A data-driven learning framework for reduced order modeling of fluid dynamics that optimally approximates the full order model in the low-dimensional space with a given supervised learning task and is significantly more accurate than standard projection-based approaches. Expand
Non-intrusive reduced order modeling of nonlinear problems using neural networks
We develop a non-intrusive reduced basis (RB) method for parametrized steady-state partial differential equations (PDEs). The method extracts a reduced basis from a collection of high-fidelityExpand
Constrained sparse Galerkin regression
The sparse identification of nonlinear dynamics (SINDy) is a recently proposed data-driven modelling framework that uses sparse regression techniques to identify nonlinear low-order models and extends it to enforce physical constraints in the regression, e.g. energy-preserving quadratic nonlinearities.

Data-driven operator inference for nonintrusive projection-based model reduction
Abstract This work presents a nonintrusive projection-based model reduction approach for full models based on time-dependent partial differential equations. Projection-based model reductionExpand
Non-intrusive reduced order modeling of unsteady flows using artificial neural networks with application to a combustion problem
The proposed reduced-basis method, referred as the POD-NN, fully decouples the online stage and the high-fidelity scheme, and is thus able to provide fast and reliable solutions of complex unsteady flows. Expand
Machine Learning-augmented Predictive Modeling of Turbulent Separated Flows over Airfoils
By incorporating data that can reveal the form of the innate model discrepancy, the applicability of data-driven turbulence models can be extended to more general flows. Expand
Projection-based model reduction: Formulations for physics-based machine learning
The case studies demonstrate the importance of embedding physical constraints within learned models, and highlight the important point that the amount of model training data available in an engineering setting is often much less than it is in other machine learning applications, making it essential to incorporate knowledge from physical models.

A method for interpolating on manifolds structural dynamics reduced‐order models
A rigorous method for interpolating a set of parameterized linear structural dynamics reduced-order models (ROMs) is presented. By design, this method does not operate on the underlying set ofExpand
Recovering missing CFD data for high-order discretizations using deep neural networks and dynamics learning
The objective of this work is to accurately recover missing CFD data a posteriori at any time instance, given that the solution has been written to disk at only a relatively small number of time instances. Expand
Galerkin v. least-squares Petrov-Galerkin projection in nonlinear model reduction
In numerical experiments carried out on a turbulent compressible-flow problem with over one million unknowns, it is shown that increasing the time step to an intermediate value decreases both the error and the simulation time of the LSPG reduced-order model by an order of magnitude. Expand
