Congratulations to Rudy Geelen for having his paper Localized non-intrusive reduced-order modeling in the operator inference framework accepted for publication in Philosophical Transactions of the Royal Society A. The paper presents data-driven learning of localized reduced models. Instead of a global reduced basis, the approach employs multiple local approximation subspaces. This localization permits adaptation of a reduced model to local dynamics, thereby keeping the reduced dimension small. This is particularly important for reduced models of nonlinear systems of partial differential equations, where the solution may be characterized by different physical regimes or exhibit high sensitivity to parameter variations. Localization has been used in a number of model reduction approaches in the past; the key contribution here is the non-intrusive formulation via Operator Inference.

Congratulations to Parisa Khodabakhshi for having her paper Non-intrusive data-driven model reduction for differential algebraic equations derived from lifting transformations accepted for publication in Computer Methods in Applied Mechanics and Engineering. The paper presents a non-intrusive data-driven approach for model reduction of nonlinear systems. The approach considers the particular case of nonlinear PDEs that form systems of partial differential algebraic equations when lifted to polynomial form. Such systems arise, for example, when the governing equations include Arrhenius reaction terms (e.g., in reacting flow models) and thermodynamic terms (e.g., the Helmholtz free energy terms in a phase-field solidification model).

Congratulations to PhD student Michael Kapteyn for having his paper A Probabilistic Graphical Model Foundation for Enabling Predictive Digital Twins at Scale published in Nature Computational Science. This paper proposes a probabilistic graphical model as a formal mathematical representation of a digital twin and its associated physical asset. This formulation naturally integrates data, predictive models, and decisions. We illustrate the approach by building a structural digital twin of our group's unmanned aerial vehicle (UAV) hardware asset and show how the digital twin enables dynamic mission re-planning in response to in-flight structural damage.

Our perspective Scaling Digital Twins from the Artisanal to the Industrial was published in Nature Computational Science. This opinion piece makes the case that advancing the mathematical and algorithm foundations is essential to achieving digital twins at scale. It draws from examples in cardiology and aerospace engineering.

February 2020

Congratulations to Elizabeth Qian for having her paper Lift & Learn: Physics-informed machine learning for large-scale nonlinear dynamical systems accepted for publication in Physica D: Nonlinear Phenomena. The paper lays the theoretical foundations for a new physics-informed machine learning method for systems governed by nonlinear partial differential equations. The Lift & Learn method uses lifting transformations, which introduce auxiliary variables to expose polynomial structure. This polynomial structure is exploited to achieve non-intrusive learning from simulation snapshot data, through the lens of projection (which preserves polynomial structure). Elizabeth's analysis of the method shows that in some settings Lift & Learn models recover the generalization accuracy of intrusive projection-based reduced models.
