A Probabilistic Graphical Model Foundation for Enabling Predictive Digital Twins at Scale

2 code implementations10 Dec 2020 Michael G. Kapteyn, Jacob V. R. Pretorius, Karen E. Willcox

The formal definition of this coupled system as a probabilistic graphical model enables us to draw upon well-established theory and methods from Bayesian statistics, dynamical systems, and control theory.

From Physics-Based Models to Predictive Digital Twins via Interpretable Machine Learning

no code implementations23 Apr 2020 Michael G. Kapteyn, Karen E. Willcox

In operation, the classifier uses observational data from the asset to infer which physics-based models in the model library are the best candidates for the updated digital twin.

mfEGRA: Multifidelity Efficient Global Reliability Analysis through Active Learning for Failure Boundary Location

no code implementations6 Oct 2019 Anirban Chaudhuri, Alexandre N. Marques, Karen E. Willcox

The method builds on the Efficient Global Reliability Analysis (EGRA) method, which is a surrogate-based method that uses adaptive sampling for refining Gaussian process surrogates for failure boundary location using a single-fidelity model.
