Data-based Discovery of Governing Equations

no code implementations5 Dec 2020 Waad Subber, Piyush Pandita, Sayan Ghosh, Genghis Khan, Liping Wang, Roger Ghanem

Without a prior definition of the model structure, first a free-form of the equation is discovered, and then calibrated and validated against the available data.

Probabilistic learning on manifolds constrained by nonlinear partial differential equations for small datasets

no code implementations27 Oct 2020 Christian Soize, Roger Ghanem

The presented PLoM constrained by PDE allows for generating a large number of learned realizations of the stochastic process and its corresponding random control parameter.

Normal-bundle Bootstrap

1 code implementation27 Jul 2020 Ruda Zhang, Roger Ghanem

Probabilistic models of data sets often exhibit salient geometric structure.

Data-driven discovery of free-form governing differential equations

no code implementations27 Sep 2019 Steven Atkinson, Waad Subber, Liping Wang, Genghis Khan, Philippe Hawi, Roger Ghanem

We present a method of discovering governing differential equations from data without the need to specify a priori the terms to appear in the equation.
