Real-time inverse solutions via neural matrix operators
Julie Pham, Thomas O'Leary-Roseberry, Omar Ghattas +1
Rapid data assimilation is required for real-time prediction and control in digital twins. For many physical systems, the data assimilation task requires the solution of a physics-…

Projection-based multifidelity linear regression for data-scarce applications
Vignesh Sella, Julie Pham, Karen Willcox +1
Surrogate modeling for systems with high-dimensional quantities of interest remains challenging, particularly when training data are costly to acquire. This work develops multifide…

Real-time aerodynamic load estimation for hypersonics via strain-based inverse maps
Julie Pham, Omar Ghattas, Noel Clemens +1
This work develops an efficient real-time inverse formulation for inferring the aerodynamic surface pressures on a hypersonic vehicle from sparse measurements of the structural str…
