Conditional Korhunen-Loéve regression model with Basis Adaptation for high-dimensional problems: uncertainty quantification and inverse modeling

Yu-Hong Yeung, Ramakrishna Tipireddy, David A. Barajas-Solano +1

We propose a methodology for improving the accuracy of surrogate models of the observable response of physical systems as a function of the systems' spatially heterogeneous paramet…

AMPS: An Augmented Matrix Formulation for Principal Submatrix Updates with Application to Power Grids

Yu-Hong Yeung, Alex Pothen, Mahantesh Halappanavar +1

We present AMPS, an augmented matrix approach to update the solution to a linear system of equations when the matrix is modified by a few elements within a principal submatrix. Thi…
