Applications of Koopman Mode Analysis to Neural Networks
Iva Manojlović, Maria Fonoberova, Ryan Mohr +4
We consider the training process of a neural network as a dynamical system acting on the high-dimensional weight space. Each epoch is an application of the map induced by the optim…
Numerical methods for accurate computation of the eigenvalues of Hermitian matrices and the singular values of general matrices
Zlatko Drmač
This paper offers a review of numerical methods for computation of the eigenvalues of Hermitian matrices and the singular values of general and some classes of structured matrices.…
Revisiting IRKA: Connections with pole placement and backward stability
C. Beattie, Z. Drmac, S. Gugercin
The iterative rational Krylov algorithm (\textsf{IRKA}) is a popular approach for producing locally optimal reduced-order -approximations to linear time-invariant (L…
New robust ScaLAPACK routine for computing the QR factorization with column pivoting
Zvonimir Bujanović, Zlatko Drmač
In this note we describe two modifications of the ScaLAPACK subroutines PxGEQPF for computing the QR factorization with the Businger-Golub column pivoting. First, we resolve a subt…
On least squares problems with certain Vandermonde--Khatri--Rao structure with applications to DMD
Zlatko Drmač, Igor Mezić, Ryan Mohr
This paper proposes a new computational method for solving structured least squares problems that arise in the process of identification of coherent structures in fluid flows. It i…
