Noise representation in residuals of LSQR, LSMR, and CRAIG regularization
Iveta Hnětynková, Marie Kubínová, Martin Plešinger
Golub-Kahan iterative bidiagonalization represents the core algorithm in several regularization methods for solving large linear noise-polluted ill-posed problems. We consider a ge…
