Tensor regularization by truncated iteration: a comparison of some solution methods for large-scale linear discrete ill-posed problem with a t-product
Ugochukwu O. Ugwu, Lothar Reichel
This paper describes and compares some structure preserving techniques for the solution of linear discrete ill-posed problems with the t-product. A new randomized tensor singular v…
Tensor Arnoldi-Tikhonov and GMRES-type methods for ill-posed problems with a t-product structure
Lothar Reichel, Ugochukwu O. Ugwu
This paper describes solution methods for linear discrete ill-posed problems defined by third order tensors and the t-product formalism introduced in [M. E. Kilmer and C. D. Martin…
Weighted tensor Golub-Kahan-Tikhonov-type methods applied to image processing using a t-product
Lothar Reichel, Ugochukwu O Ugwu
This paper discusses weighted tensor Golub-Kahan-type bidiagonalization processes using the t-product. This product was introduced in [M. E. Kilmer and C. D. Martin, Factorization…
Communication in Complex Networks
Omar De la Cruz Cabrera, Jiafeng Jin, Silvia Noschese +1
One of the properties of interest in the analysis of networks is \emph{global communicability}, i.e., how easy or difficult it is, generally, to reach nodes from other nodes by fol…
Estimating and increasing the structural robustness of a network
Silvia Noschese, Lothar Reichel
The capability of a network to cope with threats and survive attacks is referred to as its robustness. This paper discusses one kind of robustness, commonly denoted structural robu…
