Embedded techniques for choosing the parameter in Tikhonov regularization

Silvia Gazzola, Paolo Novati, Maria Rosaria Russo

This paper introduces a new strategy for setting the regularization parameter when solving large-scale discrete ill-posed linear problems by means of the Arnoldi-Tikhonov method. T…

A GCV based Arnoldi-Tikhonov regularization method

Paolo Novati, Maria Rosaria Russo

For the solution of linear discrete ill-posed problems, in this paper we consider the Arnoldi-Tikhonov method coupled with the Generalized Cross Validation for the computation of t…
