Generalized cross validation for ℓp-ℓq minimization

HIGHLIGHTS

• who: Alessandro Buccini from the Department of Mathematics and Computer Science, University of Cagliari, Cagliari, Italy have published the paper: Generalized cross validation for u2113p-u2113q minimization, in the Journal: (JOURNAL)
• what: The authors compare generalized cross validation with two other approaches to selecting the regularization parameter in_(2), including cross validation as described and the discrepancy principle as discussed. The authors show the true phantom and the sinogram in Fig 2. The authors report the results obtained in Table 1. The authors propose the GCV method for choosing the regularization parameter for the p . . .
