Superiorization vs. Accelerated Convex Optimization: The Superiorized/Regularized Least-Squares Case
Yair Censor, Stefania Petra, Christoph Schnörr
We conduct a study and comparison of superiorization and optimization approaches for the reconstruction problem of superiorized/regularized least-squares solutions of underdetermin…
An analysis of the superiorization method via the principle of concentration of measure
Yair Censor, Eliahu Levy
The superiorization methodology is intended to work with input data of constrained minimization problems, i.e., a target function and a constraints set. However, it is based on an…
Convergence Analysis of Processes with Valiant Projection Operators in Hilbert Space
Yair Censor, Rafiq Mansour
Convex feasibility problems require to find a point in the intersection of a finite family of convex sets. We propose to solve such problems by performing set-enlargements and appl…
The Implicit Convex Feasibility Problem and Its Application to Adaptive Image Denoising
Yair Censor, Aviv Gibali, Frank Lenzen +1
The implicit convex feasibility problem attempts to find a point in the intersection of a finite family of convex sets, some of which are not explicitly determined but may vary. We…
