Iterative Subgradient Projection Algorithm

2016
In this chapter we study convergence of iterative subgradient projection algorithms for solving convex feasibility problems in a general Hilbert space. Our goal is to obtain an approximate solution of the problem in the presence of computational errors.

A projection iterative algorithm for strong vector equilibrium problem

Optimization, 2014
In this paper, iterative algorithm for strong vector equilibrium problem (SVEP) is studied. Firstly, an auxiliary problem for SVEP is introduced and the relationships between these two problems are discussed. Then, based on the auxiliary problem, a projection iterative algorithm for SVEP is proposed.

Iterative projection algorithms for reconstructing compact binary images

SPIE Proceedings, 2008
An algorithm is described for reconstructing compact binary images from limited Fourier amplitude data. This problem arises in macromolecular crystallography where one wishes to reconstruct the molecular envelope from crystal x-ray diffraction amplitudes using a solvent contrast series.

Convergence of Picard’s iteration using projection algorithm for noncyclic contractions

Indagationes Mathematicae, 2019
This paper deals with some of the conditions for the convergence of Picard's iteration for non-cyclic contractions using a projection algorithm in uniformly convex Banach spaces. The author also discusses the existence of common best proximity pairs for a couple of non-cyclical mappings. Some examples are given to illustrate the main conclusions.

Mixed-Norm Projection-Based Iterative Algorithm for Face Recognition

2019
In this paper, the mixed-norm optimization is investigated for sparse signal reconstruction. Furthermore, an iterative optimization algorithm based on the projection method is presented for face recognition. From the theoretical point of view, the optimality and convergence of the proposed algorithm is strictly proved. And from the application point of

An improved iterative back projection algorithm based on ringing artifacts suppression

Neurocomputing, 2015
In order to suppress and reduce the ringing artifacts of the IBP super resolution algorithm, an improved iterative back projection (IBP) reconstruction algorithm is presented in this paper. Firstly, two novel concepts, variation and local variance variation based on an adaptive analysis are introduced.

An Iterative Projection Algorithm and Some Simulation Results

1996
An iterative projection method for large linear equation systems is described. It has favourable properties with respect to many statistical applications. A major advantage is that convergence can be established without restrictions on the system matrix. Hence diagonal dominance or regularity are not required.

An iterative algorithm for multi-user inference channel based on subspace projection

International Journal of Wireless and Mobile Computing, 2012
Considering a Multiple Input Multiple Output (MIMO) interference channel with K-user pairs, an iterative algorithm based on projection is proposed. In this algorithm, the objective function is the weighted sum of leakage of interference and desired signal out of their corresponding subspace.
