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.

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.

Characteristics of iterative projection algorithms

SPIE Proceedings, 2012
A brief description of various iterative projection algorithms and the relationships between them is given, along with some possible reasons for their ability to solve non-convex problems. An empirical model of their behaviour when applied to non-convex problems is also described.

Event-Triggered Cooperative Model-Free Adaptive Iterative Learning Control for Multiple Subway Trains With Actuator Faults

IEEE Transactions on Cybernetics, 2023
This article investigates the issue of speed tracking and dynamic adjustment of headway for the repeatable multiple subway trains (MSTs) system in the case of actuator faults.

Iterative Projection Approximation Algorithms for PCA

2006 IEEE International Conference on Acoustics Speed and Signal Processing Proceedings, 2006
In this paper we introduce a new error measure, integrated reconstruction error (IRE), the minimization of which leads to principal eigenvectors (without rotational ambiguity) of the data covariance matrix. Then we present iterative algorithms for the IRE minimization, through the projection approximation.

A Fast Approximate Check Polytope Projection Algorithm for ADMM Decoding of LDPC Codes

IEEE Communications Letters, 2019
Simplifying the Euclidean projection onto check polytope is an efficient way to reduce the computational complexity of alternating direction method of multipliers (ADMM) decoding algorithm for low-density parity-check (LDPC) codes.

Iterative projection algorithms in protein crystallography. I. Theory

Acta Crystallographica Section A Foundations of Crystallography, 2013
A general class of iterative projection algorithms is described and proposed as a tool for phasing in protein crystallography in order to improve the radius of convergence over that of conventional density-modification algorithms. Their relationship to conventional density modification is described.
