A Hybrid Gradient-Projection Algorithm for Averaged Mappings in Hilbert Spaces
Journal of Applied Mathematics, 2012 It is well known that the gradient-projection algorithm (GPA) is very useful in solving constrained convex minimization problems. In this paper, we combine a general iterative method with the gradient-projection algorithm to propose a hybrid gradient ...

Coordinate Descent Iterations in Pseudo Affine Projection Algorithm [PDF]
2005 IEEE International Symposium on Circuits and Systems, 2005 This paper introduces a new affine projection algorithm based on the dichotomous coordinate descent algorithm. A generalization for simplified Volterra filters is also made and its stability is improved by using a voice activity detector. The performance of the proposed algorithms for acoustic echo cancellation is assessed.

Projection regularization algorithm for solving linear algebraic system of large dimension
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2010 The iterative projection algorithm for solving ill-posed systems of linear algebraic equations is examined. This algorithm is based on transforming the regularized normal equations to the equivalent augmented regularized normal system of equations.
