Solving Independent Component Analysis Contrast Functions with Particle Swarm Optimization
Independent Component Analysis (ICA) is a statistical computation method that transforms a random vector in another one whose components are independent. Because the marginal distr...

Fast Image Recovery Using Variable Splitting and Constrained Optimization
We propose a new fast algorithm for solving one of the standard formulations of image restoration and reconstruction which consists of an unconstrained optimization problem where t...

Fault-Tolerant Broadcasting in Toroidal Networks
A non-redundant fault-tolerant broadcasting algorithm in a faulty k-ary n-cube is designed. The algorithm can adapt up to 2n,2 node failures. Compared to the optimal algorithm in a...
