Fast and robust fixed-point algorithms for independent component analysis

by Aapo Hyvärinen - IEEE TRANS. NEURAL NETW , 1999
"... Independent component analysis (ICA) is a statistical method for transforming an observed multidimensional random vector into components that are statistically as independent from each other as possible. In this paper, we use a combination of two different approaches for linear ICA: Comon’s informat ..."

variance. Finally, we introduce simple fixed-point algorithms for practical optimization of the contrast functions. These algorithms optimize the contrast functions very fast and reliably.

Guarded Fixed Point Logic

by Erich Grädel, Igor Walukiewicz , 1999
"... Guarded fixed point logics are obtained by adding least and greatest fixed points to the guarded fragments of firstorder logic that were recently introduced by Andr eka, van Benthem and N emeti. Guarded fixed point logics can also be viewed as the natural common extensions of the modal µ-calculus an ..."

On Approximate Fixed Point Property and Fixed Points

by Anoop S. K, K. T. Ravindran
"... Abstract: In this paper we will prove the existence of fixed points and approximate eigenvalues to certain type of nonexpansive mappings using the existence of ε-fixed points to these maps. Also we will prove that if a Banach space has approximate fixed point property, then its dense subset also has ..."
