Boolean neural nets are observable

Abstract

It is shown that arbitrary locally finite discrete neural networks are observable (have the shadowing property) in the sense that pseudo-orbits obtained by small perturbations of an orbit are approximated by actual orbits. The model includes discretizations of analog networks, arbitrary cellular automata, and a wide generalization of linear maps on a one dimensional grid. It follows that the true qualitative behavior of dynamical systems can be observed to infinite precision on computer simulations, despite unavoidable discretization and approximation errors. © 1994.
