Shadowing and prediction of dynamical systems

Autor: D. W. Pearson

Publikováno v: Mathematical and Computer Modelling. 34(7-8):813-820

In this paper, we illustrate how the notion of shadowing can be applied to the prediction problem for dynamical systems. We start with the assumption that we observer a sequence of states from a dynamical system and that we have identified a reasonab

Ehresmann connections and feedforward neural networks

Autor: D. W. Pearson

Publikováno v: Mathematical and Computer Modelling. 29:17-25

In this paper, we describe how Ehresmann connections can be used to study certain properties of feedforward neural networks. Essentially, we calculate a Lie group approximation to the structure of the inverse image set above a certain point in the ou
