TL;DR

A new procedure for hierarchical training of multilayer perceptrons to outputs of high precision achieves a dramatic increase in accuracy, e.g. by three orders of magnitude, and can reduce training time considerably.

Abstract

We present a new procedure for hierarchical training of multilayer perceptrons to outputs of high precision. It achieves a dramatic increase in accuracy, e.g. by three orders of magnitude, and can reduce training time considerably. The method is applied to the prediction of chaotic systems where we obtain the optimum error evolution for iterated predictions as well as a substantial reduction of the absolute prediction error.
