Abstract

The problem of simulation of automata by neural networks is investigated. In the case of discrete networks with polynomially bounded weights, the optimal lower and upper bounds for the number of neurons necessary to simulate any finite automata of size n are presented. For the analog case we prove the 15-neuron upper bound for any finite automaton. By extending this construction we show that a 25-neuron network may simulate any Turing machine, and hence its behavior is undecidable.
