Feedback Can Reduce the Specification Complexity of Motor Programs

Abstract

In this paper we show that when it is possible to use feedback in the specifications of "motor programs", the length of the descriptions of the instruction sequences for carrying out a given task can be reduced by a factor that reflects the richness of the available feedback signals. The model on which this work is based is that of a finite automaton, modified in such a way that instruction processing is akin to the way in which difference or differential equations "process" piecewise constant inputs.
