Optimal Unsupervised Motor Learning Predicts the Internal Representation of Barn Owl Head Movements

Thisimplies the existence of a set of orthogonal internal coordinates thatare related to meaningful coordinates of the external world. No coherent computational theory has yet been proposed to explain this finding. I have proposed a simple model which provides aframework for a theory of low-level motor learning. I show that the theory predicts the observed microstimulation results in the barn owl. The model rests on the concept of "Optimal Un supervised Motor Learning", which provides a set of criteria that predict optimal internal representations. I describe two iterative Neural Network algorithms which find the optimal solution and demonstrate possible mechanisms for the development of internal representations in animals. 1 INTRODUCTION In the sensory domain, many algorithms for unsupervised learning have been proposed. Thesealgorithms learn depending on statistical properties of the input data, and often can be used to find useful "intermediate" sensory representations 614 Bam Owl Head Movements 615
