A Self-organizing Neural Network for Learning A Body-centered Invariant Representation of 3-D Target Position
This paper describes a self-organizing neural network that learns a body-centered representation of 3-D target positions. This representation remains invariant under head and eye movements, and is a key component of sensory-motor systems for producing motor equivalent reaches to targets . Learning requires no teacher, instead utilizing information gained from an action-perception cycle in which head movements are made while a stationary target is foveated. Because the spatial representations used relate closely to neck anatomy, the network learns very rapidly, converging after foveating only 200 targets.
