Abstract

This paper proposes a new approach to mental imagery that has the
potential for resolving an old debate. We show that the methods by
which fractals emerge from dynamical systems provide a natural
computational framework for the relationship between the "deep"
representations of long-term visual memory and the "surface"
representations of the visual array, a distinction which was proposed
by (Kosslyn, 1980). The concept of an iterated function system (IFS)
as a highly compressed representation for a complex topological set of
points in a metric space (Barnsley, 1988) is embedded in a
connectionist model for mental imagery tasks. Two advantages of this
approach over previous models are the capability for topological
transformations of the images, and the continuity of the deep
representations with respect to the surface representations.


To be published in the Proceedings of the Fourteenth Annual Conference
of the Cognitive Science Society, Bloomington, Indiana, July/August, 1992.
