Learning in sensory systems takes place after a repeated exposure to the incoming signals and many ideas based on information theoretical principles have been proposed to explain the synaptic adaptation which improves the coding capabilities of sensory areas. In this paper we want to emphasize that a simple, natural learning rule can be derived from a careful treatment of image redundancies. The learning...
Much effort has been carried out to propose models of the early visual pathway based on the statistical analysis of natural images. These conventional frameworks lead to predictions on the RFs of simple cells which do not fit well their observed properties [D.L. Ringach, Spatial structure and symmetry of simple-cell receptive fields in macaque primary visual cortex, J. Neurophysiol. 2002 (2002) 455–463]...
