A Simple Hebbian/Anti-Hebbian Network Learns the Sparse, Independent Components of Natural Images
Article PDF (323.75 KB)
Abstract

Slightly modified versions of an early Hebbian/anti-Hebbian neural network are shown to be capable of extracting the sparse, independent linear components of a prefiltered natural image set. An explanation for this capability in terms of a coupling between two hypothetical networks is presented. The simple networks presented here provide alternative, biologically plausible mechanisms for sparse, factorial coding in early primate vision.
