Chopper model of pattern recognition
J. Leo van Hemmen, Aernout C. D. van Enter · Physical Review A · 1986
A simple model is proposed that allows an efficient storage and retrieval of random patterns. Also correlated patterns can be handled. The data are stored in an Ising-spin system with ferromagnetic interactions between all the spins and the main idea is to ``chop'' the system along the boundaries where the patterns differ.
