The S/N Analysis of Associative Memory

There are some models of associative memory that have improved learning algorithms or dynamics. We obtained the memory capacity of an associative memory using the sign alternating memorization method and the pairing memorization method by means of self-consistent signal-to-noise analysis(SCSNA). In the case using the grouping memorization method, as the number of patterns of a group increases, the memory capacity increases. If more than about 10 patterns are grouped, the memory capacity is about 0.27 as well as the cross-correlation type.
