| Abstract(in English) | Use of nommonotonic neurons in autoassociative memories greatly improves retrieval properties, such as enlargement of basins of attraction, enhanced storage capacity, and the existence of the so-called superretrieval states where "perfect" retrieval of a memorized pattern is possible. Coolen-Sherrington (CS)theory, which has been proposed to describe retrieval dynamics of ordinary models without non-monotonicity, also describes the models with nonmonotonicity approximately well. In this study, we analyze the superretrieval states by CS theory, and show the region where superretrieval is possible. It is observed that the region where superretrieval state is reachable by simulation is narrower than the region where superretrieval is analytically predicted to be possible by CS theory. We also discuss the reason for this observation. |
