| Abstract(in English) | In the model proposed by Amit et al. to explain the Miyashita's physiologic findings, the attractors that are mixtures of consecutively learned memory patterns become equilibrium states. It is thought that it is significant to store the relation information between the memory patterns as the correlated attractor in the brain, since the memory patterns continuously observed must be had mutually relation. On the other hand, when it is continuously observed the memory patterns coded the object images accidentally located in neighborhood, it is necessary to store each memory patterns individually. In this study, we examined the attractor's stability in the Amit model, when the learning order of the memory patterns gradually changes from same order to random presentation. As the result, we found that the acquired attractors change into the memory patterns from the correlated attractors via the the symmetrical mixed sates. |
