Abstract(in English) | In this study, we analyze the structure of attractors in associative memory model of XY-spin system. We also study the change of the structure of attractors when the correlation between the memory patterns is changed. Since we focus to the structure of attractors, the number of memory patterns is limited to finite number(p = 3). As the result, it has been understood that each memory pattern is acquired as not a point attractor but a continuous (line) attractor for which the free energy on the route from a certain memory pattern to another memory pattern is a shape of valley. It is thought that such the continuous attractor is important findings to determine the brain mechanisms because a lot of firing patterns like the continuous attractor are found in the brain. |
