| Outline of Final Research Achievements |
When we observe the faces of a person from different directions, a plurality of images are obtained, but storing these images separately is not a natural information representation. In this study, we were succeeded in storing a plurality of images as a continuous attractor, by improving the Hopfield model. The Hopfield model is one of the memory model of the brain, and is composed of the elements called the Ising spin. We found that continuous attractor occurs by extending the Ising spin to XY spin in the Hopfield model. Furthermore, even if we extend the Ising spin to the phase oscillator, it was found that the continuous attractor occurs.
