| Abstract(in English) | A new self-organizing model is studied numerically. Preceding self-organizing models of topological mappings, such as von der Malsburg's and Amari's, are based on a neural array with mexican-hat-type connection pattern. In our model, a representation layer consisting of neural units with random and symmetric, fixed connections is used instead of the neural array. The connections from an input layer to the representation layer are modified by Hebbian rule with regularization. The model assigns to an input a representation that is a firing pattern on the representation layer. It is shown that the representation preserves the distance relation between the inputs to some extent, and has finer resolution for frequent inputs. Detail relationship between input frequency and weight vector density after learning is numerically studied. |
