| Abstract(in English) | Shirakura and Kurata proposed a model for information separation consisting of two self-organizing maps, which are one-dimensional each and connected by plastic inhibitory connections. With inputs parametrized by two parameters the model could form a map of each parameter on each one-dimensional self-organizing map. Slightly modified for better performance but essentially a same model was examined in detail to clarify what kind of information separation is achieved by the model. Two versions of the model was numerically studied and compared. Feedforward inhibition model was shown to organize maps of PCA-like representation, while recurrent inhibition model organized ICA-like representation. |
