モジュール構造ニューラルネットから導出される自己想起型連想記憶モデルとその連想特性の多様性

抄録

In this paper, we propose a new autoassociative memory model which is derived from Cross-Coupled Hopfield Nets (CCHN). The CCHN is a modular neural network in which plural Hopfield networks are mutually connected via feedforward neural networks. The CCHN's architecture is determined by the following structural parameters : the number of modules, the numbers of units in the modules, the contribution of the module information processings and the interactions to the whole network information processing, and the module connectivity. If these parameters are changed, the network dynamics are also changed; therefore, it may be possible to implement a great number of autoassociative memories with different nature. Through some computer simulations, we will discuss a diversity of association properties in the proposed model.
