| Research Abstract |
This investigation deals with classification problems, such as diagnosis, in which classes are defined by categorical forms. Recently, soft computing techniques including learning algorithm in neural networks and fuzzy expert systems are applied to the classification problems. We have already presented a prototype of associative classification model using cellular neural networks(CNN). That is categories or classes are expressed by bitmap patterns consist of pixels which have three levels. Classification is done by association from the given data expressed by bitmap pattern. The problem is, firstly, which associative memory is suit for this classification method. We investigate two kind of associative memories, one is the associatron, and the other is extended CNN.The associatron is a model for a neural network proposed by Nakano. It embeds Hebb's law using a method to strengthen the synapse connection that interprets that the synapse connection between simultaneously excited cells grows stronger. Associative classification using associatron yields an outstanding result in the problem of iris. On the contrary, extended CNN shows remakable effects for diagnosing of liver disease.
