Pattern classification based on adaptive self-organizing neural network

In this paper, a character recognition system with adaptive self-organizing (AS) neural network is presented. The ASO neural tree is a tree-structured neural network which can adapt to a changing environment parametrically and structurally. The ASO neural tree grows when new concepts are learned and shrinks when old concepts are disposed. It also makes parameter adaptation to cope with small changes in the environment. The ASO neural tree is suited to hierarchical classification. When applied to character pattern recognition, it shows promising performance.
