Cell-splitting grid: a self-creating and self-organizing neural network
A new model of self-creating and self-organizing neural network, cell-splitting grid (CSG), is presented. In this proposed CSG algorithm, the neurons and their connections are created and organized on a 2-D plane according to the input data distribution. Compared with self-organizing map (SOM) and its other improved algorithms, the CSG algorithm has outperformed SOM and other SOM-related algorithms in vector quantization while maintaining relatively good topology preservation. This paper shows that CSG is a promising and an effective method especially for non-uniformly distributed data.
