GreyART network for data clustering

This paper attempts to incorporate grey relational analysis into the ART 2 (adaptive resonant theory) network to construct a GreyART network. GreyART networks not only possess the structure and learning ability of an ART-based network, but also use grey relational analysis to process the grey information among the data for clustering. The problems of determining the optimal number of clusters and the optimal locations of cluster centres are also considered. Additionally, the network is used to solve two data clustering problems for illustration. Simulation results demonstrate the effectiveness and feasibility of the GreyART network in solving the data clustering problems.
