An Improved Multi-SOM Algorithm for Determining the Optimal Number of Clusters

A new approach for improving clustering algorithms performance

“…Zhou et al [17] propose a method to determine the optimal number of clusters based on an agglomerative hierarchical clustering algorithm and a new clustering validity index to evaluate the results produced by the method. Khanchouch, et al [18] focus on multi-SOM clustering algorithm and test this algorithm using real data sets with two evalution criteria to extract the optimal number of clusters. This method takes less iterations steps but considered insufficient to define the boundaries of each cluster.…”
