Detailed Description

This class implements the centroid clustering algorithm presented in "Clustering by Competitive Agglomeration" from Frigui and Krishnapuram, Pattern Recognition, Vol.

30, No. 7, pp. 1109-1119, 1997. The algorithm is a fuzzy clustering algorithm, which reduces a given partition to an optimal number of clusters. Here, the initial partition is generated by first performing a fuzzy-C-Means run on the data. Note: since the number of clusters will only be decreased by this algorithm, the fuzzy-C-Means parameters should be modified such that the number of clusters is chosen to be much larger than the expected number of clusters.
