A Convergence Theorem for the Fuzzy ISODATA Clustering Algorithms

IEEE Transactions on Pattern Analysis and Machine Intelligence, 1980
In this paper the convergence of a class of clustering procedures, popularly known as the fuzzy ISODATA algorithms, is established. The theory of Zangwill is used to prove that arbitrary sequences generated by these (Picard iteration) procedures always terminates at a local minimum, or at worst, always contains a subsequence which converges to a local ...

On the Local Optimality of the Fuzzy Isodata Clustering Algorithm

IEEE Transactions on Pattern Analysis and Machine Intelligence, 1986
The convergence of the fuzzy ISODATA clustering algorithm was proved by Bezdek [3]. Two sets of conditions were derived and it was conjectured that they are necessary and sufficient for a local minimum point. In this paper, we address this conjecture and explore the properties of the underlying optimization problem.

Rough ISODATA Algorithm

International Journal of Fuzzy System Applications, 2013
Cluster analysis is a branch of data mining, which plays a vital role in bringing out hidden information in databases. Clustering algorithms help medical researchers in identifying the presence of natural subgroups in a data set. Different types of clustering algorithms are available in the literature. The most popular among them is k-means clustering.
