Microarray
technology has made it possible to simultaneously measure the expression levels
of large numbers of genes in a short time. For the analysis of microarray data,
clustering techniques are frequently used. So in this study, in cases where
classical clustering analysis is insufficient to analyze data, fuzzy c-means
algorithm and Gustafson-Kessel algorithm, which are improved to supply with
advancing alternative statistical methods, are used. Firstly, the number of the
optimum cluster was decided since the number of the cluster was not known at
the beginning. Then, validity indexes and elbow criterion are applied to find
the optimal number of clusters for both algorithms. It is seen that for both
algorithms, the elbow was situated in the c=3 position as a result of the
experimental result. At the end of the study, it is graphically stated that the
fuzzy c-means algorithm is getting better clusters for the colon cancer dataset.
