Fuzzy c-means (FCM) is a simple but powerful clustering method using the concept of fuzzy sets that have been proved to be useful in many areas. There are, however, several well-known problems with FCM, such as sensitivity to initialization, sensitivity to outliers, and limitation to convex clusters. In this paper, a new clustering method, which is an extension of global fuzzy c-means (G-FCM) and kernel fuzzy c-means (K-FCM), is proposed to resolve the shortcomings mentioned above. G-FCM is a variant of FCM that uses an incremental seed selection method and is effective in alleviating the sensitivity to initialization. There are several approaches to reduce the influence of noise and properly partition non-convex clusters and K-FCM is one of them. K-FCM is used in this paper because it can easily be extended with different kernels, which provide sufficient flexibility to allow for resolution of the shortcomings of FCM. By combining G-FCM and K-FCM, the proposed method, kernelized global FCM (KG-FCM), can resolve the shortcomings mentioned above. The usefulness of KG-FCM is demonstrated by experiments using artificial and real world data sets.
