Abstract: Kernel k-means clustering can correctly identify and extract a far more varied collection of cluster structures than the linear k-means clustering.Kernel-based clustering algorithm can identify and capture the non-linear structure in datasets, and thereby it can achieve better performance.There have been many clustering algorithms, such as k-means (KM) and its variants [1–16]. Others are based on minimal spanning trees [17–19].incorporation of kernel function enables the K-Means algorithm to explore the. K-. Means algorithm aims to partition the N samples into K clusters, 1.Also, we can see that the proposed algorithm is readily extendable to develop better clustering algorithms by designing the matrix-induced regularization.Kernel ClusteringScalable Kernel K-Means Clustering with Nystrom. - arXivThe global kernel k-means clustering algorithm - IEEE Xplore. juhD453gf
