“…K-means is one of the most widely used partition-based clustering algorith ms in practice. It is simp le, easy, understandable, scalable, and can be adapted to deal with streaming data and very large datasets [20]. Kmeans algorith m d ivides a dataset X into k disjoint clusters based on the dissimilarities between data objects and cluster centroids.…”

“…Clustering is a process of partitioning or grouping a set of data objects into a number of clusters such that similar patterns are assigned to one cluster [24]. K-means clustering is one of the simplest unsupervised learning algorithms that solve the well-known clustering problem.…”
