WebK-means clustering is an unsupervised machine learning tool to group similar unlabeled data or to identify patterns outside of existing categorizations in labelled data. K-means is the most widely used unsupervised machine learning tool and considered “unsupervised” due to absence of labelled data in the analysis. WebK-means clustering measures similarity using ordinary straight-line distance (Euclidean distance, in other words). It creates clusters by placing a number of points, called centroids, inside the feature-space. Each point in the dataset is assigned to the cluster of whichever centroid it's closest to.
