WebbK-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. The "k" in "k-means" is how many centroids ...
