K-means algorithm – A clear and easy explanation of Kmeans

A clear and plain English explanation of Kmeans! The K-means algorithm starts by placing K points (centroids) at random locations in space. We then perform the following steps iteratively: (1) for each instance, we assign it to a cluster with the nearest centroid, and (2) we move each centroid to the mean of the instances assigned to it.
