NettetThe k-means clustering algorithm. K-means clustering is a prototype-based, partitional clustering technique that attempts to ﬁnd a user-speciﬁed number of clusters (k), which are represented by their centroids. Procedure. We ﬁrst choose k initial centroids, where k is a user-speciﬁed parameter; namely, the number of clusters desired. NettetThe working of the K-Means algorithm is explained in the below steps: Step-1: Select the number K to decide the number of clusters. Step-2: Select random K points or centroids. (It can be other from the input dataset). Step-3: Assign each data point to their closest centroid, which will form the predefined K clusters.
