K-means clustering definition
WebK-means clustering is a simple and elegant approach for partitioning a data set into K distinct, nonoverlapping clusters. To perform K-means clustering, we must first specify … WebThis definition of Euclidean distance, therefore, requires that all variables used to determine clustering using k-means must be continuous. Procedure. In order to perform k-means clustering, the algorithm randomly assigns k initial centers (k specified by the user), either by randomly choosing points in the “Euclidean space” defined by all ...
