WebThe K-means technique is based on grouping by similarities. The algorithm performs a pre-grouping before performing the K-means groupings to avoid bad group formation since the magnitudes of consumption between these rates vary significantly. The data are normalized with Equation (2). WebStep-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. Step-4: Calculate the variance and place a new centroid of each cluster.
