WebThe 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. … WebK-means clustering requires us to select K, the number of clusters we want to group the data into. The elbow method lets us graph the inertia (a distance-based metric) and visualize the point at which it starts decreasing linearly. This point is referred to as the "eblow" and is a good estimate for the best value for K based on our data.
