Step 2: Assign each data point to the nearest centroid. The commonly used distance calculation for K-Means clustering is the Euclidean Distance, a scale value that measures the distance between two data points. Step 3: Update cluster centroids.

WebWe will have to use the minimum of these distances as the inter-cluster separation. \( \Delta_k \) is the intra-cluster distance of cluster \( x_k \), i.e., the distance within the cluster \( x_k \), which involves computing the distance between every data point to every other data point in the same cluster. WebDunn Index = (minimum distance between two clusters)/(maximum distance of points within the cluster) So basically, this is the distance between two clusters divided by inertia . The … WebDec 1, 2024 · At k = k * + 1, k-Means will place two centers in the same cluster, leading to a minimum inter-center distance that is less that d/2.
