Dunn index explained. Apr 5, 2023 · Since I explained Silhouette and Dunn Index in the post “ methods to determine the optimal number of clusters ”, I will only show their code for validation. Formula: Advantages: Another important metric is the Davies-Bouldin Index, which quantifies the average similarity ratio between clusters, offering insights into the optimal number of clusters. Dunn Index The Dunn Index evaluates the ratio of the minimum inter-cluster distance to the maximum intra-cluster distance. It then discusses the need for cluster validity indices to evaluate the quality of resulting clusters. It defines clustering as partitioning data into subsets called clusters where objects within a cluster are similar to each other and dissimilar to objects in other clusters.
