Dunn index (DI) is an internal cluster validation technique. Cluster validation techniques are used for determining the goodness of a clustering algorithm. In the case of DI, the higher the value, the better the clustering result is. Dunn index is calculated by taking the ratio of the lowest inter-cluster distance and the largest intra-cluster distance from the number of clusters within the set.
