Webthe cluster validity measurement will be done in 2 ways, by Validity Measure (VM) and Davies-Bouldin Index (DBI). The validity measurement is done by forming 2 clusters to 10 clusters, then calculate the validity of each cluster. Cluster with the minimum values of DBI or VM indicates the cluster is well separated [10], it means that WebJan 24, 2013 · I'm trying to evaluate what is the right number of cluster needed for clusterize some data.
