From January 1, 2019, new amendments to the Tax Code of Azerbaijan entered into force, according to which, small- and medium-sized businesses received various benefits, with clusters being one of them.

Criteria for members of SME clusters to be defined in Azerbaijan
Separation Index (SI) is another cluster validity measure that utilizes cluster centroids to measure the distance between clusters, as well as between points in a cluster to their respective cluster centroid.
It is defined as the ratio of average within-cluster variance to the square of the minimum pairwise distance between clusters:
High dimensional data partitioning with an adaptive ensemble construction and analysis scheme
The KL index produces the traces of the within-clusters matrices for two consecutive clusters, and the higher the KL index, the better the cluster results [30].
WK is the sum of all point-to-point distances of observations within each cluster, summed across all clusters.
K-Means Cluster for Seismicity Partitioning and Geological Structure Interpretation, with Application to the Yongshaba Mine (China)
Partitioning methods [8] aim to organize data into a number of distinct clusters, such that the total deviation of the data points from the cluster centers is minimized.
Some methods adjust the clustering result by modifying the parameters of the clustering algorithm, such as the number of target clusters and the density or distance threshold for partitioning the clusters as well as the weights of each attribute when computing the similarity between each data point.
