“…e algorithm finds optimal groups (clusters) of customers, transactions, or other behaviours and things with high similarities and characteristics within the clusters. Many applications of cluster analysis have been applied in various industries, such as banking [33][34][35], energy supply [36], agriculture, food [37][38][39], health and insurance [40][41][42][43], telecom [44][45][46][47][48], postal service [49,50], transportation [14,17,26,29,[51][52][53][54][55][56], and retail [38,[57][58][59][60][61][62].
