Inter cluster distance
WebDec 10, 2024 · Here comes the concept of inter and intra cluster distance. Intra cluster distance is handled by inertia, and that is the distance between the data points which are inside one cluster. Inter cluster distance means the distance between 2 different clusters.

WebJun 2, 2024 · Inter-cluster distance is the distance between the data items in distinct clusters. The inter-cluster distance can be defined in one of the following ways: (a) Between the cluster centroids, (b) between the closest items, (c) between the farthest items, (d) the average distance between all the items in distinct clusters [ 8 ].
The inter-cluster distance d(i,j) between two clusters may be any number of distance measures, such as the distance between the centroids of the clusters. Similarly, the intra-cluster distance d '( k ) may be measured in a variety ways, such as the maximal distance between any pair of elements in cluster k .
