This questiоn is frоm the tоpic of Rаnd Index computаtion for compаring clusterings. Consider that clustering algorithm-1 produces three clusters from data as follows: Cluster1 (A B C), Cluster2 (E F), and Cluster3 (G H) And clustering algorithm-2 produces two clusters from the same data, as follows: Cluster1(A B C E) and Cluster2 (F G H) Answer the following: (a) How many point pairs belong to the same cluster in both clusterings? Show an example point-pair that belongs to the same cluster in both clusterings. (b) How many point pairs are placed in different clusters by algorithm-1 and also by algorithm-2? Show an example point-pair with such behavior. (c) How many point pairs are placed in the same same cluster by algorithm-1 but in different clusters by algorithm-2? Show an example point pair with such behavior. (d) How many point pairs are placed in the same same cluster by algorithm-2 but in different clusters by algorithm-1? Show an example point pair with such behavior. (e) What is the RAND index for similarity between the clusterings obtained by algorithm-1 and algorithm-2?
