The rule A ⇒ B holds in the data set (transactions) D with supports, where ‘s’ is the percentage of transactions in D that contain A ∪ B (i.e., the union of set A and set B, or both A and B). This is taken as the probability, P (A ∪ B).Single linkage clustering involves visualizing data, calculating a distance matrix, and forming clusters based on the shortest distances. After each cluster formation, the distance matrix is updated to reflect new distances. This iterative process continues until all data points are clustered, revealing patterns in the data.
