What is the pruning ratio of the Apriori algorithm on this data set? (Pruning ratio is defined as the percentage of itemsets not considered to be a candidate because (1) they are not generated during candidate generation or (2) they are pruned during the candidate pruning step.)
occurring in less than 3 transactions is considered to be infrequent.
Pruning ratio is the ratio of N to the total number of itemsets. Since
the count of N = 11, therefore pruning ratio is 11/32 = 34.4%.
