Suppose minsup = 0.6 and minconf = 0.7.

(a) What is the support of the itemset {b, d, e}?

(b) What is the confidence of the association rule {a} > {b, d}?

(c) Manually use the brute-force approach to find all the frequent patterns. Show all your steps.

(d) Manually use the Apriori algorithm to find all the frequent patterns. Show all your steps.

(e) Based on the above results, list all the possible association rule and determine which of them are strong.

Given the following table of transactions: TID 1 2 3 4 5 6 7 Items bought {a, b, d, e} {b, c, d] {a, b, d, e} {a, c, d, e} {b, c, d, e} {b, d, e} {c, d] {a,b,c} {a,d, e} {b, d} 8 9 10
