Show two rules that have a confidence of 0.7 or greater for an itemset containing three items from Exercise 28.14.
What will be an ideal response?
There is only one frequent itemset of size 3, i.e., {milk,bread,eggs}. We can try the rule milk,eggs -> bread. The confidence of this rule is 0.3/0.3 which exceeds the min confidence value of 0.7. Another rule we can try is bread -> milk,eggs. The confidence of this rule is 0.3/0.4 which again satisfies the min confidence requirement.
