Consider the database shown in Table 7.14. What are the support and confidence values for the following negative association rules involving regular and diet soda?
The original association rule mining framework considers only presence of items together in the same transaction. There are situations in which itemsets that are infrequent may also be informative. For instance, the itemset TV, DVD, ¬ VCR suggests that many customers who buy TVs and DVDs do not buy VCRs. In this problem, you are asked to extend the association rule framework to negative itemsets (i.e., itemsets that contain both presence and absence of items). We will use the negation symbol (¬) to refer to absence of items. i. ¬Regular ?? Diet. ii. Regular ?? ¬Diet. ii. Regular ?? ¬Diet. iv. Diet ?? ¬Regular.
