    Itemsets that meet a minimum support threshold are referred to as frequent itemsets. The rationale behind the use of support is that a retail organization is only interested in those itemsets that occur frequently. However, the support of an itemset tells only the number of transactions in which the itemset was purchased.

    The data set that will produce frequent itemsets with highest maximum support is data set (b). (e) Which data set(s) will produce frequent itemsets containing items with wide-varying support levels (i.e. items with mixed support, ranging fromr less than 20% to more than 70%).

    6.1.1 Definition of Frequent Itemsets Intuitively, a set of items that appears in many baskets is said to be “frequent.” To be formal, we assume there is a number s, called the support threshold. If I is a set of items, the support for I is the number of baskets for which I is a subset. We say I is frequent if its support is sor more.

    Apr 19, 2019 · a. Given a transaction database and different minimum input support’s (MIS) for each item and confidence, find all the rules 𝑋 → 𝑌 that satisfy the given support and confidence constraints. b. A support is a threshold that would determine if the items in X are frequent enough to be considered for association rule generation.

    early without having to compute their support and confidence values. An initial step toward improving the performance of association rule min-ing algorithms is to decouple the support and confidence requirements. From Equation 6.2, notice that the support of a rule X −→ Y depends only on the support of its corresponding itemset, X ∪ Y.
