Lesson 2 covers three major approaches for mining frequent patterns. We will learn the downward closure (or Apriori) property of frequent patterns and three major categories of methods for mining frequent patterns: the Apriori algorithm, the method that explores vertical data format, and the pattern-growth approach.

Although the size of the power-set grows exponentially in the number of items in , efficient search is possible using the downward-closure property of support (also called anti-monotonicity) which guarantees that for a frequent itemset, all its subsets are also frequent and thus no infrequent itemset can be a subset of a frequent itemset.

Definition 4 The downward closure property. Given a measure f, downward closure property, also called the admissible property , or frequency anti-monotone property , requires that for every pair of patterns p and q in the data set such that p is a subset of q 3 (p ⊆ q), the value of p computed by f is not lower than that of q, f (p) ⩾ f (q ...Cited by: 24

Downward closure property along with antimontonicity property helps to reduce the search space of possible solutions. That is, once an item set is found to be small (not a large item set), then any extension to that item set formed by adding one or more items to the set, will also yield a small item set.

We prove that the important downward closure property applies to both all-confidence and bond. We show that downward closure does not hold for any-confidence. We also prove that, if associations have a minimum all-confidence or minimum bond, then those associations will have a given lower bound on their minimum support and the rules produced
