Suppose the support threshold is 5. Find the maximal frequent item sets for the data of:

(a) Exercise 6.1.1.

(b) Exercise 6.1.3.

Exercise 6.1.1

Suppose there are 100 items, numbered 1 to 100, and also 100 baskets, also numbered 1 to 100. Item i is in basket b if and only if i divides b with no remainder. Thus, item 1 is in all the baskets, item 2 is in all fifty of the even-numbered baskets, and so on. Basket 12 consists of items {1, 2, 3, 4, 6, 12}, since these are all the integers that divide 12. Answer the following questions:

(a) If the support threshold is 5, which items are frequent?

(b) If the support threshold is 5, which pairs of items are frequent?

Exercise 6.1.3

Suppose there are 100 items, numbered 1 to 100, and also 100 baskets, also numbered 1 to 100. Item i is in basket b if and only if b divides i with no remainder. For example, basket 12 consists of items
