Problem 6. (16 points) Here is a collection of twelve baskets. Each contains three of the six items 1 through 6. {1,2,3} {2,3,4} {3,4,5} {4,5,6} {1,3,5} {2,4,6} {1,3,4} {1,3,4} {2,4,5) {3,5,6} {1,2,4} {2,3,5} {3,4,6} Suppose the support threshold is 4. On the first pass of the PCY Algorithm we use a hash table with 11 buckets, and the set {1,j} is hashed to bucket ixj mod 11. (a) By any method, compute the support for each item and each pair of items. (b) Which pairs hash to which buckets? (c) Which buckets are frequent? (c) Which pairs are counted on the second pass of the PCY Algorithm? Problem 6. (16 points) Here is a collection of twelve baskets.
