O) (B, G, K, NZ) (B, G, N, T, Z) (a) What is the maximum number of possible frequent itemsets given that this data set has 5 items per transaction? (b) Find all frequent itemsets using the Apriori algorithm. Enter each value in alphabetical order with a comma separating each (no spaces). E.g.. AB,AC,BC,BD If there are none, put the word NONE. This is auto-graded so follow instuctions exactly including upper-cose, no spoces, commos, etc All the frequent 1-itemsets: t All the frequent 2-itemsets: All the frequent 3-itemsets: All the frequent 4-itemsets: t All the frequent 5-itemsets: (c) In the computation above, how many rounds of database scans are needed?
