Question 1 [15 marks] Suppose that we have five items (a, b,c, d,e), and we are only given information on the first four items in the table below. Itemset | Frequency {a} 17 {b} 10 {c} 13 {d} 7 {a, b} 6 {b, c} 2 {b, d} 7 Using a support threshold s = 5, categorize the following itemsets into guaranteed to be frequent, guaran- teed to be infrequent or not enough information to decide. Please give your answer by marking exactly one tick (VW) in each row of the table below. Itemset | guaranteed to be frequent | guaranteed to be infrequent | not enough information to decide {a,c} | | | {c, d} | {b,d,e} | | {b, c, d} {a, b, c, d}
