Assume that the support threshold is equal to 30%.
Given the lattice structure shown in Figure 6.4 and the transactions given in
Table 6.3, label each node with the following letter(s):
• M if the node is a maximal frequent itemset,
• C if it is a closed frequent itemset,
• N if it is frequent but neither maximal nor closed, and
• I if it is infrequent.
The lattice structure is shown below.
