Apply Toivonen’s Algorithm to the data of  6.3.1, with a support threshold of 4. Take as the sample the first row of baskets: {1, 2, 3}, {2, 3, 4}, {3, 4, 5}, and {4, 5, 6}, i.e., one-third of the file. Our scaleddown support theshold will be 1. (a) What are the itemsets frequent in the sample? (b) What is the negative border? (c) What is the outcome of the pass through the full dataset? Are any of the itemsets in the negative border frequent in the whole?
