Apriori generates the frequent patterns by making the itemsets using pairing such as single item set, double itemset, triple itemset. FP Growth generates an FP-Tree for making frequent patterns. Apriori uses candidate generation where frequent subsets are extended one item at a time. lit stokke occasion

"Witryna18 cze 2024 · Apriori can be very fast if no items satisfy the minimum support, for example. When your longest itemsets are 2 itemsets, a quite naive version can be fine. Apriori pruning as well as the fptree only begin to shine when you go for (more interesting!) longer itemsets, which may require choosing a low support parameter. … " - Import fp_growth
