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. …
