Apriori Algorithm works better with a big dataset, while the FP-Growth Algorithm works better with a small dataset [1]. One of the advantages of the apriori algorithm is easy to
WebWhat is Apriori Algorithm ? It is a classic algorithm used in data mining for finding association rules based on the principle "Any subset of a large item set must be large". It uses a generate-and-test approach – generates candidate itemsets and tests if they are frequent. Given the mininum threshold support, Generating large item sets (only ...
