A 2-itemset whose corresponding bucket count in the hash table is below the support. Mining Frequent Itemsets without Candidate Generation. As we have seen, in many cases the Apriori candidate generate-and-test method significantly reduces the size of candidate sets, leading to good performance gain. However, it can suffer from two nontrivial ...

a worthwhile effort to seek the most efficient techniques to solve this task. The Apriori algorithm Together with the introduction of the frequent set mining problem, also the first algorithm to solve it was proposed, later denoted as AIS. Shortly after that the algorithm was improved by R. Agrawal and R. Srikant and called Apriori.

Jan 14, 2022 Frequent itemset mining (FIM) is a common approach for discovering hidden frequent patterns from transactional databases used in prediction, association rules, classification, etc. Apriori is an FIM elementary algorithm with iterative nature used to find the frequent itemsets. Apriori is used to scan the dataset multiple times to generate big frequent
