“…Apriori algorithm is one of the most classic association rule mining algorithms, which was proposed by American scholar R. Agrawal. e Apriori algorithm consists of two main steps, the first step is to obtain the set of frequent items from the transaction records; the second step is to obtain the association rules based on the set of frequent items [5]. e Apriori algorithm is not without drawbacks, it has multiple iterations of recording things, resulting in I/O that cannot be done quickly, and can create multiple candidates sets as well as the problem of too frequent itemsets, which can make this algorithm less useful.…”
