2. A Recursive Algorithm for Mining Association Rules

Author

Subjects
Computer Science - Databases, Mathematics - Statistics Theory
Abstract

Mining frequent itemsets and association rules is an essential task within data mining and data analysis. In this paper, we introduce PrefRec, a recursive algorithm for finding frequent itemsets and association rules. Its main advantage is its recursiveness with respect to the items. It is particularly efficient for updating the mining process when new items are added to the database or when some are excluded. We present in a complete way the logic of the algorithm, and give some of its applications. After that, we carry out an experimental study on the effectiveness of PrefRec. We first compare the execution times with some very popular frequent itemset mining algorithms. Then, we do experiments to test the updating capabilities of our algorithm.

In this paper, we introduce PrefRec, a recursive algorithm for finding frequent itemsets and associationrules. Its main advantage is its recursiveness with respect to the items. Itis particularly efficient for updating the mining process when new itemsare added to the database or when some are excluded. We present in acomplete way the logic of the algorithm as well as its various applications.Finally we present experiments carried out in the R language comparingPrefRec with Apriori and Eclat the two most powerful algorithms in thislanguage. To achieve this we built an R package to run our algorithm.
