arules- A Computational Environment for Mining Association Rules and Frequent Item Sets

Abstract: Mining frequent itemsets and association rules is a popular and well researched approach for discovering interesting relationships between variables in large databases. The R package arules presented in this paper provides a basic infrastructure for creating and manipulating input data sets and for analyzing the resulting itemsets and rules. The package also includes interfaces to two fast mining algorithms, the popular C implementations of Apriori and Eclat by Christian Borgelt. These algorithms can be used t… Show more

“…Rule generation was performed on discretized data using the arules package ( [16], v1.0-14), with minimal support = 0.001, confidence = 0.001, and a rule size of two. A two-item rule size was necessitated by the NHANES study design as not every environmental exposure was measured in each subject.…”

“…The apriori algorithm [6,8,16] is a breadth-first search of an itemset that can be used to identify association rules describing the implication between the item(s) on the left-hand side (LHS, antecedent) and those on the right-hand side (RHS, consequent). Association rules have been used to mine medical records data to identify potential correlations from frequent co-occurring features, for example incidence of a side effect and a prescribed drug [9,17,22,21,25].…”

“…See Hahsler et al (2005) for a more recent discussion of mining of association rules and a computer package providing tools. The problem of predicting the next step in a journey conditional on the observed history is also much studied, but is not relevant here.…”

“…2) Difference of Confidence (DOC) [7] This correlation measure is to compare the posterior and the prior confidence of an association rule [6]. Since the former should differ considerably from the latter to make the rule interesting, which means the occurrence of A has a significant impact on the occurrence of B.…”
