Mining Frequent Closed Itemsets from Distributed Dataset
2008 International Symposium on Computational Intelligence and Design, 2008In this paper we address the problem of mining frequent closed itemsets in a highly distributed setting. The extraction of distributed frequent (close) itemsets is an important task in data mining. The paper shows how frequent closed itemsets, mined independently in each site, can be merged in order to derive globally frequent closed itemsets ...

An Algorithm for Mining Lower Closed Itemsets
2004The generalized association rule base(GARB) presented by Li(2003) can efficiently solve the problem of quantity of rule in the process of acquiring rule by traditional association rule mining algorithms. Therefore, how to deduce all rules contained in the rule of GARB becomes an urgent issue in order to support more effective decision-making.

Mining Frequent Closed Itemsets for Association Rules
2009Association refers to correlations that exist among data. Association Rule Mining (ARM) is an important data-mining task. It refers to discovery of rules between different sets of attributes/items in very large databases (Agrawal R. & Srikant R. 1994). The discovered rules help in strategic decision making in both commercial and scientific domains.

Closed Itemset Mining and Non-redundant Association Rule Mining
2009DEFINITION Let I be a set of binary-valued attributes, called items. A set X ⊆ I is called an itemset. A transaction database D is a multiset of itemsets, where each itemset, called a transaction, has a unique identifier, called a tid. The support of an itemset X in a dataset D, denoted sup(X), is the fraction of transactions in D where X appears as a ...

LSCMiner: Efficient Low Support Closed Itemsets Mining
2019Itemsets with relatively low support values are important since they usually suggest highly confident association rules, which are useful in applications such as recommendation systems and medical data analysis. However, most existing algorithms are mainly designed to mine frequent patterns and thus are time consuming in generating low support patterns.

Mining Frequent Closed Itemsets Without Candidate Generation
2005Mining frequent closed itemsets provides complete and non-redundant result for the analysis of frequent pattern. Most of the previous studies adopted the FP-tree based conditional FP-tree generation and candidate itemsets generation-and-test approaches.
