An Efficient Algorithm for Mining Frequent Closed Itemsets | Fang | Informatica

Published by Archibald Manning Modified 8 months ago. An itemset X is a closed itemset if there floset no itemset Y such that every transaction having X contains Y A closed itemset X is frequent if its support passes the given support threshold The concept is firstly proposed by Pasquier et al.

Informatica is financially supported by the Slovenian research agency from the Call for co-financing of scientific periodical publications. Abstract To avoid generating an undesirably large set of frequent itemsets for discovering all high confidence association rules, the problem of finding frequent closed itemsets in a formal mining context is proposed.

Mining association rules from large datasets.

In this paper, aiming to these shortcomings of typical algorithms for mining frequent closed itemsets, such as the algorithm A-close and CLOSET, we propose an efficient algorithm for mining frequent closed itemsets, which is based on Galois connection and granular computing.
