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.

Finally, we describe the algorithm for the proposed model. Data Mining Techniques So Far: 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 frequent itemsets and association rules over them often generates a large number of frequent itemsets and rules Harm efficiency Hard to understand. And then we propose a novel model for mining frequent closed itemsets mininy on the smallest frequent closed granules, and a connection function for generating the smallest frequent closed itemsets.

An efficient algorithm for closed association rule mining. An itemset X is a closed itemset if there exists 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.

CLOSET: An Efficient Algorithm for Mining Frequent Closed Itemsets

On these different datasets, we report the performances of the algorithm and its trend of the performances to discover frequent closed itemsets, and further discuss how to solve the bottleneck of the algorithm. Contact Editors Europe, Africa: A tree projection algorithm for generation of frequent itemsets. Concepts and Techniques 2nd ed. Shahram Rahimi Muning, Australia: The generator function create the power set of the smallest frequent closed itemsets in the enlarged frequent 1-item manner, which can efficiently avoid generating an undesirably large set of candidate smallest frequent closed itemsets to reduce the costed CPU and the occupied main memory for generating the smallest frequent closed granules.
