For mining frequent closed itemsets, all these experimental results indicate that the performances of the algorithm are better than the traditional and typical algorithms, and it also has a good scalability. Informatica is financially supported by the Slovenian research agency from the Call for co-financing of scientific periodical publications.

Shahram Rahimi Asia, Australia: Registration Forgot your password? And then we propose a novel model for mining frequent closed itemsets based on the smallest frequent closed granules, and a connection function for generating the smallest frequent closed itemsets. It is suitable for mining dynamic transactions datasets. Efficient algorithms for discovering association rules. 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.
Mining frequent patterns without candidate generation. 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.

Discovering frequent closed itemsets for association rules. Support Informatica is supported by: Data Mining Techniques So Far: Contact Editors Europe, Africa: Finally, we describe the algorithm for the proposed model. 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.

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.

CLOSET: An Efficient Algorithm for Mining Frequent Closed Itemsets
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.
