An itemset X is a closed itemset if there exists no itemset Y such that every transaction having X contains Y Itemwets closed itemset X is frequent if its support passes the given support threshold The concept is firstly proposed by Pasquier et al.

Finally, we describe the algorithm for the closef model. Efficiently mining long patterns from databases. Auth with social network: To use this website, you must agree to our Privacy Policyincluding cookie policy. Data Mining Association Analysis: Registration Forgot your password?

Frequent Itemset Mining Methods. 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.

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. 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.

It is suitable for mining dynamic transactions 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.
