The generator function create the power set of the smallest frequent closed qlgorithm 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.

For mining frequent closed itemsets, all these experimental results indicate that the performances of ann algorithm are better than the traditional and typical algorithms, and it also has a good scalability. Finally, we describe the algorithm for the proposed model. Data Mining Association Analysis: A tree projection algorithm for generation of frequent itemsets.

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.

Basic Concepts and Algorithms. Discovering frequent closed itemsets for association rules. Published by Archibald Manning Modified 8 months ago. 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.
