Feedback Efricient Policy Feedback. 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.

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. Published by Archibald Manning Modified 8 months ago.

Data Mining Association Analysis: About project SlidePlayer Terms of Service. 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. 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.
