CLOSET: An Efficient Algorithm for Mining Frequent Closed Itemsets

Registration Forgot your password? Mining frequent patterns without candidate generation. Support Informatica is supported by: 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.

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.

Frequent Itemset Mining Methods. 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.

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 cloded costed CPU and the occupied main memory for generating the smallest frequent closed granules. A tree projection algorithm for generation of frequent itemsets. Concepts and Techniques 2nd ed.

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.
