CLOSET: An Efficient Algorithm for Mining Frequent Closed Itemsets

Mining frequent patterns without candidate generation. Efficiently mining long patterns from databases. Data Mining Techniques So Far: Feedback Privacy Policy Feedback. Finally, we describe the algorithm for the proposed model. Efficient algorithms for discovering association rules. Data Mining Association Analysis: 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.

Registration Forgot your password? Mining frequent itemsets and association rules over them often generates a large number of frequent itemsets and rules Harm efficiency Hard to understand.

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

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.
