چکیده

In incremental databases, new transactions will add continuously to the old transactions. Maximal frequent patterns are one of the condensed representations of frequent patterns. Recently, regular pattern mining along with frequent patterns playing an important role in data mining research. Several algorithms have been proposed so far to mine maximal frequent patterns on various domains. There is no suitable algorithm to mine maximal regular frequent (MRF) itemsets in incremental databases using transaction_ids. So, in this paper we are proposing a new algorithm called IncMaRFI to mine MRF itesmsets in incremental databases using common items from a set of transaction_id pairs. Our algorithm extracts all the latest MRF itemset(s) at a time with in a single scan. Our experiment results show the out performance of our algorithm.

A comprehensive method for discovering the maximal frequent set

The association rule mining can be divided into two steps.The first step is to find out all frequent itemsets, whose occurrences are greater than or equal to the user-specified threshold.The second step is to generate reliable association rules based on all frequent itemsets found in the first step. Identifying all frequent itemsets in a large database dominates the overall performance in the a...

Incremental Techniques for Mining Dynamic and Distributed Databases

Traditional methods for data mining typically make the assumptions that the data is centralized and static. These assumptions are no longer tenable. Such methods impose excessive communication overhead when data is distributed. Also, they waste computational and I/O resources when data is dynamic. In this paper we present what we believe to be the first data mining approach that overcomes all t...

Mining Frequent Itemsets in Distributed and Dynamic Databases

Traditional methods for frequent itemset mining typically assume that data is centralized and static. Such methods impose excessive communication overhead when data is distributed, and they waste computational resources when data is dynamic. In this paper we present what we believe to be the first unified approach that overcomes these assumptions. Our approach makes use of parallel and incremen...
