Modified Sequential Pattern Mining Using Direct Bit Position Method

Dr. K. Subramanian, E. Elakkiya

Abstract: A new algorithm for mining sequential patterns was proposed in this paper. The proposed algorithm employs efficient direct bit position manipulations techniques for mining sequential data with long sequences. The prominent feature of the proposed algorithm DBP-SPAM is that the frequent item sets are discovered by bit position pruning technique and the experimental evaluation showcased that the proposed algorithm outperforms the previous algorithms up to an order of magnitude in terms of execution speed and memory footprints.
