A sliding windows based dual support framework for discovering emerging trends from temporal data

Abstract: Abstract:In this paper we present the Dual Support Apriori for Temporal data (DSAT) algorithm. This is a novel technique for discovering Jumping Emerging Patterns (JEPs) from time series data using a sliding window technique. Our approach is particularly effective when performing trend analysis in order to explore the itemset variations over time. Our proposed framework is different from the previous work on JEP in that we do not rely on itemsets borders with a constrained search space. DSAT exploits previousl… Show more

“…The research described in this work also borrows from the field of Jumping and Emerging Patten (JEP) mining as first introduced by Dong and Li ( [4]). The distinction between the work on JEPs, and that described in this paper, is that JEPs are patterns whose frequency increases (typically) between two data sets (although some work has been done on identifying JEPs across multiple data sets, for example Khan et al [8]). JEP mining is usually also conducted in the context of classification (see for example [5]).…”

“…However, this concept has been recently used in (Khan et al 2010) with the purpose of obtaining a low use of memory and low proposed the use of some new operators such as rounding, repairing or filtrating. Finally, QAR have also been used in the bioinformatics field.…”

“…The frequent pattern idea has been extended in many directions. A number of authors have considered the nature of frequent patterns with respect to the temporal dimension, for example sequential patterns [8], frequent episodes [9], emerging patterns [10] and jumping and emerging patterns [3]. Many alternative frequent pattern mining algorithms, that seek to improve on Agrawal's original Apriori algorithm, have also been proposed.…”
