Temporal Sequential Pattern in Data Mining Tasks
The rapid increase in the data available leads to the difficulty for analyzing those data and different types of frameworks are required for unearthing useful knowledge that can be extracted from such databases. The field of temporal data mining is relatively young and one expects to see many new developments in the near future. In all data mining applications, the primary constraint is the lar...
متن کاملSurvey of Sequential Pattern Mining Algorithms and an Extension to Time Interval Based Mining Algorithm
Sequential pattern mining finds the subsequence and frequent relevant patterns from the given sequences. Sequential pattern mining is used in various domains such as medical treatments, natural disasters, customer shopping sequences, DNA sequences and gene structures. Various sequential pattern mining algorithms such as GSP, SPADE, SPAM and PrefixSpan have been proposed for finding the relevant...
متن کاملTemporal Support in Sequential Pattern Mining
In sequential pattern discovery, the support of a sequence is computed as the number of data-sequences satisfying a pattern with respect to the total number of data-sequences in the database. When the items are frequently updated, the traditional way of counting support in sequential pattern mining may lead to incorrect (or, at least incomplete), conclusions. For example, if we are looking for ...
متن کاملTime-Constrained Sequential Pattern Mining
Sequential pattern mining is one of the important issues in the research of data mining (Agrawal & Srikant, 1995; Ayres, Gehrke, & Yiu, 2002; Han, Pei, & Yan, 2004; Lin & Lee, 2004; Lin & Lee, 2005b; Roddick & Spiliopoulou, 2002). A typical example is a retail database where each record corresponds to a customer’s purchasing sequence, called data sequence. A data sequence is composed of all the...
متن کاملFrequency-Based Temporal Pattern Mining in Health Data
The low occurrence rate of adverse drug reactions makes it difficult to identify the risk factors from straightforward application of frequent pattern discovery in large databases. In this paper, we are interested in developing a data mining strategy that can fully utilize the information around rare events in sequence data in order to measure the multiple occurrences of patterns in the whole p...
