    • Sequence Mining - an overview ScienceDirect Topics

    Over the past decade, a number of sequence mining methods have been proposed that handle the exponential search by using various heuristics. The first sequence mining algorithm was called GSP [3], which was based on the a priori approach for mining frequent itemsets [2]. GSP makes several passes over the database to count the support of each sequence and to generate candidates.

An item can occur at most once in an event of a sequence, but can occur multiple times in different events of a sequence. The number of instances of items in a sequence is called the length of the sequence. A sequence with length l is called an l-sequence. A sequence α = ha 1a 2a

    • A Survey on Frequent Pattern Mining Techniques in

    2016-8-11  Sequential pattern mining is find the relationships between occurrences of sequential events for looking for any specific order of the occurrences. In the other words, sequential pattern mining aims at finding the frequently occurred sequences to analyse the data or predict future data or mining periodical patterns. It uses support as the criteria to evaluate frequency but is not efficient to discover some patterns. The problem of mining sequential pattern can be partitioned into three categories: periodic patterns, statistically patterns, and approximate patterns. In this paper we will discuss a few approximate pattern mining techniques
