Description
Summary:Traditional algorithms for mining sequential patterns are built on the binary attributes databases, which have three limitations. Firstly, it can not concern quantitative attributes; secondly, only direct sequential patterns are discovered; thirdly, it can not process these data items with similar frequencies which will result in the dilemma called the rare item problem. In this paper, we put forward a discovery algorithm for mining both direct and indirect fuzzy sequential patterns with multiple minimum supports by combining these three extensions.
