(English Abstract)
Sequential pattern mining is an important data mining problem with broad applications. While the current methods are generating sequential patterns within a single attribute, the proposed method is able to detect them among different attributes. By incorporating these additional attributes, the sequential patterns found are richer and more informative to the user. This paper proposes a new method for generating multi-dimensional sequential patterns with the use of Hellinger entropy measure. Unlike the previously used methods, the proposed method can calculate the significance of each sequential pattern. Two theorems are proposed to reduce the computational complexity of the proposed system. The proposed method is tested on some synthesized purchase transaction databases.
