| Abstract(in English) | ZDDs are a data structure for combinations over item sets. They have been applied to many areas such as data mining. When ZDDs represent large-scale sparse datasets, they tend to have unbalanced form and fall into the deterioration of performance. In this paper, we propose a new data structure three-way indexing ZDD, which is a variant of ZDDs. We furthermore present conversion algorithms between three-way indexing ZDDs and usual ZDDs. Experimental results show the effectiveness of our data structure and algorithms. |
