Recently, an efficient method has been proposed to use Zero-suppressed Binary Decision Diagrams \linebreak (ZBDDs) for extracting and representing a huge amount of frequent itemsets in data mining. In general, it is well-known that the size of ZBDDs greatly depend on variable ordering, however, in the specific cases of applying ZBDDs to data mining, the effect of variable ordering has not been understood well. In this paper, we show two typical database examples we found out, where the ZBDD size is exponentially sensitive to variable ordering. We discuss why they are so sensitive. |
