Abstract

We consider the problem of finding association rules ina database with binary attributes. Most algorithms for findingsuch rules assume that all the data is available at the start ofthe data mining session. In practice, the data in the databasemay change over time, with records being added and deleted. Atany given time, the rules for the current set of data are of interest. The naive, and highly inefficient, solution would be torerun the association generation algorithm from scratch followingthe arrival of each new batch of data. This paper describes theBorders algorithm, which provides an efficient method forgenerating associations incrementally, from dynamically changingdatabases. Experimental results show an improved performance ofthe new algorithm when compared with previous solutions to theproblem.
