Title: Does Pruning Association Rules Make Sense?
Author(s): Andreas Schloegl*+ and Rene Keller
Companies: Student and Universität Augsburg
Address: Am Gerstenfeld 7, Friedberg, 86316, Germany
Keywords: association rules ; visualization ; Pruning methods
Abstract:

Pruning association rules is a common and competitive task. Even small datasets can lead to a very large number of calculated rules. This article shows why pruning methods are useful. Several methods have been discussed in the literature, but their behavior has only been shown on small datasets. The most common application for association rules is market basket data. These datasets are potentially very large, so it is valuable to analyZe the use of these pruning methods for such data. Graphical displays implemented in our software PISSARRO help to understand how these procedures work. The use of PISSARRO allows us to combine theoretical ideas and practical applications.
