, APRIORI-SD: Adapting Association Rule
Learning to Subgroup Discovery

{branko.kavsek,nada.lavrac,}
Abstract. This paper presents a subgroup discovery algorithm
APRIORI-SD, developed by adapting association rule learning to sub-
group discovery. This was achieved by building a classification rule
learner APRIORI-C, enhanced with a novel post-processing mechanism,
a new quality measure for induced rules (weighted relative accuracy) and
using probabilistic classification of instances. Results of APRIORI-SD
are similar to the subgroup discovery algorithm CN2-SD while experi-
mental comparisons with CN2, RIPPER and APRIORI-C demonstrate
that the subgroup discovery algorithm APRIORI-SD produces substan-
tially smaller rule sets, where individual rules have higher coverage and
significance.
1 Introduction
Classical rule learning algorithms are designed to construct classification and
prediction rules [12,3,4,7]. In addition to this area of machine learning, referred
to as supervised learning or predictive induction, developments in descriptive
induction have recently gained much attention, in particular association rule
learning [1] (e.g., the APRIORI association rule learning algorithm), subgroup
discovery (e.g., the MIDOS subgroup discovery algorithm [18,5]), and other
approaches to non-classificatory induction.
As in the MIDOS approach, a subgroup discovery task can be defined as
follows: given a population of individuals and a property of those individuals
we are interested in, find population subgroups that are statistically ‘most in-
teresting’, e.g., are as large as possible and have the most unusual statistical
(distributional) characteristics with respect to the property of interest [18,5].
Some of the questions on how to adapt classical classification rule learning
approaches to subgroup discovery have already been addressed in [10] and a
well-known rule learning algorithm CN2 was adapted to subgroup discovery. In
this paper we take a rule learner APRIORI-C instead of CN2 and adapt it to
subgroup discovery, following the guidelines from [10].
We have implemented the new subgroup discovery algorithm APRIORI-SD
in C++ by modifying the APRIORI-C algorithm. The proposed approach per-
forms subgroup discovery through the following modifications of the rule learning
algorithm APRIORI-C: (a) using a weighting scheme in rule post-processing, (b)
using weighted relative accuracy as a new measure of the quality of the rules in
