Experimental Comparison of Three Subgroup Discovery Algorithms: Analysing Brain Ishaemia data

The paper presents experimental results of subgroup discovery algorithms SD, CN2-SD and Apriori-SD implemented in the Orange data mining software. The experimental comparison shows that algorithms perform quite differently on data discretized in different ways. From the experiments, performed in the brain ischaemia domain, it is impossible to conclude which discretization is the most adequate for subgroup discovery.
