On the Statistical Comparison of Inductive Learning Methods
Experimental comparisons between statistical and machine learning methods appear with increasing frequency in the literature. However, there does not seem to be a consensus on how such a comparison is performed in a methodologically sound way. Especially the effect of testing multiple hypotheses on the probability of producing a ”false alarm” is often ignored.
We transfer multiple comparison procedures from the statistical literature to the type of study discussed in this paper. These testing procedures take the number of tests performed into account, thereby controlling the probability of generating ”false alarms”. The multiple comparison procedures selected are illustrated on well-know regression and classification data sets.
