| Abstract | Empirical studies which has used data mining (DM) techniques has tried to assess the importance of one model over the other based on confusion-matrix-derived parameters of prediction accuracy, lift charts or receiver operating characteristic curve (ROC). A different approach of comparison based on evaluation composite indicators (ECI) has been adopted by references [2] and [3]. Study [3] has used four different input variable selection alternatives (IVSA) (original, aggregated, principal components, and stacking based variables) for a customer churn problem and has used comparison criteria (parameters) like accuracy, interpretability, robustness, and speed. Study [2] has used the same results for these four criteria along-with a newly defined fifth criteria which has been named as residual efficiency (RE) and is based on the idea of characteristics of interest (COI) of for classifiers [19]. Both studies [3] and [2] have compared five predictive classifiers but using different weighting methods and normalization techniques. Study [3] has used three weighting criteria (equal weights and two randomly assigned unequal weights) along with two normalization methods (z-score and min-max) and study [2] has used analytical hierarchy process (AHP) as weighting criteria along with a step wise utility functions (SWUF) of [18] as normalization technique. This article has used AHP weights which are normalized with a new continuous-band utility function (CBUF) used by [5] and min-max (for comparison). Finally, comparison of the results from all these studies has been presented. |
