Toward a successful CRM: variable selection, sampling, and ensemble

This paper studies the effects of variable selection and class distribution on the performance of specific logit regression (i.e., a primitive classifier system) and artificial neural network (ANN; a relatively more sophisticated classifier system) implementations in a customer relationship management (CRM) setting. Finally, ensemble models are constructed by combining the predictions of multiple classifiers. This paper shows that ANN ensembles with variable selection show the most stable performance over various class distributions.
