Abstract:

For business categories of all kinds, today's advanced technologies and digital processing generates data in an unprecedented speed and volume. This rich data becomes a "gold mine" for strategic marketing teams across industries, as more and more marketers rely on advanced predictive modeling techniques to uncover actionable information for a range of critical marketing decisions. Popular modeling algorithms include decision trees, artificial neural network and traditional statistical modeling methods such as logistic regression models. During our practices of predictive modeling in the telecommunication industry, we find that a certain technique often works better with certain data types better that other, and that an ensemble model of different model types often yield better results than a single model. Moreover, we find that some continuous variables, especially those that do not follow normal distribution, often gains more predicting power when being transformed to an ordinal or nominal type through a target-supervised binning process. In this study we'll introduce the target-supervised binning process and show its improved predicting power through model performance.
