Facilitating cross-selling in a mobile telecom market to develop customer classification model based on hybrid data mining techniques

► In this study, we propose a customer classification model. ► The model may be used for facilitating cross-selling in a mobile telecom market. ► The various data mining techniques are applied to our proposed model in two steps. ► In the first step, our model predicts the purchase of new products. ► In the second step, our model compromises prediction probabilities by using GA.
