HYBRID BEHAVIORAL FEATURES FOR CHURN PREDICTION IN MOBILE TELECOM NETWORKS

Behavioural models help to obtain a diagnostic view of the underlying structure to predict a specific action. The importance of the role-played by social ties to better understand the underlying behaviour of customers is recognised. In this work, novel feature of the social aspects of customers’ social group along with the traditional individual customer profiles to extract hybrid behavioural novel features with potential practical implications is incorporated.

As precision plays an important role in churn prediction, one of the main ways of improving prediction performance is with the use of appropriate feature sets that have high predictive power. The prediction model built is based on features that can be extracted from Call Detail Records (CDRs) exclusively. Throughout this work no demographic or contractual information was used, regardless of the data available being restricted to only a period of one month.
