A Mixed Process Neural Network and its Application to Churn Prediction in Mobile Communications
Hong Kong(2006)
Abstract
Churn prediction is an increasingly pressing issue in today's ever-competitive commercial environments, especially in mobile communication arena. In this paper, a mixed process neural network (MPNN) based on Fourier orthogonal base function has been proposed to support churn management, which can deal with both static value and time-varied continuous value simultaneously. To further improve its performance, an optimized network, c-MPNN, has been presented, which adopts Fourier expansion based preprocessing and hidden layer combination techniques to optimize MPNN's structure. Most important of all, our method has been used in real applications in China Mobile. Experiments based on the real datasets also show that our proposed churn prediction method has good maneuverability and performance
