Deep learning techniques can assist marketing decision makers to provide more reliable and practical marketing strategic plans. In this paper, we propose a customer behaviour prediction model using recurrent neural networks (RNNs) based on the client loyalty number (CLN), recency, frequency, and monetary (RFM) variables. The experiment results show that RNNs can predict RFM values of customers efficiently. This model can be later used in recommender systems for exclusive promotional offers and loyalty programs management.
