    • Customer life event prediction using deep learning
      Arno De Caigny (IESEG School of Management)
      Co-authors: Arno De Caigny
      Life events, such as the birth of a child or moving, can have a major impact on the relation between customers and the company because customers might re-evaluate their consumption behavior and customer needs. Therefore it is crucial for companies to manage the customer relation during these important moments. Companies, however, often only have systems in place to detect life events and are thus limited to reactive marketing approaches towards customers who encounter a certain life event. The prediction of such life events would enable companies to pro-actively engage with their customers by means of life-event marketing. In this study, structured and fine-grained payment data from a European financial services provider are used to predict four different life events (moving, birth of a child, new relationship, end of a relationship). The structured data consists of more than 200 variables that describe customer demographics, customer behavior and the customer contact with the company. The fine-grained payment data contains more than 60 million debit transactions from about 130,000 customers. Today, deep learning algorithms show promising results in many different applications that are characterized by high sparsity and high dimensionality. Therefore, we will test different deep learning algorithms and benchmark them against current best practices to integrate the information of fine-grained payment data in a predictive customer scoring model.
