A Recommendation System For Insurance Built With A Multivariate Hawkes Process Based On Customers' Life Events

Abstract

We construct a recommendation system for insurance with a Multivariate Hawkes Process, in order to take into account the influence of life events (e.g. marriage, birth, change of job) on the insurance covering selection from customers. This Multivariate Hawkes Process includes several specific features aiming to compute relevant recommendations to customers from a Luxembourgish insurance company. Some of these features are intent to propose a personalized background intensity for each customer thanks to a Machine Learning model, to use triggering functions suited for insurance data or to overcome flaws in real-world data by adding a specific penalization term in the objective function. Our recommendation system has been backtested over a full year. Observations from model parameters and results from this back-test show that taking into account life events by a Multivariate Hawkes Process allows us to improve significantly the accuracy of recommendations.
