I. Introduction
Traditionally insurance companies determined automobile policy premiums using rate tables computed by Actuaries. Today however, the vast amount of data collected in electronic form can now be used to determine more suitable premiums for a given policy since such data can be used to better predict risk [1]. This form of personalized policies benefit the customer (who pays an amount more in line with their risk) as well as the insurance company (which can now better ensure that it can safely cover claims costs across all of its customers). The typical approach is straightforward. For a given new customer, one can use historical data of past and present customers with similar characteristics (attributes) to better estimate the risk level of the new customer and then use this to determine a premium for their policy. This is similar to the recommender systems used by companies such as Netflix. In that case movies are recommended to an individual based on movies that were enjoyed by customers with similar characteristics. In the case of insurance, one must “recom-mend” a policy that is both desirable to the customer (through personalization) and profitable to the insurance provider.
