Abstract:
Conventional financial decision support systems are based on distinct individual
attributes like gender, marital status, age and occupation, while being unaware of the habits or
spatio-temporal mobility of the individuals. The rapid growth of mobile payment and geo-
aware systems, and the emergence big data, present the opportunity to investigate human
consumption patterns across space and time. With this opportunity, we analyze a 1 year
transaction data of one of the largest banks in Türkiye to seek the relation between mobility
behaviors and product usage patterns for Individual Consumer Loan and Retirement Savings
products. After turning the raw data into a useful format with various data preprocessing
techniques, we filter the customers who provide more information in terms of mobility.
Afterwards, in order to evaluate the product recommendation model in different
circumstances, we divide the data into different scenarios with respect to the last 3 months’
product usage pattern, data time period, demographic, financial and mobility features. After
obtaining the best feature selection methods and classification algorithms for each dataset
independently, we analyze the results and discover interesting product usage patterns and
customer characteristics about selected products.
