Abstract

Once banks are no longer able to collect money from defaulted accounts, they turn to third-party debt collectors to recover the funds. These debt collectors use aggressive tactics, such as contacting the debtor’s family and friends, to try to locate the money. Because of this, many people have become afraid of ever becoming delinquent on their loan payments again. This has led to a decrease in the number of people who are able to become debt-free. This chapter presents machine learning models for optimization debt collection for South African banks. The main objective of this study is to compare the accuracy and cost optimization of logistic regression (LR), random forest (RF), multilayer perceptron (MLP) and decision tree (DT) models using bank delinquency data. Findings reveal that the LR and RF classifiers achieved the highest debt recovery rates. Since the LR model only considers SMS as a communication mode compared to RF, which has diverse communication modes, the RF model is selected as the optimal model to prescribe communication strategies. Communication strategies are based on classifiers that have the highest Hamming score, high subset accuracy, lowest action cost and diversity of communication modes.
