A Cost-Sensitive Logistic Regression Credit Scoring Model Based on Multi-Objective Optimization Approach

Abstract: Credit scoring is an important process for peer-to-peer (P2P) lending companies as it determines whether loan applicants are likely to default. The aim of most credit scoring models is to minimize the classification error rate, which implies that all classification errors bear the same cost; however, in reality, there is a significant cost-sensitive problem in credit scoring methods. Therefore, in this paper, a new cost-sensitive logistic regression credit scoring model based on a multi-objective optimization … Show more

“…Studies related to credit risk modelling have significantly grown during the past 50 years, with most notable breakthroughs by Altman (1968) and Merton (1974). For the last 20 years classical modelling techniques have been challenged, as researchers have been discussing modelling credit risk by applying different machine learning techniques (Qu et al, 2019;Atiya, 2001;Pickert, 2017;Shen et al, 2020;Uthayakumar et al, 2020). One of the first machine learning tool application in financial distress prediction was by Atiya (2001) who used Artificial Neural Networks in classic credit risk prediction model developed by Merton (1974).…”

“…Efficiency in this case is time and material costs reduction for working with borrowers who have overdue credit debt. The collection activity optimization is possible due to the modern methods of intellectual analysis of accumulated data use Dela Cruz Galapon, 2020) and the effective collection scoring models construction (Shen et al, 2020;Terko et al, 2019). Such models are able to minimize the time spent working with clients to collect overdue debts, and the total time spent on activities, and maximize profits from collection activities.…”

“…(4) Misclassification cost. Since cost-sensitivity usually occurs in credit scoring, accuracy can seldom provide an overall evaluation on the label prediction (Shen et al, 2020). As a result, we follow Lohmann and Ohliger (2019) to evaluate the capability of label prediction by misclassification cost defined as follows:…”

“…In a highly imbalanced dataset, credit scoring model tends to predict all the applications as the majority class (usually non-default) and thus lacks the capability to discriminate risky ones (Sahin et al, 2013). Cost-sensitive learning is a solution to imbalanced dataset, which can be roughly divided into the direct method and indirect ones (Shen et al, 2020;Xia et al, 2017b). The direct cost-sensitive learning methods design models that are cost-sensitive in themselves, whereas the indirect methods transform the cost-insensitive models into cost-sensitive one by sampling or thresholding.…”
