An Evaluation of Support Vector Machines in Consumer Credit Analysis
نویسنده
چکیده
This thesis examines a support vector machine approach for determining consumer credit. The support vector machine using a radial basis function (RBF) kernel is compared to a previous implementation of a decision tree machine learning model. The dataset used for evaluation was provided by a large bank and includes relevant consumer-level data, including transactions and credit-bureau data. The results suggest that a support vector machine offers similar performance to decision trees, but the parameters specifying the softmargin constraint and the inverse-width used in the RBF kernel could significantly affect its performance.

متن کاملSupport vector machines for credit scoring and discovery of significant features
The assessment of risk of default on credit is important for financial institutions. Logistic regression and discriminant analysis are techniques traditionally used in credit scoring for determining likelihood to default based on consumer application and credit reference agency data. We test support vector machines against these traditional methods on a large credit card database. We find that ...
