A comparative study on base classifiers in ensemble methods for credit scoring

作者:

Highlights:

• Small improvements in the systems about credit scoring can suppose great profits.

• Ensembles of classifiers achieve the better results for credit risk assessment.

• To look for the best base classifier used in ensembles on credit datasets is an important task.

• Via experiments, it is shown that the credal decision tree classifier is the best one to be used in ensembles.

• The study uses several of the most successful ensemble schemes and single classifiers.
