| Abstract: | A new credit assessment model is applied based on random Forest algorithm to calculate the importance of individual character.This model provides the basis for the selection in its evaluation index system by random Forest.The experimental results on German dataset show that the credit assessment model based on random Forest and naive Bayes has higher prediction accuracy. |
