英文摘要：

This paper focuses on the customer churn prediction in the field of customer relationship management. Based on the characteristics of customer churn data and the comparison of the current prediction algorithms, we introduce random forests algorithm, a new data mining method, into the customer churn prediction and build a prediction model. Applied to a credit debt customer database of a commercial bank, the model is proved to be effective in classifying the churn customers from the loan data.
