Cost-sensitive boosted tree for loan evaluation in peer-to-peer lending

作者:

Highlights:

• A novel cost-sensitive boosted tree model is proposed for loan evaluation in P2P lending.

• An improved portfolio allocation model is designed using integer linear programming with boundary constraints.

• Explanatory variables differ in predicting the probability of default and profitability for P2P loans.

• Traditional loan evaluation models may not guide profitable decisions.

• The proposed models outperforms several popular benchmark techniques in terms of profitability.
