    Case1: Personal loan default forecast

    Target

    • Build loan default model to evaluate users default probability
    • Give reasonable credit line to users
    • Allow line employees and managers to select data for modeling based on experience, and press forward the use of models among them
    • Increase rate of default capture

    Pain points

    • Find a reasonable data dimension
    • The impact of high cardinality and nonlinear problems on modeling
    • Select the right model or model combination
    • Avoid overfitting due to less positive samples

    First 20% 4.8 96%

    The current purchase rate of the financial product is 1.72%

    1. The purchase rate of the first 5% data using the model is 14.4 times higher than that without the model. That is, for every 100 selected customers, 24.77 transactions can be completed. It is far higher than the average of 1.72 transactions per 100 customers.
    2. 72.0% of the target customers can be captured from the first 5% of the data grabbed by the model. 96.0% of the target customers can be captured from the first 20% of the data grabbed by the model.
