[0065] Specific embodiments of the present invention are given below, and the present invention is described in detail in conjunction with the accompanying drawings.
[0066] Figure 1A It is a flow chart of the prediction method based on the forest discrimination model of the present invention. Such as Figure 1A As shown, the method includes:
[0067] Step 1, using modeling data to perform modeling based on the random forest algorithm, binning the modeling data, and solving the discriminative model to obtain the modeling result;
[0068] Step 2: Scoring the data to be predicted according to the established model and the modeling results to obtain a prediction result.
[0069] Further, the step 1 includes:
[0070] Step 11, binning the modeling data based on the random forest algorithm to obtain a binning result;
[0071] Step 12, converting the variables of the modeling data into dummy variables according to the binning results, and using the dummy variables to solve th...
