Abstract

The invention discloses a mathematical modeling method and system, equipment and a computer readable medium. The mathematical modeling method comprises the following steps: a strict variable screening step; a step of mining client setting information as variables; a step of screening the variables through set features of the variables; and a model training step. The external resource information characteristics are independently modeled, model results are fused in cooperation with models established by other characteristics, and when the external resource information has a problem, only the resource information model is adjusted without affecting the whole model; and products with similar distribution and scenes are combined together for modeling. According to the mathematical modeling method, the system, the equipment and the computer readable medium provided by the invention, the stability of the mathematical model can be improved, and meanwhile, the recognition efficiency and accuracy of the customer quality can be improved. According to the method, the instability of variables and the over-fitting of the model can be reduced, and the influence of data instability on model training and the final effect is reduced as much as possible.

Description

technical field [0001] The invention belongs to the technical field of mathematical model building, and relates to a modeling method, in particular to a mathematical modeling method, system, equipment and computer-readable medium. Background technique [0002] Risk control is the key to finance. With the development of the times, a general trend in the field of risk control is that the degree of informatization, modeling, and intelligence is getting higher and higher. [0003] In the process of risk control modeling, the stability of the model is affected because the external credit information is unstable due to the influence of the external environment. In addition, since there are many types of risk control products, it is necessary to establish a corresponding mathematical model for each risk control product, which requires a large workload, and the identification efficiency of the model for customers is low. [0004] In view of this, there is an urgent need to design a...
