Problems solved by technology

For example, when the user's account is deducted by the partner through illegal methods such as collection and hidden deduction, it will cause the user to suffer property losses and cause user complaints; The payment business is running normally; in addition, some users who are more sensitive to the consumption situation will increase the possibility of complaints when the deduction of the payment business exceeds the sensitive value

Abstract

The invention discloses a risk management model training method. The method comprises: a first historical data group of known results is obtained, wherein the first historical data group includes account information of an abnormal user; according to the type of the account information, a data mining model with a highest fitting degree is selected as a first stage model; dimensionality of account information in first historical data is adjusted by using the first stage model to generate a second historical data group; and after the first stage model is trained by using a first data set in the second historical data group, the first stage model is verified by using a second data set in the second historical data group and a risk management model is selected based on a verification result, wherein the risk management model is used for identifying an abnormal user in telephone bill payment. In addition, the invention also discloses a risk management model training apparatus. With the method and apparatus, a complaint rate can be reduced.

Description

technical field [0001] The invention relates to data processing technology, in particular to a method and device for training a risk control model. Background technique [0002] During the operation of network and telecommunications payment services, payment exceptions may occur. For example, when the user's account is deducted by the partner through illegal methods such as collection and hidden deduction, it will cause the user to suffer property losses and cause user complaints; The payment business is running normally; in addition, some users who are more sensitive to the consumption situation will increase the possibility of complaints when the deduction of the payment business exceeds the sensitive value. [0003] Only by accurately identifying the abnormal users that appear during the operation of the network and telecommunications payment services, can timely take corresponding measures for the abnormal users. Contents of the invention [0004] In order to solve t...
