For example, this method first trains the data obtained by the existing risk control system through the logistic regression algorithm to obtain the model weight, and then converts the model weight into the sub-rule score in the form of weight accumulation according to the risk level of each sub-rule. The low-level scores of the same type of rules are accumulated to the high-level to ensure that the hi...
