An optimization method and device for strategy allocation

Abstract

Disclosed are an optimization method and device for strategy configuration. A strategy configuration optimization method, the method includes: determining the strategy configuration to be optimized in the initial strategy; obtaining the prediction result output by using the current strategy configuration in the strategy to the preset test data, and performing statistics on the prediction result to obtain at least one Index value, the index value is used to judge whether the current business index meets the preset requirements; if the current business index does not meet the preset requirements, the policy configuration is optimized, and the optimization process includes: Adjust the combination of risk features, adjust the digital symbols used to represent the relationship between risk features and feature values, or adjust the feature values ​​corresponding to the risk features included in the policy configuration; after optimization, if the current business indicators If the preset requirements are met, it is determined that the policy configuration in the current policy is an available policy configuration.

Description

technical field [0001] The embodiments of this specification relate to the field of computer technology, and in particular, to a method and device for optimizing policy configuration. Background technique [0002] Third-party payment refers to an online payment model in which an independent institution with certain strength and reputation guarantee facilitates the transaction between the two parties through the connection with the Nets Union. In third-party payment, the user's operation behavior is recorded in the form of events, such as user login events, user registration events, user transaction events, etc., and the recorded events are sent to the risk control platform. The risk control platform utilizes The risk identification strategy and risk control strategy inside the platform identify and control the risks of events that represent user operation behaviors (also known as risk control events). If the events are risky, it means that the user's operation behavior has c...

Problems solved by technology

[0004] At present, the way to optimize the strategy configuration in the risk identification strategy or the strategy configuration in the risk control strategy is: the operation and maintenance personnel analyze the existing cases based on their own experience (events that represent user operation behaviors are risky, but the risk control platform does not identify them. Events that show that there is a risk in the event that characterizes the user’s operation behavior, and the event that causes the user’s account funds to be damaged are called cases), and the strategy configuration in the risk identification strategy or the strategy configuration in the risk control strategy is optimized, that is, through manual methods. optimization

The existing method needs to rely on the experience of the operation and maintenance personnel, and the operation and maintenance personnel need to analyze the existing cases before they can optimize the policy configuration in the risk identification strategy or the strategy configuration in the risk control strategy, and the cycle is relatively short. long
