Abstract

The embodiment of the invention provides a feature processing method and device, and the method comprises the steps: carrying out the digital coding of an operation behavior under the condition that the terminal equipment detects the operation behavior of a user for the terminal equipment, and obtaining a corresponding behavior feature; storing the behavior features in a first feature pool, and configuring the plurality of service prediction models to perform corresponding service prediction by using the coded behavior feature sequence read from the first feature pool.

Description

technical field [0001] This specification relates to the technical field of data processing, and in particular to a feature processing method and device. Background technique [0002] As the infrastructure of terminal intelligence becomes more and more advanced, various network models for business forecasting are gradually deployed on terminal devices. For example, risk control models in electronic payment security risk prevention and control scenarios are gradually deployed on terminal devices. It is used for risk prediction for electronic payment scenarios on terminal devices. [0003] In some scenarios, the timeliness requirement for network model calculation for business forecasting is high, and it is a serial calculation mechanism on terminal devices, while some network models for business forecasting, such as risk control models, have The problem of repeated processing of the same data, which makes it more time-consuming in the calculation process. [0004] Therefore...
