RISK IDENTIFICATION MODEL BUILDING METHOD, APPARATUS AND DEVICE AND RISK IDENTIFICATION METHOD, APPARATUS AND DEVICE

摘要

A risk identification model building method, apparatus, and device and a risk identification method, apparatus, and device are disclosed. The risk identification method includes: obtaining user state records of a target user within given duration, where the user state records include user operation behavior and/or system events; sorting the user state records based on occurrence time, and generating a user state sequence based on a sorting resu converting the generated user state sequence into a sequence feature; and outputting a risk identification result by using the sequence feature as input of a pre-built risk identification model.
