机译:训练风险控制模型和风险控制的方法,装置和设备

摘要

Implementations of the present specification disclose a risk control model training and risk control method, apparatus, and device. In a risk control model training stage, historical data in a specified time period can be obtained, and the specified time period can be divided into sub time periods; then, respective features of the historical data in each sub time period can be determined, and respective features of the historical data in the sub time periods can be sorted based on a specified sorting rule of the sub time periods to obtain a feature sequence; and finally, the obtained feature sequence can be used as a sample to train a risk control model.
