Abstract

The invention discloses a user behavior prediction method and system based on time sequence characteristics, and computer equipment. The method comprises the following steps: acquiring time sequence feature data of a user to be predicted, wherein the time sequence feature data is user feature data corresponding to a plurality of time points in resource return time; according to the time sequence feature data, generating time sequence feature evaluation data of the to-be-predicted user, the time sequence feature evaluation data being used for representing a change condition of the user feature data according to a time sequence; and based on a pre-trained machine learning model, according to the time sequence feature evaluation data, obtaining a prediction value of the user behavior occurrence probability of the to-be-predicted user. The user feature data can be more effectively utilized; and the feature evaluation data containing the feature change information caused by the time factor is used as the model input feature data, so that more accurate input feature data can be provided for model calculation, and the user behavior occurrence probability can be more accurately calculated.

Description

technical field

[0001] The present invention relates to the field of computer information processing, in particular to a user behavior prediction method, system and computer equipment. Background technique

[0002] Risk control (referred to as risk control) means that risk managers take various measures and methods to eliminate or reduce the various possibilities of risk events, or risk controllers reduce the losses caused by risk events. Risk control is generally used in the financial industry, such as risk control for company transactions, business transactions or personal transactions.

[0003] In related technologies, a risk control method based on user login behavior analysis is disclosed. The method establishes and integrates user button risk identification, user login location risk identification, password retry risk identification, and device source risk identification through user login behavior. A model to obtain risk warning value. The risk prediction accuracy o...
