Abstract

Model training and risk identification methods, devices and equipment are disclosed. By extracting the user's event sequence and the screen track information on a single event, and extracting the single user event feature for the event from the screen track information and the sequence number of the event, and then generating the event sequence feature corresponding to the event sequence , so as to reflect the relevant characteristics of user behavior through the event sequence feature, realize the training of the model according to the event sequence feature, obtain the available target model, and use the trained target model to identify the risk of the user's screen trajectory.

Description

technical field [0001] The embodiments of this specification relate to the field of information technology, and in particular, to methods, devices, and equipment for model training and risk identification. Background technique [0002] In marketing activities, illegal users often control machines to register junk accounts in batches, and then use junk accounts to participate in marketing activities initiated by business parties to defraud marketing funds; even use junk accounts to conduct fraud, cash out and other illegal activities. For example, black products use pre-edited codes to control the registration process and register junk accounts in batches. It is difficult to realize the identification of junk trumpets in batches by conventional or manual methods. [0003] Based on this, there is a need for an efficient identification scheme for batch-registered junk accounts. Contents of the invention [0004] The purpose of the embodiments of the present application is t...
