Abstract

This specification discloses a method, device and equipment for identifying risk objects. The method includes: acquiring a plurality of objects to be identified, where the objects to be identified include at least an event and / or media information corresponding to the event; creating a composition according to the event and / or media information corresponding to the event, and obtaining at least A composition; each event and / or medium information on the composition is determined according to the label information and the weight on the composition that mark the event and / or medium information before a certain time point on the composition in the process of training the classifier features; according to the features of the events and / or media information on the composition, use the trained classifier to classify the events and / or media information after a certain time point, and obtain the risk objects among the objects to be identified.

Description

technical field [0001] This description relates to the field of computer technology, in particular to a method, device and equipment for identifying risk objects. Background technique [0002] The vigorous development of Internet technology has brought people a convenient life. At the same time, it also brings many disadvantages to people's life. For example, there are currently risky behaviors such as card theft, account theft, fraud, and spam account registration on the Internet. [0003] Traditional risk control systems usually convert the problem of identifying the above-mentioned risky behaviors into a binary classification problem (solve the binary classification problem through machine learning) or directly use an expert system. However, the expert system has subjective assumptions about some thresholds, which will distort the objective facts, resulting in low accuracy of identified risk objects. Machine learning can learn the threshold and weight of each feature o...
