Problems solved by technology

[0003] Due to the large amount of data, the traditional recognition method removes the NaN (Not a Number, ambiguous numerical result) value in the data, resulting in less training data. The fitting situation leads to low recognition accuracy and low recognition efficiency

Abstract

The embodiment of the present application provides a user identification method, device, electronic equipment, storage medium, and computer program product containing instructions, which relate to the technical field of computer communication networks. By filling the abnormal data in the sample user data with the median, Splitting the data of the string type in the sample user data by One-Hot encoding and based on the cardinality of the data of the enumeration type in the sample user data The method of obtaining enumerated data of multiple feature dimensions preprocesses the sample user data to obtain the preprocessed sample user data, which increases the amount of training data for the deep learning network model and reduces the risk of overfitting In case of occurrence, the user data to be processed is input into the deep learning network model to identify illegal users, thereby improving the accuracy and recognition efficiency of illegal user identification.

Description

technical field [0001] The present application relates to the technical field of computer communication network, in particular to a user identification method, device, electronic equipment and storage medium. Background technique [0002] With the continuous development of Internet technology, multi-level network security threats and security risks are also increasing. Among them, black production refers to the use of the Internet as the medium and network technology as the main means to provide for the security of computer information systems and the order of cyberspace management. Even illegal acts that pose potential threats to national security and social and political stability, the users used on the computer network are black users. For example, there are a large number of unscrupulous users who upload videos on the video platform. These unscrupulous users may have the following characteristics: uploading videos in batches, uploading videos through blacklisted channels...
