Document Type and Number:
WIPO Patent Application WO/2022/095352
Kind Code:
A1
Abstract:
An abnormal user identification method and apparatus based on intelligent decision, a computer device, and a storage medium, relating to the field of artificial intelligence. The method comprises: acquiring an original dataset; performing data recombination on the original dataset to obtain a tagged sample and an untagged sample; inputting the tagged sample into a first user identification model to perform first training on the first user identification model to obtain a second user identification model; performing data augmentation on the untagged sample to obtain an augmented untagged sample set corresponding to the untagged sample; performing second training on the second user identification model by means of the tagged sample and the augmented untagged sample set corresponding to the untagged sample to obtain an abnormal user identification model; and inputting a user sample to be identified into the abnormal user identification model to obtain the user identification result. In addition, the method also relates to a blockchain technology, and the original dataset can be stored in a blockchain. The method improves the accuracy of abnormal user identification.
