Title:
DATA CLASSIFICATION METHOD, APPARATUS, DEVICE AND COMPUTER READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2019/169704
Kind Code:
A1
Abstract:
Provided in an embodiment of the present application are a data classification method, apparatus, device, and computer readable storage medium. In a circumstance in which two classes of samples are unbalanced, for a large number of samples, several same class sample sets are generated by means of downsampling; and for a few classes of samples, new samples are generated by means of upsampling; the new samples are used for mixing with the few classes of samples to form a relatively large number of samples, such that the number of samples of a sample set in which the original numbers are few is balanced with the number of samples of a sample set in which the original numbers are many; and the few classes of samples and many classes of samples predict data by means of multiple modeling, and finally a prediction result having a quantitative advantage is taken as a classification result. The accuracy of the data prediction is improved by means of a means of upsampling, downsampling and multiple-modeling multiple-predictions.
