Abstract

The invention discloses a sample processing method and a device, equipment and a computer storage medium, and the sample processing method comprises the steps: obtaining labeling results of T preset attributes associated with each first sample in N first samples, and a proportion condition corresponding to each preset attribute, wherein the labeling result of the preset attribute is used for indicating whether the first sample comprises the preset attribute, and the first sample is multimedia data; according to the labeling result and the proportion condition, determining the number of times of copying each first sample; copying each first sample according to the number of copies of each first sample, obtaining P second samples, wherein the number proportion of the second samples with the target attribute in the P second samples meets the proportion condition corresponding to the target attribute, the target attribute is any preset attribute, and P is an integer larger than 1. The embodiment of the invention can effectively solve the problem of unbalanced sample categories and improve the quality of the sample set.

Description

technical field [0001] The present application belongs to the technical field of machine learning, and in particular relates to a sample processing method, device, equipment and computer storage medium. Background technique [0002] As we all know, in the field of machine learning technology, labeled samples are usually used to train machine learning models. However, in some application scenarios, the samples may have class-imbalance, that is, the number of samples of different classes is quite different. [0003] When dealing with the problem of class imbalance, the existing techniques usually copy the samples of the category with a small proportion. However, this processing method may lead to a reduction in the proportion of samples of other categories, and it is difficult to effectively solve the problem of category imbalance. Contents of the invention [0004] Embodiments of the present application provide a sample processing method, device, device, and computer stora...
