Abstract

The invention discloses a data enhancement method, system and device and a computer readable storage medium. The method comprises the steps: determining whether concept drift occurs in a current data enhancement method or not; if the current data enhancement method generates concept drift, generating a target data enhancement method; judging whether the target data enhancement method meets a data enhancement performance index or not; and if the target data enhancement method meets the data enhancement performance index, performing data enhancement on the online data based on the target data enhancement method to obtain target data. According to the data enhancement method, the target data enhancement method can be generated after the current data enhancement method generates concept drift, and the target data enhancement method is applied to perform data enhancement on the online data after the target data enhancement method meets the data enhancement performance index, so that the data enhancement method for updating the online data in real time is realized; therefore, the concept drift phenomenon can be avoided, and the accuracy of data enhancement is ensured.

Description

technical field [0001] The present application relates to the technical field of data processing, and more specifically, to a data enhancement method, system, device, and computer-readable storage medium. Background technique [0002] In deep learning, data can affect the upper limit of the deep learning model. The larger the data scale and the higher the data quality, the better the performance of the deep learning model obtained from data training. However, in practical applications, there are small and unbalanced data. , In the case of over-fitting of the deep learning module, in order to avoid these situations, the data scale can be expanded through data enhancement methods. [0003] The data enhancement method refers to expanding the training data similar to the real data through the transformation method while keeping the labels consistent, that is, for a sample, new data is generated through the transformation function, and the old and new data have the same data labe...
