The embodiment of the invention provides a data processing method and device, electronic equipment and a computer readable storage medium, and belongs to the technical field of computers. The method comprises the steps of obtaining feature information of an object; obtaining the relevancy of the features according to the feature information of the object; clustering the objects according to the relevancy of the features to obtain a clustering result, wherein the objects with the small proportion in the clustering result serve as minority class samples, the objects with the large proportion inthe clustering result serve as majority class samples, the ratio of the number of the minority class samples to the number of the majority class samples is 1: N, and N is the data imbalance multiplying power and is a positive integer larger than 1; diffusing the minority class samples based on the minority class samples and the majority class samples to obtain synthesized minority class samples; and training the classification model according to the minority class samples, the majority class samples and the synthesized minority class samples. Through the scheme provided by the embodiment of the invention, the sample can be automatically labeled, and a lot of manpower and material resources are saved.
Description
technical field [0001] The present disclosure relates to the field of computer technology, and in particular, to a data processing method and device, electronic equipment, and a computer-readable storage medium. Background technique [0002] In related technologies, the labels of the samples in the training data set used to train the classification model are manually labeled, which consumes a lot of manpower and material resources, is inefficient, high in cost, and errors are prone to occur in the manual labeling process. [0003] Therefore, a new data processing method and device, electronic equipment, and computer-readable storage medium are required. [0004] It should be noted that the information disclosed in the above background technology section is only for enhancing the understanding of the background of the present disclosure. Contents of the invention [0005] Embodiments of the present disclosure provide a data processing method and device, electronic equipmen...
