Data mining method, device and equipment and readable storage medium

The invention relates to the technical field of artificial intelligence, in particular to a data mining method, device and equipment and a readable storage medium, and the method comprises the steps: collecting a plurality of original data of a power grid from a database; inputting the plurality of original data into a pre-trained model for screening and classifying the original data; inputting the screened original data of the same type into a classifier to divide a classification result to obtain a divided normal data sample and an abnormal data sample; and marking and filtering the abnormal data sample, increasing the weight of a normal data sample, and outputting the normal data sample as available data. According to the method and the device, the unavailable abnormal data samples are marked and filtered, and the phenomenon that the abnormal data samples are repeatedly collected during next data collection can be prevented while marking is carried out, so that the probability of occurrence of the same abn
