The invention discloses an electricity charge abnormal data analysis method and device, terminal equipment and a medium, and the method comprises the steps: preprocessing historical electricity charge data and to-be-detected electricity charge data to acquire first data and second data; dividing the first data into a training sample and a test sample according to a preset proportion; training the deep forest model by using the training sample, inputting the test sample into the trained deep forest model, and calculating a numerical value of an evaluation index of the deep forest model according to an output result; judging whether the numerical value reaches a preset threshold value or not, and if yes, taking the current deep forest model as a target model; if not, returning to execute the training operation on the deep forest model by using the training sample, and taking the corresponding deep forest model as a target model until the numerical value reaches a preset threshold value; and inputting the second data into the target model to generate an electricity charge abnormal data classification result. The electricity charge data is analyzed based on the deep forest model, and the analysis efficiency and the result accuracy are improved.
Description
technical field [0001] The present invention relates to the technical field of machine learning and data analysis, and in particular to a method, device, terminal equipment and medium for analyzing abnormal electricity bill data. Background technique [0002] At present, the analysis method for abnormal electricity bill data mainly adopts manual analysis method, that is, users with abnormal electricity bills are screened out through manually formulated logic rules. However, because such methods are dominated by subjective factors such as human experience, they have more uncertainties and require a lot of manpower and material resources. Therefore, the existing thermal analysis methods are not ideal in terms of efficiency, accuracy and recall. Contents of the invention [0003] The purpose of the present invention is to provide a method, device, terminal equipment and medium for analyzing abnormal electricity bill data, so as to solve the problems of low efficiency, accura...
