Abstract:
With the development of power user information collection system, richer user electricity consumption information is used for the identification of user electricity consumption information anomalies. In this paper, a false data injection based on the 易球娱乐官网地址 attack is performed to construct a dataset of user electricity consumption information anomalies, and an improved stacking integrated classification algorithm based on recall is proposed. K-nearest neighbors algorithm (KNN), random forest model (RF), support vector machine (SVM) and gradient decision tree (GBDT) are used as the scheme of base classification model of the stacking structure. Logistic regression (LR) is used as a meta-classification model of the stacking structure. The output of the basic classification model is weighted based on the recall rate, which is used as the input data set of the meta-classification model. The proposed improved stacking classification algorithm based on recall is shown to be more efficient than the traditional stacking classification algorithm.
