Electricity Theft Detection Based on Bagging Heterogeneous Ensemble Learning
Aiming at the deficiency of the single classification method in traditional electricity theft detection
this paper proposes an electricity theft detection method based on Bagging heterogeneous ensemble learning. Considering the performance of different individual learners on the data sets and the diversity between various learners
an electricity theft detection model based on Bagging heterogeneous ensemble learning with combination of various individual learners is developed. The individual learners of the model include the k-nearest neighbors
the error back propagation network
the gradient boosting decision tree and random forest. The outputs of the individual learners are combined by an improved weighted voting strategy. The Irish smart meter data set is used to verify the feasibility of the algorithm. The results show that
compared with the traditional single model
the electricity theft detection based on Bagging ensemble learning has better performance in accuracy
true positive rate and false positive rate. The sensitivity analysis shows the validity of the electricity theft detection method based on Bagging heterogeneous ensemble learning.
