Abstract: This paper proposed a line loss calculation based on the self-organizing competitive network of the RPROP neural network to find efficient loss reduction measures and provide the basis for scientifically formulating line loss targets.The RPROP neural network ensured that the network could converge under a limited number of training times. Moreover, it utilized a self-organizing competitive neural network to effectively classify informative data, which improved the output accuracy of the RPROP neural network.By doing simulation experiments on the MATLAB platform and comparing with linear regression algorithm, standard BP neural network algorithm, unclassified RPROP algorithm,it verified the effectiveness of the proposed method.
Key words: linear regression algorithm; BP neural network; RPROP neural network; self-organizing competitive neural network; line loss
