Fuzzy neural network data mining method based on particle swarm optimization

Abstract

The present invention discloses a fuzzy neural network data mining method based on particle swarm optimization. The method comprises the following steps: cleaning and selecting power data; carrying out enhancement processing on the selected data, and converting the processed data into a form suitable for a neural network model; randomly dividing the obtained data into three data sets: a training data set, a test data set and a confirmation data set, wherein the first two data sets are used to train the neural network, and test the accuracy of the network to construct the neural network model,and the confirmation data set tests the network independently; determining the fuzzy neural network learning algorithm and training the fuzzy neural network; extracting rules from the trained fuzzy neural network; and evaluating the extracted rules. The method is more efficient in mining data in the cockpit of the power system, ensures to obtain optimal power system data mining results, provides decision support for dispatchers and managers, and ensures safe, stable, high-quality and cost-effective running of the power system.
