Abstract
Extreme Learning Machine (ELM) is currently a very popular type of machine learning algorithm, which is used to train a single layer feedforward neural network (SLFN). Aiming at the drawback that the ELM method cannot independently optimize the optimal network, this study uses the particle swarm algorithm to select the optimal hidden layer deviation and input weight matrix. The proposed PSO-ELM method is compared with the traditional ELM method in simulation. The accuracy of the prediction results on different gasoline octane content data has been improved. Finally, the conclusion and some potential research are summarized.
